Found a real nice 95 throttle body 350 engine to swap into my 54 3100. It came with all wiring, everything unplugged and no wires cut, with computer included. Ran perfect in a low-mileage donor truck that was hit in the rear. My tech-savvy friends are urging me to keep the throttle-body system instead of carburetor swap. This is unfamiliar territory for me but I think there are swap manuals available if I can find them. I also have a non-computer TH 350 automatic I was going to rebuild for this project, but I can easily find the 4L60E transmission that often goes with this engine if necessary. Not particularly looking for high performance. I'm building this truck for my daughter so I want it to run smooth and not be tricky to start. Anyone familiar with this swap, I will appreciate your input. Thanks
