That is pretty sweet.

This thread should have been posted in C3 general though.

I'd paint or powder-coat those valve covers Chevy orange to give it the classic look, if it were mine that is.

As to how much horsepower, no idea but a hell of a lot more than mine!

Enjoy those Hossiers while they last.

Nice job, I'd like to see how you'll fit that under a SB hood with that intake and carb.

I kinda like the flat black valve covers with the black engine bay.

And the engine guru's may need a bit more engine facts/info to come up with hp/tq numbers such as cam specs.

I used to have an auto tranny with 3500 stall even rolling at 35 mph in second gear I could floor it an have to let off after leaving twin 315/35/17 black marks for 200-300 feet.

Your 3800 stall and 496 if well tuned should even do better.

I agree, love the valve covers. Not sure about the stock hood attempt though. Interior looks great. Nothing personal, I'm not a fan of those cragars.

Also, have fun getting those headers in now.

Has anyone over tried to install current model496 from GM? The 8.1lt distributerless 496. This was found in some of the 1ton trucks. I installed one in our Supra barefoot boat. 425hp @5,200 rpm all day long. I know it would never fit under the stock hood as the intake if fairly large. the motor mount location are the same GM small and big block locations. The efi was easy to locate in the boat. allan

I don't know about the year of his car, but I could have installed the Hooker sidemounts on my '69 from across the street with a stick. They almost fell in. (If things can fall up!) Went in from the bottom with zero problems. didn't even ding the Jet-Hot coating.

I'm not sure about the hood.

Also 10.5/1 on pump gas? I've always been nervous about pump gas over 10/1.
