It sounds like you should just stick with the 3100 V6. It will give you the fewest problems. That engine came in a whole bunch of models of GM cars and minivans.
If you do a bit more work a 3.4L 3400 V6 from a GM should be a fairly simple swap. You'd want to take the computer that came with the junkyars engine. otherwise it should slide right in.
Well the 3.1 and the 3.4 were the same block and are directly interchangeable and the 3.8 also was on certain years. However - your car is fuel injected and will not run with any engine other than your current one unless you go as far as changing the PCM and wiring harness possibly.
