Do you think this block can be used?

it appears to have been bored once at Somerville, all pistons are marked with a C:

at first glance things don't look too bad, one cylinder had some water in it at some point....

my fear is that having taking a single bore reading on 1 of the cylinders i come up with 3.219"

the heads had 41T marked on them. i was told the engine ran when it came out of a dump truck, has been sitting outside under a roof attached to a barn for sometime now. no signs of cracks as of yet, but i haven't cleaned it up yet, just pulled heads/gaskets, nor have i looked at the bottom end.

assuming no cracks, is there any room left to bore some more if it is needed?

any other thoughts??
 
Stock 3-3/16" bore is 3.187", so your 3.219 is only .030" over. Lots more room to bore.
But I would recheck with micrometer as a caliper is not going to give an accurate reading, due to cylinder ridge.
 
Good point Lonnie and Ralph. It didn't cross my mind yet that it was a 239 engine. Lonnie, thanks for that link, I hadn't seen that one before. The pics are pretty bad, and the deck isn't that clean, but it isn't relieved.
 
If one cylinder has bad pits in it put in a sleeve.
That block doesnt seem to bad to me.
Scrape it and check for cracks if it looks good go ahead :)
 
First place I'd be looking for cracks is around the pan rail. Minor ones can be fixed, but I have a block here that is scrap because of a massive crack at the pan rail.

If it is usable, that was a good score.

Mart.
