What is a good engine setup for a GREDDY T-78 .85 AR TURBO? Could a Vortec 350 with a forged crank custom efi intake and plumbing work? Would it restrict a 350? It has a t4 flange. It supposedly made 750 hp or so at the rear wheels of a 400 equipped chevelle. My goal would be low elevens streetable reliable power. I am looking at my options and if this is possible it might be cheaper for me than converting to used 86/87 setup. Unless I could trade the turbo/ manifold t4 flange for an intercooled 86/87 upgrade. What would you build? Thanks for your answers in advance. The car is a decent running 84gn
