has anyone heard of aftermarket rsx cams that can be swapped into the si? I'm looking into building an all motor si that makes around 260 crank hp. We have a great motor to do this with, but I don't know if anyone has done the research on longer duration cam profiles. High compression engines collide valves with pistons if you aren't careful. I'm sure that I will have to look into new springs and retainers as well, but I'm interested in the numbers for the cams.
