The Bullet Series BF6152-STD is a forged 2618 aluminum piston set for the Ford 351 Cleveland, sized at a standard 4.125 inch bore and built for 412 and 438 cubic inch combinations. The dished crown measures 0.064 inch deep and returns 11.7:1 compression against a 50cc chamber, with valve reliefs cut for CHI 3V Kaase cylinder heads. A 1.250 inch compression height suits a 3.875 inch stroke on a 6.000 inch rod. CP forges the Bullet Series on the same machines and tooling as its CP-Carrillo branded pistons, with contact reduction grooves, an accumulator groove and dual forced pin oilers. Each set includes a 1.5mm, 1.5mm and 3.0mm ring pack, 0.927 inch chromoly wrist pins and wire locks.
