Hi Lang, I love your engine, i imagine that it will be twice hard to tune both carbs. jajajjaajja!. Very impressive combo, Did you have to modificate your muncie to support all this brute power of your 540?. thanks.

Alex.

In my country Spain when a car has a big engine we called it MORLACO,( it`s the same thing called your car a best with horns) so you have a big morlaco in yor car... jajaja!!!. i really live verts.. my first vette was a 75 vert. Congrats for your great car.
Thanks for the compliments! Morlaco it is....

1. The engine was built locally by Bradford Balance & Machine and it's based on the article Jim Moore (427 HotRod) wrote for Corvette Enthusiast a couple of years back.

2. I have not dyno'd the motor yet but it should easily be over 650 hp based on the tests that Jim wrote about.

3. I'm running a TKO 600 5 speed with a custom built 12-Bolt rear end and 3.73 gears.

Nobody......did you do any porting of the Holley tunnel ram? Any pics inside of it? We're doign a bunch of dyno testing right now on a 572 with a few single planes and a couple of tunnel rams...but I hadn't looked at Holley one.

What sort of RPM? Any dyno numbers with RPM?

Thanks,

JIM

Here's two from forum member, 632C2. I don't know how often Steve gets on this board so here's a pic of his insane 942 hp 632 bbc.





He and Jim are probably the premier bbc guys on this site (though I'm sure there's others).
