[@jonathanking6546]

Thanks Chris, I inherited a 1969 c10 with a newer engine and couldn’t get it started. A mechanic had told the previous owner that he wanted to buy it and after looking at it the truck wouldn’t run. after watching your video you said the battery marking should say ignition. I looked and sure enough, nothing was plugged in. I hooked a jump wire to the battery and hit the ignition and it started instantly. I think the mechanic cut the wire but your video saved me a lot of headache. Thanks

[@chriscraft77022]

just remember you have an existing POSITIVE coil wire that is NOT 12 VOLTS that comes from ignition.. you need to go on the fuse box like in the video and run a NEW wire ... your truck has a place IGN just waiting for the new wire..

[@AtlantasOmStudio]

I'm not a mechanic but after watching your video I am confident enough to install my own HEI distributor -- thank you Chris!

[@christiansoldier1968]

Found this video while searching how to hook up spark advance, PCV valves, etc, then discovered I also need to watch everything this video has to offer because I'll need it again soon. Converted over to HEI in my 61 Chevy, but haven't started figuring out key wiring yet.

[@chriscraft77022]

just dont use the exsiting coil wire.. run a 12v wire.. that old coil wire is resisted down..

[@ThomasStacy-p7c]

I have a 1989 Chevrolet C 1500. I've been having so many problems getting fuel or spark from my engine. I have a 5.7 350 vortex. With the throttle body? I watch this video and I think I. Finally got some real answers, i have spoken with several mechanics, and nobody can figure it out. Thank you very much.I'm glad I watched this video.

[@Mistermopar]

Huge thanks from across the pond! I've just fitted a new motor in my '74 Nova and decided to completely rewire the engine bay. I just couldn't figure out 'BATT' on the distributor cap and bingo you've not only explained it, but given a great diagram as well! Thanks again Chris, I've just hit the Subscribe button.

[@craigrichardson8096]

Chris....thanks for the videos. I too have installed a HEI ignition in my 69 SS with a 70 LS6 engine. I am fortunate because I have a neighbor who's first assignment when he hired into GM was the HEI ignition system. I was having trouble getting my car started and he stopped by to help. It turns out when you change over to HEI and eliminate the separate coil the resistance wire is the issue. My neighbor suggested that I order a compatible (custom updated) wiring harness that has the resistance wire built into the system: has the resistance wire included in the clip into the "BAT" side of the HEI cap. The "R" post is used on the solenoid and goes into the clip. I now have no starting or charging issues. Hopes this helps others with install.

[@chriscraft77022]

that’s why I show running a new 12v wire … not using the old resisted coil wire ..so many people have thumbed this video down because they said you show running a new wire when the old coil wire can be used.. you do not use a resisted wire with HEI.. anyone that suggests buying a new wiring harness doesn’t know anything about cars or wiring..

[@craigrichardson8096]

@@chriscraft77022 Hi Chris. I did purchase a new bulk head connector from American Auto Wire at the suggestion of my neighbor who's first project when hired in to GM was the HEI ignition system. The difference was the new bulk head connector has a yellow wire that attaches at the solenoid at the "R" connection and this wire also clips into the HEI at the bat port along with the pink primary solenoid wire. But, I would like to show you what I discovered in my attempt to remedy my no crank, no start issue. I know it will help some of your subscribers who are facing the same issue with these old muscle cars. I have pics to send you if I can get your e-mail. I know you will be surprised. Stay safe.

Thank you for showing the coil to ignition diagram at 6min!! After 2 weekends of frustration and a crazy number of lame videos you came through with the needed info. 5 minutes under the dash and I'm running! Thanks again 👍😎👍

[@nbowling10trio]

Yessir, I had no desire to learn about points and how to set them. I had already been around H.E.I. so when I seen my wife's 1964 Malibu had a 1970 350ci 4 bolt main engine out of a box truck I went to junk yard and bought a HEI distributor from an early eighties Camaro and dropped it in. Super easy upgrade. Opened gap on the plugs to match Camaro which was around double. Set timing and man what an improvement. Everything got better, mpg, sound, idle, pulled harder. Excellent! Then I took the big holley off and torker2 intake manifold. Replaced with edelbrock performer rpm matching intake and 650cfm Carb. Runs great now, almost like it's fuel injected. Now I just have to get the power glide rebuilt, it's getting a little clunky on downshift.

