I've read a lot but I was wondering if someone could help clarify some things for me. I blew up my 22r and I want to swap a 4.3 in my 87 pickup. With a tbi 4.3 what kind of wiring is involved? What do I need to get from the s10 or blazer I get the motor from. And if I keep the 700r4 behind the 4.3 is that going to make more wiring for myself? I hate wiring because I'm not good at it. Thought about a carbed 4.3 but I'm going to be rock crawling and driving the truck pretty often. Just want the reliability of tbi. I've swapped motors before in other vehicles but always a carbed motor. Just want to know what electrical bs I can expect. Thanks guys

 

Look through the domestic swap section
