Opinions on this 392 Hemi for sale?

Bellhousing is not the integral kind on that engine, I've got a few '51-54 331 blocks and the bell looks different. So, at the very least its a '55 331. Could also be a 354 or a 392, you'd have to look at the serial #'s to know for sure. But if it's really a '58, then its most likely a 392.

If its actually a rebuilt 392 that you can use as is that's a steal. As already mentioned, complete 392's that aren't frozen but still need a rebuild often go for $2,500 or more. Even just a worn out stock, still running 392 would probably bring $3,400. Truly rebuilt 392's usually don't start lower than $6k, even for a mild, mainly stock rebuild.

Some serial #'s. If it's a '58 392, the serial number should start 58C-, 58N-, or 58N3-. The casting # should be 1673729 for a 392.

1958 heavy trucks came with a 354, and their serial #'s would start L8C7, L8D7, L8D8, L8D9, L8T7, L8T8, L8T9, or VT-576. 1958 Industrial 354s would start IND-56A. 354's had block casting #1619829

If the casting # isn't 1673729 or 1619829, its probably a 331. I'd say the same about the serial numbers being different from above, but there are some discrepancies regarding serial #'s for the early hemi's. I've seen serial's that didn't start with any of the above. :dontknow:
