I want to build my own engine someday. I just rebuilt my first automatic transmission last month and she shifts like new. It has boosted my confidence enough to attempt it.
I 'liked' your comment because I was in the same situation rebuilding a Ford 351W. After blowing so much cash on Ford's I went Chevy and never looked back however Ford has simple electrical troubleshooting processes which I'll give credit to but a Fluke device makes it easier on a Chevy. Good luck on your future engine build. 🔧
I have a 427 in my 1966 Chevelle which was built in 1983 by a big block Chevy expert and it still runs great. It’s fast. I’ve had it rev to 8000 rpm. It was built with Isky triple valve springs and high quality parts.
I'm a Big fan of the 427 in early Chevelle iron I had a 68 Chevelle years ago with a 450 HP 427 and a super T10 The heads I got from a buddy were the snow flake GM Chevy Aluminum Rec port they were 113 CC heads I used to old Tarantula intake and an 850 cfm Holley . I used Hooker Super comps with a single tube out the frame rail a 12 bolt 4;56 rear and a set of cut Moroso trick springs up front with 90/10s I used the Zoom clutch & Pressure plate kit . I trimmed as much as possible from the rear wheel opening to use the 11 inch M&H I had . they did rub once in a blue but not bad ...I miss that car more than the 70 CUDA 440 6pack I used to own Or the many GTOs ..a guy I knew had the same car but with a 396 who did a hit and run when I got back to the shop monday morning the entire Nose clip was stolen from my own Chevelle . it took a couple of days but I got word some kid name Ray was rattle can painting a New front clip for his 68 Chevelle.. I'm pretty sure I was Born a motorhead .I got my first 66 Chevelle 300 Deluxe when I was 15 .. My last Chevelle was a sweet heart White with black interior 72 SS 402 only it had the TH400 .
My 427 home built had 11.0-1 compression, Eddy rpm performer oval port heads. Cam was a custom ground hydraulic roller, .585/.585 with .245/.255 @.050 on a 112 LSA Holley Strip dominator intake, 850 dbl. We made 550 HP and 513 tq N/A I also ran the bottle on it, and got my 3500 lb camaro to run 9.92 @ 130 mph. with an Eddy 250 bottle Hit.

