Thanks for all of your replys from an earlier fourm. I got a lot of good info and I'm sure I will be able to use it in my future project. What I want to clearify is the two options I am entertaining as far as engine selections. My 89 is equipped with the 5.7 TBI and I want to increase torque and horse power. I have two ways to accomplish this; I could beef up the existing 5.7 via heads, electronics, etc. The other option is to replace the 5.7 with the carbureted 383 cid GM crate engine rated at 355hp @ 419lbs of torque. I know fuel injection has it's advantages but there are limitations on upgrades if one is NOT rich, (If you know what I mean) Anyway If I can effectively beef up the 5.7 TBI to the 383 hp/torque without going into the poor house, that's the way I want to go. If I go the 5.7 TBI direction, I will be pulling the engine and completely rebuilding it. The big question is? carbureted 383 or the upgraded TBI 350.Thanks you all.......Det45 P.S. You all are WAY WAY WAY WAY COOL !
