FAQ
Do I need to balance the rotating assembly?
No. The kit matches factory weights, so it drops in on the OEM crank without balancing.
How much power will it hold?
FRP rates this kit for 1,200+ flywheel horsepower with supporting modifications.
Which bore size should I choose?
Choose stock bore for a fresh, in-spec block with no machining. Choose .010" over if the block will be bored/honed or you are running a larger cam.
