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.

There is always a reason an engine is sitting. If it was healthy and made big power it would be in a car. People don't let too many high-performance engines sit around guys. Great video 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.

This is how it is in Germany. Dude drives a pos 1980 Parisienne Wagon with high jackers and a 350HP 350 - I mean, it has a Holley carb and cherry bombs! smh
At least it was actually rebuilt... could have been an old motorhome engine with 100K on it and the only thing keeping the rods from knocking is the 10 pounds of sludge in the crankcase.
That was my thought too. A set of dome pistons should bring that engine to life. Annoying to have to tear down the engine again but not a huge deal with it being out of the car when bought.
@TheMEXICANBEEF Avoid the hassle set the timing 42 btdc buy some MOROSO octane booster if you can still find it if not go to your chemical supply house and get some aniline oil just don't get it on you,you'll get dizzy fall down and die of respiratory arrest,mix that one quart to 10 gallons of 93 octane,hell throw a gallon of toluene with that too,you may even want to try different mixes with e-85 get that virtual compression ratio up and then you'll have a rompin stompin wamma jamma untill it goes bye bye,poof!
It's like my electronics instructor told us at the beginning. "You will spend more time fixing what others have messed up than fixing the original problem". After 40 years in automotive maintenance he was proven right over and over. A little knowledge is a dangerous thing.
Can't stand when someone monkeyed with float level because it's not running right , and you end up finding the real problem , and then have to fix the float level. Keep the paws off the float level!
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.

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.

