Slant 6 with 200r4?

Correct. I remember when the cars were new. Knew a guy that bought a new one in fact. All he did was chip it and put slicks on it. Instant tens. NO other mods. It had factory 4.10s already.

I did some lookin and there's no way his car was that fast with those two mods alone. But It WAS a 10 second car. I remember solid 10.70s. I will call him tomorrow as we still keep in touch and see what all he did to it. It wasn't a ton, I remember that. It was an 87 GNX. It was bad.

That will be interesting. SOME of the really serious Buick guys put a Powerglide in their cars, but the great bulk of them leave the 200 in it and they don't seem to have a lot of mechanical problems with them, even running tens...

That was my point... they seem to be able to handle 600-700 horsepower...