[@chriscraft77022]

[@doginwoods]

That part you are pointing out to identify, is very important, called the "vacuum advance". It's purpose is to advance the ignition timing when you squeeze open the throttle plate. Without it, the motor will bog. But, nice vid. I'd love to build one of those pigs again. Long time!

[@BigSwipe]

I’m having this issue with a 350 Olds motor. It’s an early 70s motor installed in a g body cutlass and they used a distributor without the vacuum advance and my car drives like shit. 😁

Chris, I watched the video on installing an Hei on on Chevy. Pretty straightforward my problem is my Chevelle has been converted to msd 6al. It’s now bad. Wondering how to connect wires back to original so I can install the Hei to work properly

[@Linkys_Adventure]

I usually don't give out likes I don't know why I guess because I don't want somebody's stuff constantly in my news feeds cuz there's a lot of people who will go and take and make dumb videos back to back back to back or they're about the same stuff for repetitively after they just got through talking about it the day before and I just really can't stand that but anyway this is the best video that I have found out there on how to wire a HEI distributor I already knew how to do it but it's just been so long since I have wired one by myself that I was just looking for pointers just to ensure that I still know what the hell I'm doing lol anyway I thank you so much And you just got yourself a subscriber too by the way

[@chriscraft77022]

the main thing to know is that points ignition cars had a resisted wire to positive coil.. so you have to run a new 12v wire to the HEI coil

[@87octane2]

hey man thank you so much for this detailed explanation. i was confused on how to wire these hei units and had no idea that ignition control module was inside of the distributor itself, and you can directly connect it to the battery to test it. I am going to connect my junk yard engine this way to test it

[@rawouch]

Thank you. Just changed over th HEI on my 70 Monte Carlo and this helped.

[@chriscraft77022]

make sure you run 12v and don’t use the original coil wire it is resisted down

[@lesliemclean4381]

I have my oldsmobile setup where I can switch over to regular ignition key on start or battery to toggle switch off/on direct to the hei distributor. Since I had a broken wire from ignition switch on steering column to distributor that made the car's engine intermittenly shut off at times while driving killing power to the distributor .Makes a kool backup setup.

[@Chuncy566]

Hi ,i might not even get any answer back but,if i put a 12volt test light from the bat terminal on the distributor cap and the other lead to ground should i get a light when i turn the ignition switch on??

yes, make sure it’s 12 volts too not just turning the light on

[@SolidSnake4Ever2003]

Thx for this vid, I've always contemplated switching my spare vehicle 92 5.0 tbi firebird to carb, even after changing out literally every sensor it never ran quite right and takes a bit of cranking for it to actually start...yet in every carb vid I've ever seen vehicles instantly start up

[@chriscraft77022]

I have a 1988 5.0 TBI in my work van.. it spins over 3 or 4 times before it starts ( that is normal )... i pulled all the emissions stuff off of it and replaced everything except the knock sensor.. it runs perfect.. I would try that before putting a carb on it..

[@SolidSnake4Ever2003]

thx at least it's normal then, with a new starter put on that's about what mine takes to start too....could use a starter heat shield wrap for good measure... I actually remember hearing pulling the smog stuff off can really breathe new life into these older engines....mine still has all that crap on, I need to get me some 1 1/4th inch pipe end cover caps to plug the holes in the manifold after removing the "AIR SYSTEM" :)

[@chriscraft77022]

dont rip everything off.. plug one thing off at a time and make sure the engine runs fine with it plugged or removed.. i had to leave some egr stuff on it... make sure your battery is 100% good.. i wasted 5 hours messing with it one day and the problem was a low battery.. (it started up and ran but would run weird) the battery was at like 12 volts.. once it charged up to 13 i closed the hood and its been running perfect for 6 years now

[@lincolnbump5328]

Hey! So, I have a '74 K20. I got it running, but it didn't have much power when I stepped on the gas. I thought I needed to adjust the timing and tweak the carburetor. I started with the HEI distributor, set it to top dead center, dropped the distributor in, and put the spark plug wires in the right order. But it's still not running right, even though I know there's spark and it's getting gas. It cranks but won't fire, and now the carb is spitting gas out the top.

