Hi Steve, the L2398F is also a forged piston, not cast?

Thanks, Gary in N.Y.

P.S. More specifically it is listed as being for a '68/'69 400" RA-IV unit! Basically it is still the same piston.

Not a real good move using "restricted-oiling" pushrods on almost any builds.

This is just my own opinion here!!
