I am active over on the 67-72 forum and have a question that is out of scope of knowledge on motors. I have the opportunity to purchase a 1999 2 Door Tahoe that has 117K mileage in very clean shape with automatic transmission, no motor in the vehicle. If I was to buy a used motor to drop in what would be the way to go just for a daily driver. Current motor is 5.7 Vortec, would a newer 5.3L match up to the current computer or does that need to be changed out? Thanks!
