FAQ

Is this kit for boost?
This is FRP's high-compression piston aimed at naturally aspirated 392 builds. For boosted builds, see the standard FRP 6.4L drop-in kit or the FRP forced-induction stroker kits.

What compression will I get?
Approximately 12-13:1 depending on head gasket and chamber.

Do I need to balance?
No. It drops in on the OEM crankshaft without balancing.