Small intake, cam, heads that dont flow much. About right....what you guys, some dont get is the tq nd how early it comes on. Peak hp means zip on a st car ad 500hp takes more than most think. Put a solid roller and afr 265 single plane now youre making a bunch more
I can't imagine trying to shoehorn that big block into an s10.......my 2wd 1996 jimmy is going to get a 350. I wanted to go LS but that looks like an expensive nightmare to cram into a S chassis.
What I wonder about is: Where are all these parts made and how well they are made.? One bad rod or piston can hurt everything. I really like the dial-in to correct clearances. I would love to build a coyote small block. Only if I could spend the Money- REAL MONEY all at once and build the engine from there. I would build a small block stroker or hi pro, small block instead of a heavy big block.
After all those mods, this old big block makes about 505 horses, which the LS7 does right out of the box. In fact, I would be willing to bet that the LS7 makes closer ton 550 hp right out of the crate. Looks like the great LS heads and 4.125v4.0 B/S has the advantage. I still do not understand why this big block makes that much less power. You would think that it's bigger bore and shorter stroke would be a great recipe for both power and torque. I bet aftermarket heads holds much more power and torque.
True that!! A stock LS7 would push around 550-580 on a engine dyno with a flat tappet cam and “outdated” stock iron heads. The engine in the video should’ve push 600+hp with that setup.
If you haven’t already done it could you do a video on the 3800 3.8. Starting with a used one and slowly upgrading it then adding a supercharger. I have one with 28k miles on it and want to put it in a rail buggy. I also want to find out how much power I can safely make.
@@backroadsliving7740 it came from the factory with a super charger in several cars like the Monte Carlo SS and Pontiac Grand Prix along with several others.
ID say 400 is safe its kinda a rule of thumb thing. Most engines can push twice the horsepower than it came from factory with, mostly due to fuel injection and computer tuning. Even a little civic engine a d16y7 that comes with 105 HP can put down 225 wheel hp reliably. Most engines seem to last at double horsepower on stock parts. If you are going with supercharger turbo or nitrous take pistons out and gap rings and put them back into same cylinder.
What ever happened to Mike? I didn't care much for him when he started because he seemed very arrogant and still did in later shows, but he was good at what he did. He did calm a lot after Pat started, a true and real builder.
You can measure the clearance of other bearings and swap larger smaller to make the difference or even use a half shell that is one size larger smaller to get right!!!
@@bmstylee exactly. I'm not gonna spend an extra 1000+ just to remote start a car with EFI. Well maybe if it was unique like an EFI BBO or Pontiac something different
A big block with twins and the same money will make more than an lsx cubic inches will always win. That's why TAF nitro cars and radial cars are big blocks not LSXs
Why use 93 octane? Here in Au it's the lowest grade poverty fuel. We use it in lawnmowers. Do you guys not have 98 octane at the pumps? Or 95 at a very minimum?
It’s a different rating system. Here in Aus we use the RON rating which works out to a higher number, America uses either MON or AKI I can’t remember which it is. Pretty much their 87 is our 91. Our 98 is pretty much their 93 if u get what I mean
I see the problem with your 427 bill it's the cylinder heads the cylinder heads cannot flow enough air to create more than 800 that 427 need more air flow the head should have a dollar port with no bolt hole in between them and you'll get somewhere to go fast
At cfm x2 @.600 lift it's enough to make 616hp on the motor They need to spin that thing to 7k-7200 and they'll see 800... And tha 1000hp is really 850. I heard QF carbs are really what they say
Real engine builders and machinists don’t say “twenty eight ten thousandths.” Although technically correct, the lingo is “Two and three tenths” thousandths.
So a couple things to note. With a bigger cam and ported heads they only picked up 30-40 HP. No big block on the planet would peak at 32 degrees unless prostock or something similar. Wish they would have found the magic with timing first..

Thanks for your knowledge, much respect to you all.
Ha. First time I see Pat using one of his pens😉👍🏼
BTW, nice build.
Really enjoyed, great vid.............................. 👍👍👍👍👍👍
After watching this video , i now know i dont have enough money for all the tools these 2 guys have to build a motor. 😂😂
A two piece main seal would also allow to to lay the crank into the block😉
Vacuum pump looks like it's going to get in the way of the steering on the S-10. Think happy thoughts.

I want to go to the swap meet Where these guys shop, they get the best deals! Lol
Leaded gas back in the day was really good for hi compression, I dont know about todays gas.
very good work

