If so the SRP piston is a high silicon piston and the expansion is less than a 2618 forged piston. I personally will not run a SHP pistion, although that's what a lot of builders use because they are about $150.00 cheaper and they are not a good alcohol piston (in my opinion). I've seen more of them burn down on alcohol than any other high compression piston. JE sells more SHP pistons than any other piston they sell. The other thing is that he says on the end gap on the top ring is .035 and the second ring he says .032, but then he writes gapless, i have never file fit a gapless ring, but maybe i'm missing something. I'm not critising the engine builder, just looking for the problem same as you are
