The cheapest swap you could do other than the original motor, is the 4.3 NA V8... By far. You might be able to get by for $1500, motor and parts, but you would have some serious shopping to do, it would probably be a higher mileage motor and they're only a little more power than the V6 you have now.

Do some research on V8's. You could also read the beginning of my thread. The link is in my signature.