Kool an thanks!
Looks like a perfect repower for a JK.
800hp would definitely wake it up.
Man that things a Dud
How much for the 427 with the 1000 cam carb crate style ready?
10,000
22k in australia 480hp
That 427 crate engine
Why do you use so many assembly lubes? Sponsers?
Powernation can you’s do something with a Australian holden 308 or 253
I do the same thing with toluene. Which is probably what that is. Wouldn’t surprise me.
How about some update shows
I know this is an older episode, but did you notice any orange staining/buildup on the spark plugs from the "Race gas" additive?
Give it time. That junk will stain your plugs and the combustion chambers.
After all the initial work and using the same carb before the upgrade, there was only a gain of 28hp!
That cam was still pretty small and the head work was really minimal.
orig carb was holding it back a lot says things
Man I wish I had a little small block built by pat for my 1985 chevy k10 .
Do the low tension rings affect oil consumption?
Yes it is not worth the 5hp gain, it can be made upgrading something like the intake manifold and a more aggressive cylinder head port
Man, you can tell it's an old episode because Pat has hair
And Mike is in it
@@aleklukacs6170 has it ever been said what happened to or where Mike Galley went?
Lol yeah
@@AlexRamstack oh cool why did he leave?
@@alanhill5513 He married one of the Kardashians, and moved out west.
Anyone know the brand of torque wrench that was used?
How do you correct a bearing that is just a bit out of tolerance either way
You can measure the clearance of other bearings and swap larger smaller to make the difference or even use a half shell that is one size larger smaller to get right!!!
There was no discussion of whether or not the crank is cross drilled to ensure 360 degree rod bearing oiling.
Yo quiero ver motores 427 carburado sensillo de este modelo de tapas varvulas pero con bomba de gasolina mecánica laq va pegada en el block🤩👍
Who makes that assembly tray?
How thick are the bearings in comparison to each clearance?
Depends on if the journals have been machined. They make oversized bearings for the common journal overbore sizes.
can you guy build a ford 3.5 equal boost twin turbo
Did he say that 427 was going into a bumpkin pick up? 🥜
Not a fan of nitrous but other than that this is a very nice engine.
Yeah should build and upgrade a 4.7 magnum
I need send you guys my 454 to build for me
Nice engine.
Way carburator when you can go injaction ?
Simplicity. And when this was originally aired FI was not as affordable as it is now.
@@bmstylee exactly. I'm not gonna spend an extra 1000+ just to remote start a car with EFI. Well maybe if it was unique like an EFI BBO or Pontiac something different
Would love to see the 4.3 lv3 v6 e85 GM engine build, fairly new engine with lots of new potential! Think about it
Corvette is the only way to go Weight ratio I mean ?
g body is good
You guys do great work. I wish you would take over my mustang project for me. Thanks for the videos
Lol I wish I had the money so I could do it myself
@@coconut_milk7167 its time money and knowledge. I cut my mustang in half due to rust. Was a nice car
LSX 427 with a set of twins will do double that. Big blocks are old school tech at this point. It does have a certain nostalgia though.
You forget this is a stealth engine turbos would give it away
@DFB58 not so much the look but the noise the wine of a turbo is very distinct also people will notice your intake goes off to somewhere else
You could add twins to this and it would be way higher also
A big block with twins and the same money will make more than an lsx
cubic inches will always win.
That's why TAF nitro cars and radial cars are big blocks not LSXs
Put a set of AFR heads on that motor and it easily picks up 100+hp. It’ll make every bit the same or more than an LSX427
Yikes! All that work and no rob bolt stretch gage?
I hate welded pump pickups they make bolt on 1s for deep sump pans amd better pumps
Is Mike still apart of Powerblock Engine Power?
No he disappeared some years ago.
Cara vocês entendem muito de motores V8
Wish you blokes were in australia I'm trying to build a 308 Holden stroker 355 .don't trust anyone so it's ongoing and annoying
What happened to the cameras?
Why use 93 octane? Here in Au it's the lowest grade poverty fuel. We use it in lawnmowers.

@@danmyers9372 i think around 8 yrs ago they had morel high RPM short travel lifters they were just 800-1000 dollars back then

509hp with a roller cammed 620 lift, roval alum heads and 10.7cr !?? Something is wrong with that engine. Should’ve made 600+ on an engine dyno easy.
exactly. My 427 with profiler 320 heads makes 635hp. 10.8 to 1 comp and a solid flat tappet cam.
Small cam, old hydraulic roller lifters, mediocre head flow and the wrong intake manifold.
That triple spring is so outdated. A modern beehive double spring will free up HP and make the valve train way more stable.
This was probably 8-10 years ago. Correct though
Very clearly a dual spring. And as S Model Mafia stated, this episode is from 8 years ago
427 son 6.997 litros
509HP out of a 427 with a vacuum pump, aluminum head, roller cam, low tension rings?
Yikes
If it was to the wheels 400🤣
Should’ve pushed 600+hp, something is wrong with that engine.
Wrong part number for cam your part number is for retro for.
HV pump is not good and not needed want drain the oil pan at High RPM.
What ever happened to ole Mike Galley anyway..? ?
This is a good episode but it's been shown to many times.
