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.

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

[@stlchucko]

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 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.

[@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.

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.

[@graymodeler]

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.

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.

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.

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.

Besides the fact that the pistons were installed wrong, did you check deck height? Luckily the cam is small and the intake valve apparently didn't hit the piston.

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.

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.

@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.

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! 👍👍

[@Shane-Singleton]

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.

[@RedEyedPatriot]

Can't wait for the new pistons and cam...nick will have that BBC pushin 5to600 soon

[@jonathanbarnes9411]

427 tall deck. Lol, saw that a mile away.

[@grabasandwich]

Was it the small bores?

[@SealofPerfection]

@@grabasandwich Bores have nothing to do with it. A 427 TD has the same bore as a short deck or a 454.

[@grabasandwich]

@@SealofPerfection I meant if it was a 366 which apparently has smaller bores. My bad.

[@crankysports]

Hope your eye heals quickly! Another great Monday Morning with Nick's garage.

[@mariorabottini5687]

Hi Nick and to all! 12.15 am here in Melbourne Australia and the coffee’s hot.....enjoying your channel!

[@NicksGarage]

Good morning! Thanks Mario.

[@TheSleepyMechanic0524]

Good morning sir. Hope you have a good day!

[@oo-dd3lk]

Great to listen to Nick, very knowledgable and fascinating to watch,. An education...

[@91rss]

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?

[@thomasjefferson2938]

Thank you for addressing my question from your first live stream in this video. 70 roadrunner only runner up to my favorite the 71.

Thanks nick, always nice to see your expertise in action. Amazing what thieves are out there. Keep up the good work!

[@MrAntoniocain]

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.....

[@nickpanaritis4122]

Mr. Thank you.

[@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!

[@markwallace5274]

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 🤦‍♂️

[@GeoHvl]

I love 1970 RR&GTX 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.

[@Pgcmoore]

outstanding!!! looking forward to the rebuild

[@daviddntait]

Maybe it had 600hp with a 6-71 blower on top!? After all it did have flat top pistons to lower compression. I've put fla tops on purpose for that exact reason. Doubt that was the reason for this particular 427. At least they knew enough to put Merlin heads on it haha!

[@kurtpoblenz2741]

Underpowered & big block Chevy always go together 😂😂😂😂

[@darylnicklen3685]

Being such a perfectionist Nick is why your cars come out so Brilliantly. You and your team turn out perfect product. Little Aussie Follower ....

[@spurgear4]

Same as my 69 340 Swinger. 1 key for the ignition. 1 Key for the doors. And a key for the trunk. Someday I will get to it, maybe...

[@MrJeffcoley1]

It is a good thing those flat top pistons didn’t have the compression height to strike those valves.

[@TheCrewChief374]

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.

[@michaelstansfield319]

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.

[@dukeman7595]

@Camp'n Outdoors Sounds right.

[@dukeman7595]

Right or wrong you don't disrespect your Dad, what's wrong with you? He didn't smack you with a hammer enough times..

[@robh9577]

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.

[@dukeman7595]

@@robh9577 That's a fact..

[@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 :-)

[@gadget73]

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

[@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 !!

[@olympia67]

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

[@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. The usual thing was a huge Holley with a adapter on a stock manifold...or the big honking cam with 8.1 compression and 2.73 gears...the single plane intake and stock exhaust system..

[@sideswiped6874]

some 26 years ago I re-ringed a low mileages 92 Chevy 350 car engine for a boat. it was not bored, it was professionally honed! had the stock pistons and the old 400 heads (professionally rebuild, milled down a bit). cam was a Crower boat cam, lift was around 480. with thin head gasket the compression was calculated at 8.9:1. 7 cylinder's compression was 155 . 1 was 150. sorry for the edits! my eyes are getting old!

[@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
