I have a 94 S10 4x4 with a 4.3 vin W that took a dump. I have a 5.7 out of a 97 C1500 Silverado to put in with all the wires and ECM except OBD2 port. I'm trying to figure out if I'll need all the wiring or if anything already in the truck will work or any problems I may run into. I've researched tons but haven't seen this year with this engine. Since the Silverado is a 2wd and my S10 is a 4wd will I need to change ECMs or anything? I've considered to do a carb swap because I don't have a lot to spend and I have the parts just sitting around to do it and it would make the swap simple but I prefer to keep it TBI especially having the wiring already. I want to be able to drop it in and run the truck without issues, maybe not daily but still commute in it some back and forth to work. I am a little worried about grounds and sensors for the 5.7 as may of those wires were cut when it was taken out of the silverado and possible corrosion. What changes would I need to keep it TBI and make sure it'll run fine?
