When I purchase engines from anyone in the private sector, I use a cheap bore scope that hooks to my phone. It will tell you if a engine has flat tops, you can easily look at the valve train, you can check to see the bottom end, or see if a engine has four bolt mains (if that's the claim). It's quick and easy, and if the seller doesn't want to let you investigate well that tells the whole story anyway. Another great video Nick thanks.

Now the fuel he told me was good for extremely high altitude flight,the three key components: first was a thing I think he was mumbling to protect secrecy it sounded stupid furfall alcohol,second hydrazine, third aniline oil to control burn-rate,he was retired and had 2 hobbies fishing and flying his P-51 Mustang,he was a great man loved to listen to his stories.

I guess this shows that it’s really hard to not make some power with a BBC. Low compression, tiny cam, big rectangle port open chamber heads, and a single plane and it still made 366hp. It literally had everything working against it. A set of closed chamber oval ports and dual plane and it’d be a nice torquey motor. Dome pistons and a bigger cam and it’d be a fire breather. Either way and perform way better than when it arrived.

[@mikeakerman768]

I did a 454 for a farmer's truck one time, it came in with a very slight rod ticking. So o tore it down resized the rods at machine shop. When installing them one piston was on rod backwards. Had to take it back to be pressed off and turned around. If I wouldn't have caught it . It probably wouldn't make 100 miles without ruining crank and who knows what else. You have to stay focused. Not everyone can throw it together. Good job Nick.

[@vhp454]

Gear drives on a bbc is a no no. There only good to 6000rpm, a double roller chain or belt drive is much better ! Check the cam also , some people have no clue about engines or BBC. A 427 L-88 revved easily to 7200 and had 7/16 pushrods not 3/8. And GM bbc square port heads can build 600 hp very easy. A Edelbrock dual plane rpm intake works well. 850 cfm holley is also a good choice. Try using a first design L-88 solid lifter cam. Get compression up to atleast 11.0 valve springs need updated also.most of this and good machine work should wake the dead out of it, but you are the man Nick. Love your channel Nick

I disagree. Most budget builders will do their builds in stages. They either build the engine first or build the car. Life happens, things change, health fails. This is even more so for people on a strict budget. That window gets bigger because vudgets are smaller and is more prone to life disruptions. Mistakes are made from ignorance and not doing homework and desperation to complete the job. A flipper sellsa fresh engine with cheap parts. Not an engine just sitting for awhile.

[@mikepotter5071]

We used to have a standard rotating engine and a counter rotating engine in boats. The screws have to turn outboard of each other or the boat will run terrible. Chrysler got out of Marine. GM and Ford stopped building counter turning engines. Marine gear builders picked up the counter turning screw in the gear. Chris Craft used gear to gear with their counter turning chevys. The lobes on the cam were ground to provide 12756348 firing order. The pistons in small blocks were put on the rods backwards to compensate for the outboard piston skirt beating on the walls. Big blocks could not do that because the valves hit the pistons. Closed chamber heads were used. Breathing is not the thing in Marine. Long stroke low rpm is. Other differences included reverse ribbing on front and rear main seals. Standard ribbing on a reverse engine will suck the oil right out. Chrysler used slashes on the rear seal surface for the cranks. That had to be machines backwards too. Starter drives engaged backwards. Their drive teeth were machined backwards. Fields wound to spin backwards. I was there, that’s how it was, that’s what I got to say about that.

Those heads are made for a radical cam, high lift rockers and 12 to 1 compression with a short block capable of turning at least 7500 rpm. This is not for a stock BB short block with those tight main bearing clearances. Cheapest is to put some good cleaned up stock oval port heads with a good valve job, a good aftermarket chain and sprocket and a more realistic manifold that will give more low lift flow.

Couple decades ago, I bought a Mopar 383 engine that had been bored .040 and stroked with a 440 crank that had its mains turned down to 383 size. Made it 434 cubic inches. Complete engine, supposedly ready to go. I put it in my car and fired it up. Ran OK at first. Added coolant to the radiator, then had to again, and had to again, then the engine seized. Suspicious of having to add so much coolant, I pulled the oil pan drain plug. Bunch of coolant ran out. OK, pulled the motor, took it completely apart. Found out that the 440 crank's counterweights (bigger than 383 counterweights) had hit the block and the builder (who shall remain nameless) had ground the block for clearance and gone into the water jacket, then tried to plug the leak. Obviously he didn't pressure check the attempted repair. Fortunately the seller (he wasn't the engine builder) agreed to pay for the machine work on an extra 383 block and 440 crank I had in my parts stash (the proper way to make it fit was to cut the 440 counterweights to 383 size). Then I assembled the motor myself. Still running today after almost 20 years.