I had that ignition control module trouble TWICE on my '89 Caprice. But it has the STANDARD distributor, not the HEI. Those GM ignition modules don't last too long. I always buy a new one, and put it the glove box in case of it goes bad. You don't want to be stranded out there.

[@bonezcuztomz7703]

Great video I changed the distributor n still no spark

[@stevecanyon23]

Hey Chris, thanks for the video and a long question. I am about to hook up a HEI in my 1968 Camaro. I am confused as to which wire is actually the one that transmits the signal to the Tachometer. I have installed an OER repop Tic Toc Tach with the fitting printed circuit board on the back of the instrument cluster. I also got a tach filter (was recommended for use of the OER Tach with a HEI. All I have on my current engine wiring harness is apparently only for use with a conventional breaker point ignition with a coil. So, it's the braided resistance wire soldered together with a yellow one for the + side of the coil. There's also a black wire, which I presume is ground for the wiper motor. Then I have a purple one (for the starter solenoid) and another yellow wire, where I don't know what thats is for. What would be the "TACH" wire on the HEI? The "BAT" wire I believe would be a 12 gauge wire instead of the resistance wire. Hope you can give me some guidance, thanks in advance.

[@ryanmceachern3069]

Hey man, I have a 71 El Camino with a 350 small block. I don't know anything about engines. I am slowly learning off this car. I am upgrading it to a Edelbrock 4 barrel and putting a brand new HEI distributor in it. I am struggling on figuring out how to run the wires from the ignition part of the fuse box to the BAT on the distributor. I also found that there is another wire already plugged into the ignition and when I fallow the wire, it runs into another plug area with another wire that leads to another set of wires. ( sorry I don't know the correct terminology for most of this). If you could get back to me that would be super helpful since I am struggling to find any forums about my issues. Thanks and love the video.

[@chriscraft77022]

on your car you will have a resisted down wire wrapped with a cloth.. that is the original ignition wire that went to the positive side of the COIL. it goes to the bulkhead connector on the firewall under the brake booster . most of the times that wire is gone or cut out... look for that wire first..

[@ryanmceachern3069]

I am switching my distributor from one with a separate coil to the HEI. I have two wires here that were on the top of the original coil, but I had some guy tell me that they were not giving off enough voltage or one of the wires was...I can't remember, but he ended up attaching a separate wire from the back of the alternator directly to coil ontop of the new distributor in the BAT slot. The only down fall with that, is that car might not shut off. I have not tried turning the key yet because I am afraid I will not be able to turn the key. I am kind of "upgrading" my car since one of the head gaskets went out and I just recently pulled the motor to replace the oil pan since it was bent from me trying to replace the timing chain. It's all back together now up to this point. I have the distributor, Edelbrock 4 barrel, and I was hoping to add a tac to it since it doesn't have one. After I just looked I did not find any wires covered in cloth. There are about 8 wires that run from the driver side tucked in along the fire wall to the passenger side plugged into a little black box.

[@chriscraft77022]

the car WILL NOT shut off if you wire it like that.. take that wire off the alternator.. go on your fuse box (inside under the dash) and look for a spade connector by itself with IGN in white letters under it... run a temporary wire from that to BAT on the HEI... and get it started first... get a multimeter and check voltage from those 2 wires you talked about... one will have 12v when you crank and 1 will have lower voltage (6-9 volts) when IGN is on with the key.... the lower voltage wire is the original positive side COIL wire..

[@ryanmceachern3069]

Will do, Thank you so much for replying to me so promptly. I will just try and get things running before trying to get everything set.

hi why is the rotor tip pointing to the back of motor, i thought it was suppose to point to #1 cylinder thanks

[@jerrycraig6522]

Points to the #1 on the cap not the engine!!!

[@THETRUEKING12]

yup it's pointing to #6

[@brentc39]

But in the video he pointed to number one on the cap opposite of where the rotor button is pointing. It very confusing. I tried that and vehicle didn't crank but when I point the rotor tips to number one cylinder the vehicle crank but back fire through the exhaust and carburetor sometime. Some people say I have the distributor 180 degree out. Can someone help me understand?

