Bullet Race Series is CP-Carrillo's 2618 forged aluminum piston for LS builds that see boost or nitrous, and this set is machined to a 4.130 in bore, 0.005 in over the LS7's standard 4.125, for a 4.000 in stroke on a 6.125 in rod. The crowns are 4.6cc flat tops at 1.120 in compression height, which works out near 11.2:1 against 70cc chambers, and they run a 0.927 in pin with a 1.2mm, 1.2mm and 3.0mm ring pack. Wrist pins and rings are included. These are cut for 12 degree and 13 degree cylinder heads rather than stock LS7 castings, and they are sold as a set of eight.
