FAQ
Are these truly “drop-in pistons?They're supplied with rings, pins, and clips, but a .040" overbore and precise measurements are required for correct clearances and ring gaps.
What's the difference between Performance (CC) and Race (FCC)?Race (FCC) pistons include fly-cut valve reliefs (.100") in addition to the coatings and chamfered tops found on Performance pistons-ideal for high-lift cams and aggressive builds.
Do the coatings change my clearances?The ceramic skirt coating cures to ~.001" film thickness and is designed not to require additional clearance beyond proper machine specs.
Which head studs should I choose?ARP 247-4202 suits most street/strip builds; step up to ARP 247-4204 625+ for very high boost and competition use.
