SBC Solid Flat Tappet Camshaft New in the box. We designed it for a 406ci SBC. Howards Camshaft ground it for us. We put a different shelf cam in the engine while we were waiting for this one to show up and just never took it back apart to swap it. This cam we have had laying here for about 5 years but going to swap to a roller instead so we dont need it anymore. Cam card is in the pictures
