I just contacted Mark Remmel. I think due to my badly knocking 350, I am going to have to do two rebuilds. If I can get my 350 block back, I am going to get direct replacement Mahle 10cc dish pistons with the 1mm ring pack and either Scat or Molnar aftermarket rods. I have regular length ARP studs for the mains. I have two 330 cranks, one is stock stroke. It doesn't probably need undersize on the rod and mains, currently .020" mains and .010" mains.. It was balanced for stock rods and the now discontinued Speedpro 18cc dish forged pistons in .030" oversize. It means they would probably have to remove weight, not add it and would consider and external balance if it saves money. Something needs to be done soon.
