Might be the xompression/carburetion of the engine. On my 350 Buick it's SP, 10.25:1/4bbl.

Real muscle cars have 3 pedals! Check out AutoGear in N.Y. if you want to beef up that Muncie.

That is a REALLY cool car, might I say. I like buicks in general, especially the big cars. And with a stick? And console tach? Nice.

Thanks I’ll definitely check that out!! I don’t know much about the 3 speeds yet but it’s definitely staying in the car there was only 750 gs 400 made with the 3 speed
