Throw a carb and supercharger on it and call it a day. Like all the guys said, TBIs don't play nice with forced induction without TONS of tuning, data logging, and a ton of headaches. I helped install a Whipple on a TBI 350 in my buddy's Hummer H1, and we didn't modify anything else. There were two chips burned for it by Brian at TBIChips. The first one didn't have the shift tables for the 4L80E, so it was always in limp mode, and the second one, with the corrected shift tables and a few tweaks it still barely runs.
Personally, I am currently consulting with Mark at gearhead for my Vortec/TBI hybrid chip. Guy seriously knows what he is doing, relatively inexpensive, and is a super nice guy to boot.
