The CP-Carrillo Bullet Series LS7 piston is a forged 2618 aluminum design for Chevy LS engines with LS7 12 degree cylinder heads. This set pairs a 4.130 inch bore, 4.000 inch stroke, and 6.125 inch rod length with a 4.6cc flat-top crown, giving roughly 11.2:1 compression with 70cc chambers for strong naturally aspirated response while remaining compatible with moderate power adders. Compression height is 1.120 inches at about 484 grams per piston, and each runs a 0.927 inch wrist pin with a 1.5mm, 1.5mm, 3.0mm ring pack. The set ships complete with pistons and rings for all eight cylinders.
