Ya, bartamos, I ordered that part today. Nobody in town could order it, even Napa said no not available. The one old guy in town is gone on a fishing trip so his daughter was running his parts store, same answer from her. If it isn't in there system the part don't exist. For those still wanting to know. The block numbers are 3738307, J297. The Head numbers are 370357, 913, 241, 570. I already posted the starter numbers, which in all honesty, are the only ones that should matter, as I need a part for the starter. Oh, and all of this is in a 2 ton 1954 Chevrolet/GMC ( has both emblems) .