A friend of mine had a BB Chevy custom built for his street racer '70 Camaro. Took the engine straight to a dyno man like Nick's customer did and it too didn't make horsepower. Turns out the engine builder was doing two BBs at the same time. The other one was for a truck to haul the customer's boat requiring a completely different engine. In the build process some parts got mixed and neither guy got what he wanted. The builder made things right on his dime so everything turned out OK in the end.

One of the biggest electrical issues with classic Mopars is the ignition power wires, to and from the switch, are very long. The wires increases in resistance over time , the connections get old and develop resistance and the contacts in the switch wear and increase in resistance. This can cause a drop in voltage to the ignition system and throughout the ignition system.

He reinstalled the pistons correctly and removed the rag put it all back together and it run fine. No one is perfect and hast makes waste.

[@SealofPerfection]

I would say Merlin heads are probably too big for a street 427 unless it's a high revver. World makes some Merlin oval ports that would easily produce that 600hp number and more torque for the street with the right compression and cam. Edit: Upon watching this again, that's a tall deck block. So someone slapped some big port heads on a tall deck block. Okay, but you have to have the right pistons for it. I wonder if someone put short deck pistons in it as well? They are awfully far down in the hole. STROKER ENGINE TIME!!

[@modelnutty6503]

yup, similar thoughts. its assembled wrong for starters, piston+rings on wrong, wrong intake.. 366 ponies should be a bit higher, but the 125 compression range (lower ratio) could be good for normal driving, spraying when you want big power

[@stanherman5604]

you can make 600Hp with oval port heads. Those heads are way to big as is the intake and carb.

@@modelnutty6503 Yeah, you don't know what you're talking about either. Probably, friends with the guy that built that motor. The 125 figure that Nick found was a cranking compression test in POUNDS using a compression tester. Nothing to do with compression ratio. While I would like to see around 140-160+lbs, it's more important that all cylinders are within that 5% number. If there are 7 cylinders showing 150lbs and one cylinder showing 125lbs, there is most likely a problem there.

Well the good news is that all it should take is a new set of pistons and a new cam to get where he wants (and better valve springs, etc. to support a higher lift cam because the ones that are in there obviously can't support the lift of that small cam). Seems pretty obvious that whomever put that engine together didn't do the math up front to get the right components to get their compression ratio where it needed to be. I'll bet they didn't even measure the combustion chamber volume of those heads. Which, seeing how the pistons were put in backwards, doesn't surprise me.

[@billcat1840]

I used to make a killing fixing screw ups like this. Many people don't have an understanding of how the parts must work together and compliment each other.

[@permagrin8742]

used to be a mod to stop power valve issues. you gave a passage seat a mark with a phillips screwdriver to put a cross mark in it, then you put a small bearing in over it. apparently if a back fire happens, the ball gets pushed into the seat, but the X mark you made keeps it from sticking in place?

Thumbs up! A true professional.

[@niceguy2171]

Wow, the things you find when you dig in an engine, 105 and 115 Cyl. compression, seen old lawnmowers do better than that,lol. Watch the overhead objects Nick, you don't need anymore knocks on the noggin' ;) Hope all is well in the shop on this fine day.

[@gadget73]

Thank you for making the keys right. It drives me nuts when the keys do not match like they should.

[@mackbruce7545]

Not too worry. Here at Nick's Garage /GYM. He will get this BBENGINE pumping out the horse power.again. Good luck thanks for the videos. Watching from Wyoming.

[@edstransitscott9186]

Great job, Nick

[@MontrealMan1970]

Good time to brush-up on your chevolet big block i.d. numbers. Make sure you didn't get a truck 366! and ditch those hideous valve covers.

