Nothing from Asian or Latin America.” “No” “What about spaghetti or roast a chicken with veggies and mash potatoes”? “I guess” “Which one?” “I don’t know”.

[@timothycallahan6234]

Once upon a time, I tried to teach myself how to hotwire my 67 Newport in my HS parking lot, and I jumped line power to the wrong wire. I smoked the points, and had to clean them off with a Leatherman (life was different in the 90s in Rural MT). I drove it for a week before I actually bought new points for it. I still have those burned points in an Echlin box from '97, in my garage right now. Still have the car, too. I don't think an electronic ignition would've taken as kindly to my youthful indiscretion.

[@terryzeissler4199]

Hi Tony, this is a great conversation that should have been brought up a very long time ago. When I started in the trade as a tune up technician everthing was points. One thing that also wears out is the distributor cam lobes giving different point opening gaps from cylinder to cylinder. One of the reasons for electronic ignitions was to increase the spark firing times across the plug gap. The longer spark time was needed in order to keep the lean mixtures burning as they swirled around the combustion chamber. Spark times went from 1 1/4 milliseconds with .035 gaps to 2 1/2 milliseconds with .045 and greater gaps. Capacitive discharge ignitions have extremely short spark duration, only 1/8 of a millisecond and have a very difficult time keeping the flame going. This led to the multi spark idea, however I have never seen an explanation how three 1/8 ms sparks is supposed to be better than a single 2 1/2 ms one which, by the way is almost as long as the average 3 ms it takes for all of the mixture in the cylinder to completely burn. It's interesting that the OEM's that tried CDI (like Pontiac in the 60's) dropped it almost as fast as they could. Also the multi spark guys should put a switch on their boxes so it can be changed to a single spark so that a scope can synchronize and allow for diagnostics and cylinder balance tests. The GM HEI was almost to strong as it often would burn through the rotor and short out staight through to the shaft. The distributors also had a thin steel spacer washer between the gear and the bottom bushing that would stick if the car did not get regular oil maintenance and cut right through the shaft leaving you stranded. We pulled all distributors with every tune up, but the HEI also had the gear removed and the shaft pulled to check if was ok. The Ford Dura Spark was a good system as well. It's one biggest problem was the circuit board cracking in the module. The module was an aluminum box with sand and epoxy poured into it to seal and protect the electronics. Over time expansion and contraction with temperature changes would create cracks in the circuit board traces causing intermitant stalling. This was intermittant problem that was actually very easy to duplicate in the shop. Just unbolt the unit from the fender and with the engine running give the module a tap on the bottom with a small hammer and instant stall. Wish all intermittent problems were so easy. The Dura Spark was also unique in that 10 degrees of the advance curve was built into the module. Aftermarket modules did not have this so installing one led to loss of power and fuel economy. The Mopar system may not have had as big a punch to it but was very reliable. There was occasional failures of components but not often as the others. Probably about the same as a coil failure in point systems. The best aftermarket ignition system I ever came across was the Allison. This used an infrared light emitting diode and shutter in the distributor with an external module and coil. It had 3ms firing time during cranking and 2 1/2 to 2 3/4 ms firing time across the plug gap. Good for any number of cylinders and up to 12,000 rpm. It was developed by a professor Allison at a university in California. It later became the Crane Fireball Ignition and was awsome with an E-Core type coil. I saw a while back that someone else had it under a different name but I can't recall who it was at the moment. Keep up the good work Tony. Terry

Terry , it's amazing how rare that ms knowledge is ,,, !

[@terryzeissler4199]

