Like nitro fox said, unless you have the 195s already, 180s would be better. Straub designs those cams for specific displacements with specific head flow numbers. This cam is designed for 350-360 CI with 180cc AFRs.Would afr 195's be to big for this cam with 10.5 compression ratio? Its going in a 69 camaro with a t350 and a 3000 stall. 3.55 gears and a 27" tall tire.
