i looked at alot of 427t blocks(on ebay) and most of them ranged from 250 500 bucks for just the block, this one guy had one up for auction, the block was rusty so were the bores it hadn't been checked over by a machine shop, starting bid was 350, i waited untill the auction ends (no one bid on it) asked him if he would take 200 for it and he said i was crazy and that it was at least worth 350, told me i was a cheapskate, the block i bought was a virgin bore and had been hot tanked but not checked for cracks, i bought it under the conditions that if the block was found to have cracks i'd get my moneyback, it didn't have any cracks
