Hey guys i have a few questions about doing this swap. i am going to put a carb 383 in my tpi iroc. i want the engine bay to look clean, so im thinking of taking out the engine wiring harness and buying a new harness for a 3rd gen with a carb if they make one. Where can i find a new harness for my application?? Also what else am i gonna have to change besides the sending unit in the tank, and gas gauge? And if anyone has any other things that they would like to add i would greatly appreciate it!!!

 

I guess the answer here depends on how far you want to go with the "clean" look...

All a small block really needs to run are hot leads for the starter and distributor, and an alternator wire is a good idea if this is a street car, so you could just cut everything but those off.. of course your gauges would stop working then...as would your A/c and cruise control...
