Jasper just called and advised that my 251 is too far out spec for rebuild. Seems the main bearings turned in the seats and its way out. Options: (1) get a better block/engine, (2) have them spatter weld and restore to spec. I'm tending to another block. Anybody have a running 251 or good rebuildable block for sale?? Thanks.

If you can't find a 251 an alternative is a chrysler indrustial 265. They were installed in Massey Harris Super "92" combines in the fifty's, and I acquired one from an ag salvage outfit in South Dakota, which I have rebuilt and is installed in my "48 Power Wagon. It is the same size block, mounts, etc. as the 251. Hope this helps and good luck. -
Update
Jasper was able to spatter weld the galled out main journals and are machining them back to spec. Slowly, I turn, step by step, inch by inch.. etc. Rebuild is scheduled for this next week 4/10/12. Decided to go with the stellite valve stems instead of sodium filled- hardness vs heat distribution. hardened valve won.Comment