@@rolandtamaccio3285 Roland, it is sad how much basic knowledge has been lost since cars jumped on the computer wagon. Diagnostics with hand held scanners mostly looks at the electronics but forgets that the internal combustion engine is still the same animal as it was 100 years ago. I learned to use a scope and gas analyzer in the 1970's and still own one today. Being able to see and measure what is happening in the combustion chamber, the ignition, fuel and exhaust in real time, as it is happening with analog equipment is lost to todays technicians. Relying on fault codes can often send you on a wild goose chase that ends up thowing parts at a problem that may not be needed. To me the data stream is more important to understanding a problem and leading to a solution. Computerized systems are very good at hiding internal engine problems as they try to keep it running no matter what. My mentor and friend Frank referred to the electroncs on a car as F.R.E.D. F-----g Ridiculus Electronic Device. Why does the service manual for my wifes 2015 Fiat 500L have to be 8,268 pages long? You only have to tell me how to remove the engine cover once, not over 300 times. Replace the battery and now I have to perform a battry reset, powerwindow module reset, throttle learn, etc., etc., etc. Change oil and I need a scanner to reset the oil reminder and turn out the dash light. Install an LED light bulb and the CAN buss freaks out. Leave a car sit for a few weaks and the battery goes dead from all the electronic drain on the system. We all want to work on our own cars but because of all the special tools required, software reprogramming that can only be done at the dealer, electrical breakout boxes required to test the electrical harness and connections we are forced to go back to the dealer and pay their inflated labour and parts rates. I think that after this rant I'm going to go out to the garage and do some more work on my 1967 Chrysler New Port Convertible. At least if a tail light doesn't work only need my 12 volt test light to fix it.

[@et76039]

I had an MSD system and liked it. The theory behind it was more complete ignition, somewhat like the dual spark plugs on some Ford 2.3 liter engines. My '71 Ranchero smoothed out with it, but it was also over carbureted.

[@JamesHolbrook-eh5sp]

Terry, that's all really good info. I don't know if it's the same system but I had a British Ford (I'm in the UK) from 1989 which had the Dura Spark. I used to call it Arthur after the 70s trade unionists who had Britain on a 7 day week in the 70s. I fixed it by putting a sheet of aluminum behind it as a heat sink and screwing that to the inner fender. After that no problem.

Its pretty decent and sorta easy to troubleshoot. I see it on a lot of 80s and 90s era generators with ford power. The one that had no spark on me , and was in the sticks, had a bad box. (This was pre COVID) So I look up a local napa and cross my fingers. I told the guy it's for a generator so forget what kind of car this thing came in...ok hold on lemme get the veteran..... Dude asked me what color the plastic was where the wires went in. Blue. Ok dude I got one come on down. Awesome,cause I was 2hrs from the shop and we pride ourselves on getting a unit operational. The power wasn't out , but that's what it's for and folks don't have generators for no reason. Good stuff man, I'm a huge fan of Ford industrial engines. 2.3,300 and the beautiful turbo 460 are all some of the best industrial engines of days gone by. GM kinda took over around the early 2000s.

[@peteloomis8456]

I used to work at a old bone yard back in the late 70s early 80s and we sold tons on those ignition modules . We had a 55 gallon drum full of them with each one marked from what they came off of & we had a shelf in the shop stacked full of them tagged with what each one came off of . They could be dead reliable but we had so many people coming in at times they must have had problems with them going bad on the road leaving people stranded . A old friend of mine his father stopped in to see if we had one for his Ford van and we did but I told him that these were known to burn out so if you can afford it but 2 of them and keep one as a spare in the van just in case the module takes a dump that way you can get it back up and running again . He never did come back again for a module after that but bought other parts from us for the van and other vehicles he had . I found out this friend of mine from way back then who lived about 2 miles from my parents house and I knew his whole family that he had committed suicide after his wife divorced him and left & took the kids and she brain washed the kids so bad that they wouldn't even come to see him after he tried to get them to come over for dinner to just talk & hang out & have a fire in the fire pit but they never gave him a chance & found out that someone else I new worked at the same place he did & that he didn't come into work & didn't call in & I was told that he never missed work so this person got a hold of his brother and he called the father and he had the police go out to the house with the father and they found him dead because he had hung himself. I wanted to go to the funeral but just couldn't make myself go because I didn't want to see the family in such pain after knowing them for so many years before I moved away . The only thing good about this is his ex wife will now be constantly reminded that what she told those kids and her brain washing them she's going to remember this for her whole life and unfortunately the kids as well who now will never get to see or talk to their father again and actually get to know him . I apologize for this not really being relavent to this video but after seeing the mention of the Ford style brain boxes it immediately brought me back to those days working in the bone yard and seeing his father at times coming into the shop to buy parts from us and what ultimately happened to my friend many years later and not seeing him or knowing where he was living at the time or even knowing that he had got married and had children.

