95 S10 engine swap?

[RPBurris]

so a friend of mine has a neighbor with a 95 s10 that has a blown motor. It is pretty clean in general and we are thinking of picking it up for about scrap value. The original motor is a 2.2 but those seem a little harder to find then a v6 and frankly we would rather have a larger motor. What is involved in swapping to a larger motor? It is a short bed reg cab. In good running condition what would it be worth? Sorry but no pics yet. I am usually hanging around in the 67-72 forum but thought this would be a good place for research. Thanks.
