Engine swap ?

[lee250]

I'm working on some trucks for a lady and she has 2 trucks. A 93 1500 with a 350 that destroyed itself and I think it is a 91, it's the next older body style, with a V6, I think it is a 4.3. The plan was to dump the 350 and put the V6 in the 93 cause the bodys good. They are both TBI so fuel isn't a problem and I'm told that the V6 will bolt to the trans in the truck so that isn't a problem. But my question is do I need to switch the computers and if I do do I need to switch the wiring harness or will the harness still work on the V6? Thanks in advance.

yes the harnesses for the v6 and v8 are different, i swaped a 4th gen ls1 into a v6 and had to have everything, engine, wiring harned , ecm ( computer ), trans, etc. sounds like some fun, if i was there id dig in with ya haha

If you have both trucks that are complete, you can just swap the wiring harnesses from one to the other (sounds easier than it is). It's do-able and probably your best bet, people do them on imports all the time.
