There are a LOT of turbo Buick V-6's making enough horsepower to put those 3,600-pound sleds into the tens... and some in the 8's an 9's using that (200-4-R) transmission... I don't think it's weak....
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.
