Impressive - would like to learn more on engine build to support this.
It is impressive!
I too would like to know. My guess a lot of money and secret squirrel stuff going on!
I like the exhaust manifolds too! Maybe they are extrude honed for better flow? (secret stuff) lol

And the chances of you finding out are ZERO!!!!!! You are absolutely right. A LOT of secret stuff, and the ones going fast don't want the ones not to find out how. I forget if this is the class, but basically its externally appearing stock, and internal mods even as far as displacement are allowable and pushed to the just past the letter of the rules.

Probably a 540 or something like that under the hood there. But that’s the way to do it.

There is another member here from Puyallup, WA with a couple of 1967 Corvettes. One had a heavily modified chassis with a 1375+ HP 632 and the other was a FAST 500+ cubic inch BBC, tri-power and very trick factory looking exhaust manifolds. He shared a lot of the carburetor and exhaust manifold work to make it run. Some here may remember him - Steve Barker aka TC member 632C2.

There’s a guy at our local track here with a COPO Camaro that runs this class. Runs 6.7-6.8 on the 1/8mi pulling gears. You’d never know it looking at the car.

lots of hard work and setup. Great work on this chevelle a end!

I would say the engine sticker is about 100 cubic inches off or maybe that is the total displacement for 6/7 of the 8 total cylinders. I don't think there is a 3.08 rear in there either. A lot of interesting stuff there to get to that time and looking stockish.

There was a guy at our local track that had a 72 Corvette running high 9's that looked pretty stockish. In the pits he had the hood open and it looked stock right down to the valve covers. One thing I noticed was the big old Dominator hiding on top of a C-454 dual plane intake with the eddy name and number ground off. He just said, Shhhhhhhh, lol.