I spent decades as a Mercruiser mechanic, mostly on the inline 4 and 6 cylinder engines. Back in the day, it was standard practice that a stern drive boat coming out of storage got new points, condenser, and plugs every season. When Mercruiser went to HEI distributors, that went away. We never touched them. But remember that these boats ran 143-165 degree thermostats and were surrounded by cool water. For ignition systems, it was like the Promised Land. I did install a couple of Mallory electronic distributors in two 4 cylinders, one to replace a worn-out points unit in an old 140, and one to replace a Delco electronic timing curve system in a 3-liter Lynx (spit and swear...) and never had to look at them again.

In 1990 I dropped in an HEI in my 400 LeMans. It ran so much better than with the points distributor. Two or three miles later tehe engine quit, probably the module popped. Anyway, the reason for it running better with the HEI was the shot bushing in the points distributor, making it misfire, mostly at idle. So the worn bushing is a real thing, it's what makes so many old engines make fluff and puff sounds at idle.

[@LongIslandMopars]

Yep. My 66 Coronet has a worn distributor bushing and the points were bouncing all over the place. The Pertronix cured that and it runs mint. Unfortunately, I'm on my 2nd Pertronix. Not going to invest in a third. If it craps out, I'm going to figure out my options.

[@mikekeil3974]

You nailed it Tony, I always use points in my old fords. Petronix is fussy and likes 12v , I have found the resistor wire in fords ignition drops the voltage to 8 v and petronix doesn't always run well with that voltage drop. Petronix works better than points on worn out distributors with bad bushings, seems to be more forgiving, however I will always be using points in my old cruisers and as you say the echlin points are the best I have found lately...if electronic ignition fail you are screwed on the side of the road, points, even if worn will always get you home....good video Tony

Something you should mention is that if you think you got an improvement you should measure it, 1/4 mile et increase or mpg increase. I bolted on an MSD box when I was in high school, I wanted more power didn’t have money so I went with this as one of my mods. I swore that it was faster, ran better but now that I’m older and able to analyze it I am pretty sure it was a placebo effect. Do not underestimate the placebo effect when playing with cars, you spend money to improve something, you want to justify it, you may think it is running better but in reality it made no difference.

I always learn something from your videos, I should ad that I am 65 and have been working on cars since i was 14. I did however spend my career in the electronics repair business. While it is easy to always blame the manufacturer, and sometimes I do, you also have to look closely at the consumer. If the average consumer is mainly focused on the lowest cost, retailers will search for lower priced product. Vicious cycle. In the case of aftermarket ignitions for classic cars, I have to point the finger of blame on greed or pure ignorance. These companies could, with a competent design engineer, provide a product that will work under the extreme conditions of the average engine bay. The added cost of the proper circuit design would most likely be a few dollars. I for one would rather pay up front

One person at a car show was telling me he hand wired his car front to back with all new, more modern connectors when and where possible, and brand new original style plugs where needed. Every other vehicle I have seen with a Pertronix ignition tended to be trailer queens and parade cars that did not get driven much, if at all, and I have seen them fail. There was a guy with a 440 Dodge Challenger (swapped from a 318) that broke down just as he pulled into a show I went to. Someone helped him swap to a points ignition he bought at the swap meet, and he was back up and running before the end of the show. Most people I have ever seen with daily driven, or at least often driven, classic cars tend to stick with points, or OEM electronic ignition.

Next pass, 2.07 60-foot time, 14.89 at 89.77 mph. That being said, hot ignitions are good for high power engines. More stock engines, not so much.

[@autumnjeserich2689]

I had a pertronix 2 fail on me that caused me to chase my tail for months. Was convinced it was a carb issue because it started intermittently before eventually the motor ran horrible all the time. Rebuilt the carb probably twice, did basic plug and wires, fuel pump, fuel pressure regulator, messed with my electric choke way too much. It wasn't until I did my vaccuum and mechanical advance, that it became clear it was an ignition problem and I changed the ignitor to another pertronix unit right away it started it up and sounded the best that motor ever had. I can't imagine the hei distributor did anything that would be noticeable to the power output of a 250-300hp chevy 350.Even on my LS engines with their individual coil packs I highly doubt makes any noticeable power output over a stock SBC points distributor. Getting the timing right is going to make a way bigger difference than the voltage of your spark

[@dkzero21]

On the Hei topic. I agree on aftermarket I wasted lots of money on hei units. I ended up getting an old hei unit and swapped it over and it has been flawless

[@roberttoews2775]

I swapped my 1968 Newport with the original 383 2bbl from points to Pertronix 16 years and just over 20,000 miles ago. Never had an issue. It was definitely worth it. The original parts are riding around with me in the glove compartment, but were never needed. Maybe I'm one of the lucky ones, but that's OK with me and my car. I could easily switch back to original, but I've had no reason too.

