Ask how much it was overbored and if the crank was machined. I bought a bargain reman 250 shortblock off of ebay and then found it was bored +.080". I haven't used it and it may be okay but the books state +.060 max for a 250. At least I now know why it had a "buy it now" for $400 and free shipping. If it sounds too good........I should have listened to my mother more.
