You could probably tune a TBI to run well on a modified setup, although I would not bother with such primitive EFI I just don't see the point. The low compression, small cam, TBI setups are pretty awful but it's not due to any one particular factor it's the combo. Basically the only thing I changed from a stock 350 TBI is.everything LOL. And flooring it from a roll lifts the nose when it grabs the next lower gear, it has some grunt to it to be able to cause any weight transfer in this 5200 lb heavy thing. It will blow the tires away from a stand still just rolling on the gas, I need to put a posi in next to be able to hook this thing up at all. Man does this truck run strong with mildly worked over 083 heads, an LT1 roller cam, and mass air TPI with some chip burning. I ditched TBI for TPI on my long bed ext cab K1500 and went to 083 heads (Vortecs would be even better.actually look at the $100/each vortecs in my 1980 Firebird thread I just bought and am putting on another 350 roller cam build). If you need help determining which specific tuning parts to buy I can help. So your best gains right now, if you plan on doing any upgrades to a TBI, is to invest in a chip burner, datalog cable, and a wideband O2 and controller for it.
