The FRP Tuning 6.4L 392 HEMI Drop-In Rod and Piston Kit is a forged 2618 piston and Molnar rod combination built to drop straight into a Gen III 6.4L 392 HEMI on the OEM crankshaft. If you want to make north of 600 wheel horsepower on your 392, or want to run a camshaft bigger than FRP's Titan II, this is the kit. FRP rates it to support 1,200+ horsepower with supporting modifications.
