Inliners International Forums General Discussion Hi Performance Geometry isn't fun

Thanks for those numbers, panic. That also jives with what I got from Harland Sharp. The specs they gave me are 1.59 for an inline six rocker and 1.649 for a BBC. I think I'm going to order one of each and see which is closer to the center of the valve stem when set to be 90* at mid-lift. It turns out my cam has .606 lift with a 1.8 or .589 with a 1.75, so now I know what to shoot for pattern-wise. I'm kind of hoping that the long length of our pushrods makes the geometry on that side less critical. This probably isn't all that important for an engine that will only make 425ish on motor with boost. I just figure the more attention I pay to all the little things, the less nitrous I have to run later, or the less weight I have to pull out of the car. And, learning is its own reward.
