Ray I wish I had an extra $850 for one of your harnesses but at least I'm having you guys tune my ECM. I just wish your tuner was in town so he could finish mine today! I'll be back in Killeen tonight and won't be able to pick it up until the end of the weekOriginally Posted by Ray@NP
Best thing do do is dump the old gas gussling 350 and tbi system altogether and do an LS swap. U can probably do it all for under $1000 or less. If u can find a donor vehicle it will make the swap alot more easier. If ur on a budget heard the 4.8 is great for daily driving or for boosting and just has a bit less power than the 5.3 (I swapped In a 5.3 in my 94 c1500). 6.0 is ideal but very desirable and pricey. Between all 3 wire harnesses are about the same. U can mod your own harness thru lt1swap.com and he can remove vats (vehicle anti-theft system) from the ecu for like $75. Vats must be removed after you swap it in or truck will not start. I pieced my swap together and it was a pain looking for parts on the cheap. So that's why a donor vehicle is best. Any drive train under 150k miles donor vehicle is fine. U need mounts and if you do the harness yourself, u save alot and it doesn't take but a few wires to hook up the LS harness to ur truck.
