Ditching the TBI for carb...

[MidwestMan]

I have an 87 Silverado 4x4 with the 350 tbi and lock up 700r4. Trans was rebuilt and beefed up a couple years back, but the motor is getting in need of a freshen up. With that said if I tear this thing out this summer I'd like to dump the TBI and build something up a little that would give more smiles per miles per say. Dug around the last 45 minutes on the web with not much solid advice besides don't do it.

Soooo what does a guy need to know? Another question is the 700r4 in the 87 computer controlled? Would I be better to swap say a 350/400 turbo in, if so how extensive is that?

Thanks in advance!
