I have a 91 GMC RCSB that I just put a 4/6 drop in. It has a 700R4 in it. I want to LS swap the truck. What LS to use? Its a street truck used as a truck. hauls a atv sheetrock, mulch etc. I want to swap it cheap. No custom harnesses or dashboards. I dont want to get a pcm tuned everytime I change something. I was thinking a carbed lq4 with a torque biased cam hooked to the 700R4 and 3.73's. Does anyone have any good input here?
