If I were to:

swap in an LT1 cam
Vortec heads
new intake

what would I have to do to the TBI to tune it so that it works well?

 

the basic get it running goodf enough to drive aroudn would be to raise the fuel pressure and put more initial timing into it. to get everything out of it you woudl wanna find someone with a laptop and a winaldl set up so you can data log and get a custom chip done. you can get prolly 85-90%of the potential out of the mods with out a chip, which is a good start.

later

If you don't want to get a laptop, but you have an old PC, you can put the PC in your garage. The winALDL cable can be 80 feet long.