Used engines are like a box of chocolates, you just don't know what your're going to get. Great episode and take care. Didn't forget the cannoli and espresso.
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.
So good to see that you're training the next generation of classic muscle car mechanics like Vassily. I'd also love an update on Vassily's girlfriend's race car performances.
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. As President Reagan used to say, "Trust but verify."
Back when I was in the Air force I ran into a similar deal. A man had a 396 SS chevelle. He rebuild it and it would not turn completely over. He thought about towing it and decided to ask my opinion. Well I went to his home and we removed the heads. The pistons were 12.5 to 1 and were installed wrong and we also found a rag left in under the intake. 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. When the work is hard and the wages are low take you time and go quite slow. Lol.
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! 👍👍
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.
Back in the day I've turned some 4 valve relief 302 pistons backwards. Since most don't know if it has an offset wristpin instead of centered it will pull the piston further and hang at tdc longer. Worked flawlessly for years! This was not the case for this 454!!!! The 302 had 200lbs compression and made around 400hp with junky iron heads lol!!!!
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 😳
I pat myself on the back with this one. When you made that dyno pull, knowing it had those big M, big port heads, I knew it had flat tops in it. Upside down none the less lol! I'm a Chevy man through and through and had a few Big Blocks and many, high revving small blocks.. Gear Drive = Valve Train Vibrator.
Always fascinating to see a master of his craft at work. The Experience really shows. To often today people never seek to achieve that level of Awesome.
Take the little stainless rectangular cap off the door and or trunk lock and you will see the spring loaded brass pins that are different lengths. These are what the key pushes up to make the lock able to turn. I had extra Mopar locks from junkers and swapped around the pins so I had a one key Fury.
One place I worked the boss had a TOP NOTCH ENGINE BUILDER assemble his marine 454 Chevy's. The top notch tech the boss's friend was putting the rod caps on backwards.
Heh heh, engines like this 454 crack me up! I had a customer back in the mid-80's that bought a pretty nice looking '66 Fairlane with a supposedly 'built' 302. Poor guy couldn't seem to get it past 4200 without breaking up, and after changing out the coil, spark plugs, new carburetor, etc., he finally brought it to me to see what was going on. It sounded great at idle. Nice lumpy cam, roller rockers hiding under pretty chrome valve covers... *on top of stock worn out Ford valve springs and retainers!* It had *maybe* 100 lbs. of compression across the board, and I notified the owner, and he said to pull the engine and see how bad off the rest was. The cam and lifters were probably the best part of the whole engine, along with an antiquated Mallory dual-point distributor, and an almost brand-new set of Hedman Headers. The rest of the engine was essentially bone stock, with typical small port 302 heads, and stock pistons. We ended up using it for a core and got a 347c.i. long-block (stroker crate motor), equipped it with late model ECC IV electronic ignition and a high output coil, and turned that sickly Fairlane into a 370 hp. tire melter that still got fairly decent gas mileage. Not too bad for around $2500 back in the day.😉
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.
While it was a 454. It still had the factory heads with hand port job. Motor was rebuilt by DRE with his custom hydraulic roller, flat top piston with 10.1 cp and made 606hp on pumped gas with no timing really in it. Soft tune. You can make power when it's built correctly. This video shows what happens when people don't have a clue. I mean really. The pistons installed upside down is just ridiculous.
Good thing that was a small cam with the intake reliefs on the wrong side of the cylinder. Bad juju when pistons kiss valves. Hopefully the 427 owner wants to pony up and have Nick build that 427 right. Be awesome to put those heads to work!
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 .
If I remember correctly the base 427 in 1967 was 390 hp. This was a mild street able engine used in Impalas, Corvettes etc. it used hi test leaded gas. Using the flat top Pistons would allow today's regular pump gas. I think the geared cam may also be ground to turn the other way unless it has idlers like the old Jackson setup. This engine is a mess of incompatible parts.
Just found this channel! So glad I did, this is excellent content that is much appreciated! I will like every video I see without a doubt. Great tear down and keep the details and length it is thorough and awesome 👌
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.
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.
Honestly how hard is itbbto put pistons in the proper way round im, no expet but have put a few donksbtogether all i do isvread and follow all the instructions properlyand thisnnwas b4u tubeb or watever
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!!
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
@@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.
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.
Looks like that big block Chevrolet needs a PROPER fresh rebuild by Nick and crew from the bottom up. I know you guys can make that engine really sing if the customer asks you to do it. I think 550 horse is a more realistic goal for horsepower on just pump gas, but I’m not an expert. Take care of that bruise above your eye Nick, a couple extra breaks with a nice Chocolate drink should do the trick! Thanks for another great video! Love that beautiful orange Road Runner!
The pistons being installed wrong is what I noticed my late dad used to do when he built an engine. Which he used to tell me when I was a younger person, that is what made more horsepower and torque. Needless to say I found out later on in life that he was full of bovine excrement. Since I had a friend named Bob the Engine Professor who built engines for 40 plus years when I was a younger adult learning about engines, show me on his Dino that it backfires through the carburetor and possibly could bend valves. So in his own way he stated the same thing that Mr Nick the Engine Man is talking about in these videos.
I have heard of this too, but the trade off is pistol stability. Pistons installed 180* rotated will cause piston slap because of the piston pin offset. In this case, installing the pistons rotated 180* was not going to make significantly more power. Flat top piston plus open chamber heads equals low compression. I don't know what the builder was thinking with this one.
If you had a stock type/4 valve relief piston back in the day, and were racing it, it was normal to reverse the pistons to increase the dwell at top dead center. The factory engineers offset the piston pin to reduce piston slap (knocking) on cold starts, and to prevent skirt breakage with fragile cast pistons. It WAS hard on pistons, Racers threw them out after a couple of hundreds laps, few weekends at the drags. The more you know the more you grow.
Was just noticing that! The focus is incredible, if you look close he doesn't even blink while watching the run up! Those eyes have seen everything lol
I love 1970 RR>X they are the most beautiful cars Plymouth ever made. The trunk wing is a distraction to the beauty of the Hemi Bird. My friend has a 2001 Prowler with a 2005 LS3 it is the sleeper from Hell. Beautiful also.
First of all, it's a tall-deck block, 10.200" deck height, probably from a dump truck. Flat-top pistons with Merlin heads, he lucky if it has 8-1 compression. The fact that the pistons are upside-down, and the intake valves aren't hitting says something about the cam, and that it's not very much. There's probably a lot more wrong with it, and Nick will find out once he sees the entire engine. I don't know why people don't do a bit more research before spending money on an engine build. We see a lot of this at our shop as well.
@rollydoucet8909 for arguments sake, if you have a 427 TD truck block, with the right combo of parts, a sonic checked block, and a lot of time clearancing the crankcase fmor stroke, there is the potential for a roughly 550 cubic inch combo. But there are much more cost-effective ways to do it. Especially with how inexpensive some of the aftermarket stuff has gotten, by the time you consider how much screwing around you gotta do to make that combo work.
I don't guess when it comes to horse power , I ran my 68 super bee with a 440 on a chassis dyno back in 69 with cam headers holly 780 I got 325 hp at the rear wheels never guess that's what Dyno's are for !! Good Job Nick !! another 5 star video

The fact is, it's such an easy thing to build as engine properly. Careful attention to detail is what it's all about even before a torque wrench comes into play!

