well i'm on the sreach for a new car/truck. and well if i get a truck i was looking at a blazer or jimmy. well i don't CPI cause it sucks. yeah yeah i know it make lots of power but it breaks down a lot and eats fuel pumps and those dumb spider thingys. now for my question: how hard is it to swap CPI to TBI? i have the intake and TBI and computer just no harness. cause if i get a blazer or jimmy with CPI i'd like to do the swap.

why? i had a CPI and never had any problems with fuel lines/CPI unit and nut kit, or anything. i had numerous problems with my TBI, however. anyway, i believe the cam and heads are different, the TBI has a computer in 1995 (OBD1.5) and youd need a new harness. waste of money, in my opinion, but thats just me, and im sure there's people out there who will recommend you do it.
