If you are wanting a good running engine that does the job with out tons of hp, I would go with an older late 70s, early 80s 231 V6. If you are looking for a little more oomph and a lot more customisability (is that even a word?) I would go with the 4.3L Vortec from the late 80s through the 90s. Both should fit without too much modification. If you look for a 231, look for the one with the distributor in the rear of the engine. You should be able to find either of them for 2-300 dollars.