[@Z_732]

Lol.. perfect example of what I did with my 225. Dad dropped a points dist in it because he didn't understand the original chrysler electronic ignition wiring. When I got the truck, (ran very rough) the distributor wobbled bad enough the factory rotor would hit the cap and snap the tip. So I pulled the dist. Put an electronic system back in it. Still running it today. Runs fine, always hits.

[@maxx1able]

I wire the gm hei in place of ford duraspark and mopar boxes ...cheap and easy to wire to stock electronic oem distributors

[@b.snoodleman5864]

As a huge bonus HEI eliminates the need to set the points and dwell, also it is contactless so nothing wears out like the cam inside the point distributors do.

[@HARPO1ME]

Did many of those ignition conversions not from points but from mid 70s Chrysler lean burn systems that were garbage .Never had one fail and come back. Remember they had 2 different colored ignition modules you would bolt on the firewall backdating to standard ignition with a vacuum advance .They ran so much better and customers were really happy.

[@haircut2015]

VERY Good advice for factory igntion systems. I have a stock 68 GTO 400 With the original points distributor and it runs like new... Around 68 k miles BTW I recently asked about upgrading to the GM HEI at my GTO club Meeting the they said Keep your stock points distributor!!!

I bought my first squarebody chevy, a dually with a dump, about 400 miles from home. It had just been tuned up and ran perfectly. I drove it a good while and checked everything out well. That old 350 was running at the touch of the key and idled great. I trusted it to make it home. 60 miles in, I noticed a slight loss of power. Enough that i just got a little suspicious but kept driving. 70 miles in, while in the beltway of a major city, i was coasting down a hill and found i had nothing at the bottom of the hill. Clutch, crank, nothing! Oh no! Not here! I was able to coast to the emergency lane and safely stop. Family in minivan behind me. I got help from the finest squarbody enthusiast in the country...the ground strap had been left out from under that coil. That was a lesson i will never forget.

I'm a year older than Tony and have been in the auto industry since 1979, starting out tuning cars for large chain. 10-15 cars a day. I've tuned thousands of cars over the years. Tony hits the nail on the head here, guys. I run NOS points in all 4 of my old cars, have for 45+ years, never an issue. (GTO's and Corvette). I can't count the number of HEI failures over time. And yeah, the green wire on the module on the Olds and Pontiacs. And early GM black rotors burnt through, but the white rotors that superseded them didn't. Ran into some of the GM coil hold down screws arcing through the cap on the old 2.8 V6's. And personally have seen a handful of Chrysler BID magnetic pickup coils with cracking and no-start when hot. The new aftermarket stuff is totally inferior to the OEM 40+ year old stuff, and even then, that stuff wasn't as bulletproof as points were. Great video.

25 years ago the Wells brand ignition box for all my Jeeps would fry in a few months, so I bought all the OEM I could from junkyards. I ran out, So I converted to Ford TFI using factory 302 parts. 340 thousand miles later Tony tells it true. OEM only.

[@pauljanssen7594]

I'll just say this if you run a stock Mopar ignition system make sure you go down to Napa and get the mo 30000 rotor it gives you a closer Gap to the distributor cap with a spark goes across to the contact not shooting up because the Gap is the original cap of the old fashioned rotors. I prefer Blue streak points. And run plug wires that are not made of carbon this is another key issue you want good firepower to your plugs.

[@StevenBarton-h1x]

Mallory uniltes are fantastic! I put a dual pointy l in a 318 back in 1981.

