Hey whats up. I was looking into curtis sparks pistons. Im looking at there 400ex page since im going to be boring out my engine to a 416. Here is the link. http://www.sparksracing.com/frame_1.htm Im thinking about getting the wiseco but i was looking and the JE piston has a higher compression ratio then the Wiseco piston kit. What do you guys think? Should i get the Wiseco or JE? Whats more reliable? Oh and, if i get the wiseco piston kit or the JE kit through curtis sparks, whats the difference between getting it from them and getting it from another place that just sells wiseco or JE pistons?
