[FFR428]

Hello everyone! I am building a 428CJ engine for my cobra replica and have a few questions about crossbolting main caps. First am I better off finding original ones or does anyone know anything about the billet steel ones pro-gram eng offers. The block I am using is a NOS service block. It has extra webbing on main caps and is ribbed outside. Bought it new in the original box wrapped in plastic. Its very nice and could not pass it up! Engine will have 500 hp to start and I want the option of doing more without worry to bottom end. Finally is there anything to upgrade oiling through block. I see that southern automotive upgrades oiling on 390-428 blocks. Is this partally done by a pressure relief on back of block? What else.... thanks for all your help. G.
