Would like to know if anyone on the forum has had a set of Cast OEM pistons made recently? Would like to get a set made. I have heard Wiesco will and Ross. I didn't know if I have to provide a sample to duplicate or if these manufacturers already have that on file. Appreciate any tips and suggestions as to best for the money.
Also need contact information and approximate cost and wait time. Tom

Most of us interested in the stepped piston have been dealing with Wiseco. They have made several sets... Brian Nutter is the contact on this engine at Wiseco.

Try -DIAMOND RACING-.

They can make an exact copy or any desired modification. 430 piston dome shapes changed over the years so be sure you match the piston dome to the head.
