I am in the process of collecting parts as they come along. (Meaning Cheap) For a 98 GMC RCSB 2WD 5.0L Vortec. I built a homemade twin turbo setup for it that I am very happy with, but I am thinking about a front mount twin turbo 6.0L I would like to use flipped exhaust manifolds. What I am wondering about is the Corvette or F-Body accessory drive setup. Since I have No accessory drive at this time--What should I go for? I like the Corvette setup the best, because it sits 1 inch closer to the engine than the F-Body. But, I am not sure if flipped Exh. manifolds clear one drive setup better than the other. I figure this is the place for the best info.
