ZR1 LS9 in '71 Vette

Could have done without the hood window mod. The engine is not even centered.

The window would'nt be so bad if the motor would be centered. I wonder which auto tranny they are running and why..........

I love that style vette though and it looks like it performs.

Isn't the ZR1 engine capable of better numbers than that? If I recall correttly, they had a package back then for the 71 Vette that they also referred to as the ZR1 package.

The automatic could be soaking up a lot of that. And it's only running around 11 psi of boost. I'm sure you could turn up the wick a lil on boost and be around 600 rwhp.

Yeah, 71 had a ZR1 and a ZR2 option I believe it was a motor and suspension package, one had a BB and one had a SB.

Yeah the auto is sucking up some power. They increased the boost by one pound. Depends on the dyno and if the had the converter locked or unlocked.
