Since you already have a 350 L05, most people would be happy with the simple but respectively torquey motor already. Intake and exhaust upgrades would be the first start. To swap a LT1 would not be worth it. Better to sell your 93 and buy a 94-96 LT1. The Computers are different types/styles and the complete wire harness, etc would have to be done, If you are an experienced self-doer / inclined elec. mechanic, then do it, otherwise buy the car w/ stock done motor of your choice.
