Well bought a 1999 C5 with around 160 thousand miles. The Engine does not have the power of an even stock vette anymore. Raced my brothers stock 2002 Z28 and lost really really bad. Vette has ram air only mode. Will my iron 5.7 work on the vette by that i mean oil pan will it fit on the 5.3 block? Also any thing anyone might know please help. Rear end on the vette spent most my extra money on it so trying to use the engine from the truck. Ls1 will be going in the truck. Truck rarely gets used just trying to make this vette my dd and want it fast.
