I'm running JE ultra lite flat tops in my 10.5:1 355. The pistons are relatively thin, and I was wanting to spray around a 150 shot. Can these pistons take the heat and pressure? I heard they were designed primarily for high-rpm circle track type driving. They definately help rotating weight though, I rev 7000+ rpm and it gets there quick. Anyone have experience with these pistons? Let me know what you think about using nitrous with them. Thanks guys.