I worked as a diehard Chevy guy at a parts store in the mid 2000’s. Used to stock a new Accel HEI distributor right on the shelf, made in Canada. I could always count on that part to give my customers a reliable conversion or replacement for HEI. They shipped that production to China, and boy did that go to hell in a hurry. I don’t know if they still make them, but Standard motor Products used to make point conversions like Petronix that were very reliable. If they are still available it might be worth a test.

I totally agree with you, I work on mainly british cars from the 50s,60s, and 70s, and I have replaced loads of dodgy electronic ignition units back to points. Mainly due to the electronic units getting too hot, resulting in the hardening of the heat sink paste and magnet brake down, the heat eventually fries the units internal components.

My son as part of his Bronco project rebuild, went with a Holly Sniper unit. Everytime he would start the Bronco it would flood out! Tracked down the issue to the new Dura Spark model he installed. It was sending false RPM data to the Sniper and flood the engine. Returned to the factory module and the problem went away. Aftermarket parts are not built to spec's I agree 💯

[@rodfonda3248]

I've realised and seen with using points , usually the rubbing block only touches the cam on one side or edge and wears quickly,so I either pull the dizzy out and look closely at the cam contact and file/sand the high spot on the rubbing block to get full contact, or you can use a marker pen on the rubbing block or cam without having to remove the dizzy

[@FastFords289]

I agree with the new parts not lasting like they use to but I will say I’ve ran a retronix conversion box in a points distributor in my old ford for years in two different engines and never had a single problem with it, never even had to readjust or anything. Perhaps the one you got was just defective or maybe it’s because mine is an old unit and it was made better. Either way something’s gotta give, we need better parts across the board.

Dr. Art poured his heart into that motor and the relevant items included along with your trans build, It deserves a close it out finally soon.

[@rhekman]

Great stuff Tony. I wholeheartedly agree, stick with the OEM design and only upgrade parts when other engine performance upgrades require it. I mostly work on either really old stuff (old tractors with points and magnetos) or slightly newer stuff from the 80s and 90s. IMHO the single best factory ignition system in terms of robustness and reliability was the Ford EDIS. They have a simple crank trigger wheel and vr sensor, no sensitive distributor pickups, no bushings to go bad, multiple coils to fire pairs of cylinders. And they're relatively cheap to repair unlike more modern coil on plug setups.

Back in the 1980's, when I had a 72 Gran Torino Sport and was building a high performance 400 for it, I wanted something easier to maintain for ignition too. I ended up converting a stock Ford single point distributor to electronic ignition using an Allison XR700 optically triggered electronic ignition kit. It worked great.

[@et76039]

Once again, great points from Tony, no pun intended. However, I do have a slightly different view on the MSD ignition, which worked well at cleaning up my overcarbureted '71 302-powered Ranchero. There is a lot of truth to Tony's view that it will cover up problems; my '71 was overcarbureted. The basic theory behind an MSD is that multiple sparks in an ignition cycle will help ignite fuel/air mixture that failed to burn properly. Given how slight imperfections will always be there, it can be a great help, but as Tony pointed out, if it helps noticeably, do try to find out what is going on. I can also see where it would clean up emissions, but many of us on here aren't very concerned with that. Probably the best strategy with MSD is to tune as best as possible with it disabled, then reenable it for reliability. I enjoyed the way it smoothed out the idle on that '71. Yep, points have a better chance of surviving solar flares and EMPs than anything electronically controlled; nothing to fry. They give you a signal before going kaput, whereas electronic ignitions generally die an instant and often unexpected death.

Tony, I agree with everything you said on ignition systems except one thing. When I was 15 I used to hang around with this kid that was 16 and had a 66 Impala with a 350/350 in it. He asked me to take a look at it because It didn't run very well. It would bog down at 2500 rpm or so, but only under load and driving down the road. After looking it over and trying to figure out what was going on with it I finally asked if it was the original motor in the car. Him and his Dad had put a 350 in it out of a 84 impala and when they were pulling the motor out of the donor car they broke the distributor cap. His Dad put in the points and condensor system from the original 350. I put the hei distributor in it and it ran perfect. The only thing I could figure out was the 84 motor had alot less compression compared to the original 66 engine. Sometimes you shouldn't go backwards with the ignition system. I've never heard of it before or since but it cured his problem with the engine. Ran good after that.
