I have a real nice 340 block that I am going to be building and it has TRW L2316F pistons. But the problem is I lost one of the pistons and now only have 7. The TRW pistons are now Speed Pro ZL2316F. Are these the same pistons? The 7 pistons I have are in excellent shape, and have very low miles on them, almost new condition. Will I be ok just buying the 1 piston?
