you can fit just about any motor in it. If you want to put a 350 in then you may need to lift the body to for bell housing clearance and a few custom brackets. Or look kit to make another engine fit. If you get a another 4.3 crate motor then that would be an easy weekend or 1 day job. A junk yard motor would run about $500

I think I understand your question now. You can get any 4.3 with the same injection system. The blocks are all the same. The main things that vary are the pulleys, brackets, etc. Which you will pull off the old block and put on the new if need be. Typically you can get any 4.3 but may have to swap the intake system over to stay compatible with your ecm. There was multiple injection systems on those suv's