That was my thought too. A set of dome pistons should bring that engine to life. Annoying to have to tear down the engine again but not a huge deal with it being out of the car when bought.
@TheMEXICANBEEF Avoid the hassle set the timing 42 btdc buy some MOROSO octane booster if you can still find it if not go to your chemical supply house and get some aniline oil just don't get it on you,you'll get dizzy fall down and die of respiratory arrest,mix that one quart to 10 gallons of 93 octane,hell throw a gallon of toluene with that too,you may even want to try different mixes with e-85 get that virtual compression ratio up and then you'll have a rompin stompin wamma jamma untill it goes bye bye,poof!
At least it wasn't a krylon rebuild with it paint it ship it lol
I prefer the 454's out of motorhomes. I build them for demolition derbies. Even the hated peanut port heads work great for a torque build.
It's like my electronics instructor told us at the beginning. "You will spend more time fixing what others have messed up than fixing the original problem". After 40 years in automotive maintenance he was proven right over and over. A little knowledge is a dangerous thing.
Can't stand when someone monkeyed with float level because it's not running right , and you end up finding the real problem , and then have to fix the float level.
Keep the paws off the float level!
Right. He come fix this job some fawked. Up. Ok. That gonna cost you double. I have to undo someone else fawk up and do over again.
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.

Glad to hear you didn't get hurt too bad Nick - everyone would really miss your videos. Good thing us old time hot rod guys are tough! Keep the faith and keep building good lumps!!!
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.
That guy got ripped off! Man I like that roadrunner
Thanks Nick and of course George the Super Camera Guy...WOW how good is he..... For the...update video...!

That 70 Road Runner brings back a lot of memories. I bought one when I returned from Southeast Asia in 1970.
You guys are a joy to watch. To the point and simple language. A lot of these videos are more talk than do. Glad I found you guys. Keep up the great show.....
Mr. Thank you.
If you want to know the truth bring it to Nick's garage. If you want it to run right and make the right horsepower bring it to Nick He's the man. when it comes old school Great job, Nick, and that's a beautiful Road Runner. I can't. Going down the road. Be safe.
A 427 chev. My dad had a 65 Strata Chief. That was the name I recall. 4 sp. Some fella bought it new and drag-raced at a local track in New Brunswick. Dad redid the engine and a decal remove. When done, it never looked like the tiger it was. The 3 pedals and the Hurst button for the brakes was the only give-away. Cheers! and Thank You.
Nick shall bring the power forth. Nick bumped his head and made the flux capacitor.
But not with those pistons, maybe not the cam either. I dunno, this engine build looks more like lipstick on a pig rather than a serious build.
THANK YOU NICK, I HAVE LEARNED SO MUCH FROM YOU, YOU WILL NEVER KNOW, I WAS TAUGHT BY MY FATHER, KNOW I KNOW HE DID A MICKEY MOUSE REPAIR, BUT WATCHING YOU, HAS BEEN A LEARNING EXPERIENCE, AGAIN, "THANK YOU".
I love watching videos like these. They're mesmerizing because I don't understand one thing Nick is trying to explain but just the same, "oddly satisfying".
Great to listen to Nick, very knowledgable and fascinating to watch,. An education...
I'm from a little town in United States called Taft, California. I love watching your videos. Please keep your videos coming and I will continue to watch them. Have a nice day. Nick

Nice work nick on that orange bird
Used engines are like a box of chocolates, you just don't know what your're going to get. Great episode and take care. Didn't forget the cannoli and espresso.

Tha car that cut Nick's eye AUTOMATICALLY gained 40hp!👍🙏
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.
Mike. So one of two marine engines is all backwards. Interesting. Thanks for the info Mike.
Hope your eye heals quickly! Another great Monday Morning with Nick's garage.
I’m seriously in lust with that Road Runner!❤️❤️❤️
So good to see that you're training the next generation of classic muscle car mechanics like Vassily. I'd also love an update on Vassily's girlfriend's race car performances.
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. As President Reagan used to say, "Trust but verify."
didnt happen...
Thank you for addressing my question from your first live stream in this video. 70 roadrunner only runner up to my favorite the 71.
Thumbs up! A true professional.
Being such a perfectionist Nick is why your cars come out so Brilliantly. You and your team turn out perfect product. Little Aussie Follower ....
Thanks Nick! Good video on the Missing HP.
Wow that’s hard to watch as an engine builder I just wanna see that Big Block Chevy built correctly with the right combo and back on the dyno 🤦♂️
Hi Nick and to all! 12.15 am here in Melbourne Australia and the coffee’s hot.....enjoying your channel!
Good morning! Thanks Mario.
Good morning sir. Hope you have a good day!
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.
Back when I was in the Air force I ran into a similar deal. A man had a 396 SS chevelle. He rebuild it and it would not turn completely over. He thought about towing it and decided to ask my opinion. Well I went to his home and we removed the heads. The pistons were 12.5 to 1 and were installed wrong and we also found a rag left in under the intake. 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. When the work is hard and the wages are low take you time and go quite slow. Lol.
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! 👍👍

