They do if it's a "mag". Mike Sommers had 1995 gen v 502 mag MPI engines. He had them redone and installed stroker kits to make them 540's. His original GM forged rotating assemblies were removed. When I asked him if he wanted to sell me them, he said too late because he threw them in the scrap bin.
