Another swap question

[86cutty]

the block was bored .030 over with comp cam and a set of L88 corvette heads i believe with with oversized valves and springs. the duration on the cam is 286 and 296 i think with 507/510 lift. The engine was making 400 supposedly before the head work and the cam kit. Just making a rounded estimate four and change to the wheels is plenty for me.

If it's a 350, there is no way you have L88 heads on it! L88 heads came only on a limited production 427 Big Block powered Corvette made in 1967-1969. Less than 300 cars were produced, and most were intended for competition, not the street. They did not even come with fan shrouds when new. Remember-350=small block, 427=big block when dealing with a stock displacement Chevy V8 ( yes, I know that Hardcore Products makes 454 strokers and I believe World makes a 427 small block stroker too). Big Block heads WILL IN NO WAY bolt to a Small block!!!Only the distributor, transmission , alternator and carburetor will interchange. The only Big Block engine ever to come in a 350 ci displacement was the Chrysler B wedge, and only in 1957, 58 or 59-I don't remember which year off the top of my head.

maybe im thinking of the wrong number but it is a small block from a 69-71 corvette/chevelle with stock chevy 2.02 heads something along those lines i just cant get the numbers right.

The most likely candidates in those years would be the DZ 302, LT-1 350, and the 350 hp 350 used only in Corvettes-maybe the L-48 350( but I think it has 1.94's) Those heads are now reproduced by World Products as the S/R Torquer. I have a set on my 350 and they are OK, but not as good as more modern head castings with newer technology.

Supposedly being the key word there. i doubt it was making 400 in the first place. ppl usually. think there cars are making more hp then they really are.
