Mark and his guys know how to go fast. I also heard Mark Yacavone's name come up in relation to converter selection and combination. He is a SBC Stock Eliminator heavy hitter that I definitely remember.

It’s cool to see Mark got him another test car for his masterpieces.

Mild cam! That thing chops like a chainsaw!

Well there he is! Your name hasn’t come across My radar since you left Colorado. I hope the move to Texas has been treating you well. Mark, you certainly do the most with the least of any builder I’ve seen. Camaro is a great simple build, what is the race weight on that machine?

A friend in high school got an 83 identical to that one new. Even with the 305 it drove awesome. Thanks for sharing these rides

Dying to know the paint code on this

Gotdam! That Camaro is a beauty! 10:80s without the typical "Im going to buy a supercharged car". Love it man!

Very cool..!Thanks for sharing…

Bigger size fuel line will help that Camaro

Watch you video on Marks 85 Camaro same engine and parts, th350 both weigh 3150. How does Marks car go half a second quicker?

Would have liked to hear it idle.... Sweet Camaro

It's amazing what Mark can do with stock stuff. Well sorted car.

That’s a nice piece and it looks like a lot of fun!

4.56 gearing gets it off the line quickly at 120mph it's got to be turning 7500+rpm my LS2 powered Monte Carlo SS had a 700r4 transmission with 4.10 gears it did 124mph in 3rd gear at 7200rpm

10.80!!!!! 430hp sounds like you utilize every hp. Best build yet I’ve seen.

Vortec 350's were 880 blocks. WTF Is A 638 Block other than a tbi block?

That's really impressive! I don't understand how it goes that fast. I'm sure he has done all sorts of porting magic, but 10.8 on a stock 350 shortblock through a dual plane intake with that mild cam. Crazy! Love the car too.

Nice to see mark on your channel a very good friend of mine I have to of his motor ,

Is Mark going to do anymore YT content? I really enjoyed his videos.

Fantastic. Very well done. :)

Been following Mark's discussion of this car over on the Chevelle forum.

Beautiful car. I have a 82 Camaro street/strip, i built a 377 for it. (Runs on aviation fuel) Th350, stock 20 bolt with a spool and 4:10 gear, s&w full subframe kit and 20 point cage, QA1 strut assembly front. I have a 15 by 10 rim with 5.50 back spacing and a 295 BFG TA tire on the rear and fits the stock wheel well. Love your content 🤘 stay safe be safe

10.80s with about a 3500 car w/driver with only 430hp?That Is some very experienced tuning.Well done!

Had that in the late 80, started as a Berlinetta v6 theft recovery, blew the clutch then popped a SBC 400, th400 and z28 coils then blew the rear end. Drove it home in reverse (stopping at lights :) ) and threw a 10 bolt main from my old 71 Lemans SS. Miss those days. :D

Nice I need to get with you on my g body in dfw area. I need a good 400 sbc if you have any

Beautiful car! Those truck tires in the front gotta be weighing it down a little. I see the electric drive for the water pump, but no alternator?

Impressive.

Nice car! Glad to see Mark is doing well, like to see more of the white chevelle.👍🏻

Interesting valve covers. Who makes/sells those?

That's a respectable ET and good power for not a lot of money. What rear axle is that, 8.5" 10 bolt?

Nice!

SBC 400 - high rpm HP BBC 396 - almost flat torque curve

In order for you to have eight to one compression on that damn 400 small block you’ve got to have a set of 400 heads on that thing with a combustion chamber in the 80s. It doesn’t matter you could take a 350 head a regular ragged 882 and it would put it at a nine to one if you put a 300 horse head on there you’re looking at almost 11 to one. That’s a 64 cc head That’s even with the Soup Bowl if you’ve got flat tops with a 64 cc head you’re looking at almost 13 to 1 compression. I’ve got a 434 small block with domes in it and 72 cc heads and it’s almost 14 to one compression ratio

How would that cam work with power brakes? And street/strip driving

Seeing the 55 in the background, i always wonder what clutch held up to win drag week.

What is the compression ratio on this engine? Would 3:50 it require 91 octane? Thank you

Would you consider taking a wife on trade? She's got a lot of miles on her. Dents and dings here and there. Loud exhaust and I think the belt is starting to slip. Top speed isn't what it used to be but she'll get you from point A to point B. I'll cover delivery costs both directions.

I had almost an identical build, just with a roller cam that was a few degrees bigger. It was in a light 3/4 ton '93 gmc with a 5 speed. That thing would move for how heavy it was. It would chirp the tires shifting into 3rd at about 60 mph. It would also pull a loaded car trailer without any trouble.

108mph works out to be about a 12.2 et. Not bad little sbc

Why were the heads installed backwards?

Where you located

Thanks Nick

Great info! I'm looking to swap in a stock 454 from a 1985 chevy 3/4 ton truck into my little short bed square -so what youre saying is, it'll have 330 hp stock and 400 plus foot pounds of torque? I thought they made WAY less power than that.

How would that cam do with power brakes would it make enough vacuum

Hey what pistons were you running?

If y’all really want to know, the 396 is no good, don’t waste your time with them. If you need to get rid of yours I know a guy 😂

Hi nick i have some questions, sorry for being a novice to big blocks but when you say you put those 911-16 springs in, that's all you did? no replacement retainers or locks?, i know little big about small blocks but i've just got a Mark IV 454 that was running out a RV, some good 781 heads and planning to get some retrofit lifters and that cam/a very close copy by mellings (MEL-22236) and find out what push rods or just ask you cause what length since it seems i'm making a clone of this. Cam and head swap and intake and stuffing it in a 79 z28 Thanks for your time and reading.

Its not a fair comparison... square port against oval port ! It should be square port against square port . But after seeing the result i would go with the 781 without all the sign writing

Is there a reason you used closed chamber heads for this build? I have the parts around to build this combo, but the heads i have are open chamber heads casting #820

Are you in the Dallas area?