[@Linkys_Adventure]

Well what you really do is put your finger down into number one cylinder You first remove the HEI distributor then bump start it until your finger blows off then you take a welding rod or either a coat hanger or some type of wire if you use a welding rod make sure you take all the flux off of it My favorite is the welding rod by the way anyway you get someone on the harmonic balancer to turn it back and forth until you reach TDC top dead center when you go one way and you go the opposite way for it not to move just not the least little bit then you take your distributor and you stab it in pointing it towards number one And you start timing it from there AKA putting the plug wires on at that point in the firing order sequence if you do it the way he is doing it then you wait until you find number one TDC then you look at your cap You put it on you do exactly the way I said about the welding rod and find number one on the cap and where the rotary button is pointing to and you start number one from there but like I said the best way to do it is remove distributor and find number one before you install the distributor

[@Linkys_Adventure]

Now when they're referring to 180° out you have a compression stroke and you have a fire and stroke You got to make sure you're doing it on the compression stroke that's what you start timing it from

the only time i have ever lost power was from a wire arching on the exhaust.. you say it wont start, though..

[@Ryshann]

Possibly a lost cause on a video this old, but, I have a 69 Camaro with a 350 running a HEI dis. It was always having issues running since the 20 years it sat due to that issue finally got it to run, directly connecting the HEI BATT to the battery only when firing it, but finally wanted to put it on a switch to not have it constant * we’d disconnect it once we warmed it up for a few minutes * now with the switch set up, none of the fuze terminals seem to work and let it fire up, and will short out. Returned it to wiring it off the battery and still shorts out ?! Any tips..? Seems as if the fuze box itself is just junk, electrical issues are not my space at all and would love any help If you’ve experienced anything or tips on what to test, seems like it’s the HEI but it was running 100% fine before, now going back to that it doesn’t run again ??

[@chriscraft77022]

on your fuse box run a 12g from IGN alone terminal ( the 3 in the center.. the one on the bottom) to BAT on the coil . That is all you need to power the HEI

[@daniellebrandewie2450]

Question for you. My 74 CJ5 has a key switch that the "on" position goes off when the key is turned to "Ignition" . The fuse panel is powered up via a solenoid in the "on" position, but the when turned to "Ign" the fuse panel is turned off since the "On" terminal loses connection during ignition. So in this scenario would it be correct to provide power to the HEI thru a relay in the "Ignition" position but then also provide power to the HEI thru the fuse panel when the key is returned to the "On" position.

[@chriscraft77022]

your jeep already has an ignition wire… there is no “On” Off, accessories, ign , and start … your coil is wired off ign .. you can use the old coil wire just make sure it shows the same voltage as the battery

Looking at your rotor about 7 mins in, would'nt that position be 180 degrees off from the #1 cylinder?? Or am I wrong? Thanks

[@chriscraft77022]

when you do it in real life it looks different from watching some dip shit do it on a motor stand

Great video helped me out a lot. Thanks Chris!

I had great success with those distributors often tho the mechical advance those springs and weights will actually get stuck and it will not well run right no power I've had good success with lighter springs called a curve kit it does make a difference to get advance of timing quicker .. but those distributors will run well,over 6000 rpms without a hickup,

Do tou increase the spark plug gap or upgrade the plugs now that you have 40,000 volts instead of 8000?

[@chriscraft77022]

HEI gap is .045”.plugs stay the same

Might be a stupid question,. Can I run both the Alternator Dummy Light and the Distributor BAT wire from the ignition post at the key?? 1963 c10 with an unmarked fuse block. No idea which fuse is tied to ignition so I’d like to wire strait to Key IGN but the Alt dummy light is already there...

[@chriscraft77022]

Yes, but you need a diode going to #1 on ALT... Watch my gm 3 wire hookup video

[@TheMac2781]

Chris Craft I watched your 3 wire video! Really appreciate the time you take to put these together. I inherited a truck with some crazy wiring. I’ve got the Alt diode wire hooked up to ignition post and it works just didn’t know if the distributor power wire would mess things up if i put it on the same post. Thanks again for your videos! I’m watching the Tach one next!!

[@thepals9062]

What is a tach? I took my old distributor out and dropped in an HEI but I didn’t mark where the plug was pointing to. Is that all you do is put the paper in the hole?

[@chriscraft77022]

#1 wire on cap points to #1 cylinder.. the paper ball is just to make sure you are on top dead center of the compression stroke.. in other words if the ball popped out when the rotor was pointing away from #1… the distributor would be “180 degrees off” it is actually very difficult to understand what is going on at first

[@TomVanCleave]

Can I hopk HEI to a positive ground?