Realty always bats last.
This is good stuff,thanks.
I never fail to learn something important with every episode. Cheers, Nick!
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.
herman. That is the way to do it.
Back in the day I've turned some 4 valve relief 302 pistons backwards. Since most don't know if it has an offset wristpin instead of centered it will pull the piston further and hang at tdc longer. Worked flawlessly for years! This was not the case for this 454!!!! The 302 had 200lbs compression and made around 400hp with junky iron heads lol!!!!
Dodge engines like the piston flip too
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 😳
I pat myself on the back with this one. When you made that dyno pull, knowing it had those big M, big port heads, I knew it had flat tops in it. Upside down none the less lol! I'm a Chevy man through and through and had a few Big Blocks and many, high revving small blocks.. Gear Drive = Valve Train Vibrator.
Always fascinating to see a master of his craft at work. The Experience really shows.
To often today people never seek to achieve that level of Awesome.
Take the little stainless rectangular cap off the door and or trunk lock and you will see the spring loaded brass pins that are different lengths. These are what the key pushes up to make the lock able to turn. I had extra Mopar locks from junkers and swapped around the pins so I had a one key Fury.
Thank you for making the keys right. It drives me nuts when the keys do not match like they should.
One place I worked the boss had a TOP NOTCH ENGINE BUILDER assemble his marine 454 Chevy's. The top notch tech the boss's friend was putting the rod caps on backwards.
I remember testing the compression on my 1969 BelAir 427, 425HP in early 1970. It blew up my compression tester.
Heh heh, engines like this 454 crack me up! I had a customer back in the mid-80's that bought a pretty nice looking '66 Fairlane with a supposedly 'built' 302. Poor guy couldn't seem to get it past 4200 without breaking up, and after changing out the coil, spark plugs, new carburetor, etc., he finally brought it to me to see what was going on. It sounded great at idle. Nice lumpy cam, roller rockers hiding under pretty chrome valve covers... *on top of stock worn out Ford valve springs and retainers!* It had *maybe* 100 lbs. of compression across the board, and I notified the owner, and he said to pull the engine and see how bad off the rest was. The cam and lifters were probably the best part of the whole engine, along with an antiquated Mallory dual-point distributor, and an almost brand-new set of Hedman Headers. The rest of the engine was essentially bone stock, with typical small port 302 heads, and stock pistons. We ended up using it for a core and got a 347c.i. long-block (stroker crate motor), equipped it with late model ECC IV electronic ignition and a high output coil, and turned that sickly Fairlane into a 370 hp. tire melter that still got fairly decent gas mileage. Not too bad for around $2500 back in the day.😉
@Paradoxical Nightmare LOL, no doubt!😁
The phrase "sold a bill of goods" comes to mind with that 427. Can't wait to see what you guys do with it!
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.
While it was a 454. It still had the factory heads with hand port job. Motor was rebuilt by DRE with his custom hydraulic roller, flat top piston with 10.1 cp and made 606hp on pumped gas with no timing really in it. Soft tune. You can make power when it's built correctly. This video shows what happens when people don't have a clue. I mean really. The pistons installed upside down is just ridiculous.
Good thing that was a small cam with the intake reliefs on the wrong side of the cylinder. Bad juju when pistons kiss valves.
Hopefully the 427 owner wants to pony up and have Nick build that 427 right. Be awesome to put those heads to work!
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 .
well the guy that put that 427BBC together didnt know what he was doing....great video
If I remember correctly the base 427 in 1967 was 390 hp. This was a mild street able engine used in Impalas, Corvettes etc. it used hi test leaded gas. Using the flat top Pistons would allow today's regular pump gas. I think the geared cam may also be ground to turn the other way unless it has idlers like the old Jackson setup. This engine is a mess of incompatible parts.
Just found this channel! So glad I did, this is excellent content that is much appreciated! I will like every video I see without a doubt. Great tear down and keep the details and length it is thorough and awesome 👌
Working Class. Thanks for enjoying our channel.
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.
Great job, Nick
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.
It is a good thing those flat top pistons didn’t have the compression height to strike those valves.
outstanding!!!
looking forward to the rebuild
The Road Runner is gorgeous!
Honestly how hard is itbbto put pistons in the proper way round im, no expet but have put a few donksbtogether all i do isvread and follow all the instructions properlyand thisnnwas b4u tubeb or watever
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!!
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
you can make 600Hp with oval port heads. Those heads are way to big as is the intake and carb.
I bet you could wire that Dominators secondaries shut and still make the same HP.
@@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.
I love when guys say rectangle ports are not good street heads 😂
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.
Looks like that big block Chevrolet needs a PROPER fresh rebuild by Nick and crew from the bottom up. I know you guys can make that engine really sing if the customer asks you to do it. I think 550 horse is a more realistic goal for horsepower on just pump gas, but I’m not an expert.
Take care of that bruise above your eye Nick, a couple extra breaks with a nice Chocolate drink should do the trick! Thanks for another great video! Love that beautiful orange Road Runner!
The pistons being installed wrong is what I noticed my late dad used to do when he built an engine. Which he used to tell me when I was a younger person, that is what made more horsepower and torque.
Needless to say I found out later on in life that he was full of bovine excrement. Since I had a friend named Bob the Engine Professor who built engines for 40 plus years when I was a younger adult learning about engines, show me on his Dino that it backfires through the carburetor and possibly could bend valves.
So in his own way he stated the same thing that Mr Nick the Engine Man is talking about in these videos.
I have heard of this too, but the trade off is pistol stability. Pistons installed 180* rotated will cause piston slap because of the piston pin offset. In this case, installing the pistons rotated 180* was not going to make significantly more power. Flat top piston plus open chamber heads equals low compression. I don't know what the builder was thinking with this one.
@Camp'n Outdoors Sounds right.
Right or wrong you don't disrespect your Dad, what's wrong with you? He didn't smack you with a hammer enough times..
If you had a stock type/4 valve relief piston back in the day, and were racing it, it was normal to reverse the pistons to increase the dwell at top dead center.
The factory engineers offset the piston pin to reduce piston slap (knocking) on cold starts, and to prevent skirt breakage with fragile cast pistons. It WAS hard on pistons, Racers threw them out after a couple of hundreds laps, few weekends at the drags.
The more you know the more you grow.

