I posted back a few months about a 427 I bought at an "estate sale". The block was sleeved poorly and a couple of other issues. I have been searching and found several but the prices approached a new block from BBM. So now I have located a nice C4 block real clean ..nice water jackets, no damage from blowups, But sleeved all 8 holes looks done correctly with a step and does not look like they hit water anywhere. I also found another C4 block with std bore but no inspection for cracks. Lastly I found a marine block center oiler honed to .030 now and should clean up nice at .037. A clean block in the water jackets and supposedly passed inspection.
I offered $1500 for the sleeved block but got no reply. I also offered $1500 for the marine block. The C4 block is a shot in the dark with no inspection for cracks but should clean up nice at 4.25 or a little more, this one started at $2500, so I walked.
Am I off on my prices? I fiqure a nice block that has been inspected maybe worth $2000 and more if a side oiler and not bored to the limits. Nobody gives a warranty on a used block if it turns out to be problem.
