Stock 90 Lo3 with TPI
Would there be a differance? GF is looking at 90 RS LO3, low miles and we have a 350 TPI sitting in the garage. Should we swap out the 60K LO3 and put in the 350 TPI or sell the 350 and put the TPI on the LO3?

Keep the 350. For all that is holy use it. You can use either TBI or TPI on top of it. Since the car is TBI now it may just be easier to stay with it for the time being. If you do keep TBI, read up on what it takes to go from a 305 to 350 TBI set-up.