Great Job on The Diagnosis and Teardown Nick n Vasili 🧰👨🏼🔧😎😀👍🏼
Nice job looking forward buddy. Interesting video. Thanks guys
Nick and garage are the best!!!
First of all, it's a tall-deck block, 10.200" deck height, probably from a dump truck. Flat-top pistons with Merlin heads, he lucky if it has 8-1 compression. The fact that the pistons are upside-down, and the intake valves aren't hitting says something about the cam, and that it's not very much. There's probably a lot more wrong with it, and Nick will find out once he sees the entire engine. I don't know why people don't do a bit more research before spending money on an engine build. We see a lot of this at our shop as well.
I mean.. if you're gonna run a 10.2 deck big chev, you might as well come out swinging with 632".
@@HerculesRockefellerESQ A Chevy truck block cannot be worked into a 632. Bores are too small.
@@rollydoucet8909 it was a tongue in cheek remark. If you're gonna run a tall deck, might as well make it count.
@rollydoucet8909 for arguments sake, if you have a 427 TD truck block, with the right combo of parts, a sonic checked block, and a lot of time clearancing the crankcase fmor stroke, there is the potential for a roughly 550 cubic inch combo. But there are much more cost-effective ways to do it. Especially with how inexpensive some of the aftermarket stuff has gotten, by the time you consider how much screwing around you gotta do to make that combo work.
Your a good man nick
I don't guess when it comes to horse power , I ran my 68 super bee with a 440 on a chassis dyno back in 69 with cam headers holly 780 I got 325 hp at the rear wheels never guess that's what Dyno's are for !! Good Job Nick !! another 5 star video

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.
My thoughts exactly! Those bores look awfully small, and the spacing/meat between them looks thicker than usual. I'm not am expert though
The fact is, it's such an easy thing to build as engine properly. Careful attention to detail is what it's all about even before a torque wrench comes into play!
