I am going to do a rebuild on my 04 corbra, has a hellion sigle kit on it at 784hp at 17lbs on e-85, my goal is to get it to 850ish on 20-22psi after the rebuild. Im getting a teksid block, i will reuse the crank and rods with arp bolts but im going to get new pistons .020 over. Anyone have any current preference on pistons they are using or have any experience they would like to share?
