My WS4 Trans-Am 403 Engine, (that was stock and original) spun a main bearing. So I decided to rebuild. Kept and re-used original heads. The heads have been ported and polished.
Melling high output oil pump, all new Clevite 77 rod bearings and main bearings. Stock pistons but with a set of chrome rings. New fuel pump, power steering pump. Painted and some detailing.