[@grabasandwich]

My thoughts exactly! Those bores look awfully small, and the spacing/meat between them looks thicker than usual. I'm not am expert though

[@twlvhrs]

Very informative and exciting for me to watch, there are so many car guys out there that think they know what they're doing, till something goes wrong, Love these videos, Thanks Nick :-)

Hey Nick put a blower on top of that motor and make WAY over 600 HP. At 120 per cylinder thats right at somewhere around 8.5 to one. Ideal compression ratio for a blower putting out sub 25 psi on street premium gas. My last performance motor was a 355 SBC with a 144 B&M blower that made close to 450 without the NOS that boosted it to over 600HP. That was out of a 355 SBC. A 434 big block with a 6/71 or paxton setup should be close to 800 if not more without NOS. That is if the pistons are good forged ones, rods are good aftermarket, 4 bolt main block and a steel crank. Otherwise you are making a BIG grenade. Would make for a great KZbin video of dyno disaster segment however if cheap parts are used.

It's nice to see people caring about what they do! I subscribed instantly. Keep up the good work. -Glen

[@jamesrogers5783]

its been a while, but i built a few of these that made 600hp and change with the small 2.19/1.78 valves and a solid flat tappet., we did have some good compression numbers from those 12.5 pistons right out of GMs racing bible of 1980 !!

[@neilmacleod5371]

I had a duster , and the start key did not work in the door , door key was the same as the truck key . The car was bought off the showroom floor brand new .

[@nickpanaritis4122]

Niel. Something wrong there. Never seen or heard of this issue on a Chrysler product.

[@neilmacleod5371]

@@nickpanaritis4122 i also had a valient bought brand new , 273 v-8 ( I think the slant six in the duster was faster ) and it was the same way starter key was the big key , the doors and trunk were the small key , worked good if you want to warm the motor up on a cold day , you could lock the doors and still have the engine running , wasn't a problem , it's the way the cars came in . Both were bought off the showroom floor

[@knunyabeasewhacks8744]

The small valve springs was a give a way, but the installing the Pistons with the mark "backwards" is a tell tale sign of a unexercised build.

[@stevemitchell2252]

Nick and garage are the best!!!

[@tomhurley974]

always enjoyable to share some time with nick

[@yodaistheone]

I Love how you say fix it right. I Repair tachographs.....and i always have to repair other people's fixes before i can actually repair the original faults that caused the instrument to fail .

[@rodneybrand8521]

Hey Nick..being a tall dude at 6 .1' i have to watch low objects myself and I've hit a few things too..isn't any fun.hope you didn't damage the axel..lol..that's bad about the big block chevy..some people should at least ask someone who knows about them before they tear into them .. it takes a lot of money to make a big block produce 600 hp..i noticed the pistons are flat top..shouldn't they be high domes ? I had a 69 chevelle 396. 350 hp when i got through it was pushing 425 hp it cost me 1.600 to bump it up that much in 1976 that was a chunk of dollars for me .. but she would do it i was very pleased..that 70 roadrunner is sweet wish i had it..whoever ownes it is going to be very happy with it..beautiful car and a performer as well.. ok Nick see you on the next one and don't forget to duck...lol..Cheers 🍻🍻🍻🇺🇸🇺🇸🇺🇸

[@jasonwood7340]

@Aaron Cubitt Taller than average height of most countries. I'm 6'3" and I hit my head on stuff sometimes. Most stuff isn't constructed for "tall" people. A hat helps cushion the head for sure =)

[@bigmountain7561]

Poor thing is a Boat Anchor. 600 hp with 115 in the cylinder. Someone is smoking something!!!!! Hey Nick to you work on VW TDI’s???

[@nickpanaritis4122]

Joe. VW TDI's. No, not really.

[@GeekBoyMN]

The phrase "sold a bill of goods" comes to mind with that 427. Can't wait to see what you guys do with it!

[@Uppercut314]

What amazed me was, hearing that seeing the pistons were installed 180* off! It’s a wonder the valves made it through the combustion process without major damage! WOW 😳

[@kramnevets8712]

“And see the truth” Realty always bats last. This is good stuff,thanks.

[@mikeasions7754]

Absolutely love your videos Nick. I learn something new every time... Nick, my curiosity is getting the best of me...what is the Milwaukee tool case doing on the milk crate by the engine exhaust vent fans in your dyno room? Take care Nick....

[@hensleyshobbies-doug7761]

That’s a darn shame about that Big Block Chevy 427, but that just goes to show you some guys are not the mechanic that they think they are! Geez! It’s a good thing that customer brought it to you Nick, I know you’ll get that big Chevy lined out and doing what it’s suppose too! 👍👍
