Not to mention if you buy a rebuilt engine, most come with some sort of warranty. Some things to think about here..
you are correct in thinking that it could be the crank. how ever the cam should go well before the crank. i have rebuilt a couple of these that have been ran low and or out of oil and it has been the same on all. i just had to rebuild the top end. one of the motors have 15k after the top end rebuild and its still going strong. you can buy a master rebuild kit for $500 plus what it would cost to machine the heads. even if you take it to a mechanic it should cost less then a motor swap.
