Hi guys I'm new to this forum and help would be greatly appreciated, I currently have a 2001 S&S 113 evo witch is basically all factory S&S besides a Mikuni hsr45 carb and manifold. I currently have the engine torn down and am on the hunt for a set of high compression Pistons I have target ratio of 11.0:1+ . I plan on running an ev84 .640 lift camshaft with some head work as well. Could anyone point me in the right direction as to who to call or talk to ? I do realize this is a high rpm, large lift cam high rpm power is what I'm shooting for. Thanks guys!
