I have two Crane Cams and a few valve train parts. They are Crane part # 284 H12. They are hydraulic flat tappet cams in great shape. Came out of gen 4 454's. They were 525HP SC engines. Just rebuilding engines and upgrading everything. Also have lifters(mixed up),timing chains and push rods. 1 pushrod is MIA, but everything else is there. 150.00 for both sets shipped to your door.
