I'm at a swap meet and a guy has a 70 340 but on the driver's side of the block it looks like it was welded like a patch has anyone seen that it's into the casting numbers too.
Did 340 ever have bad casting spits

Sounds like plain water in the block in the winter and block damage due to freezing???

Unless it's the numbers matching block for your car, or it's dirt cheap to have for a conversation piece, run away!

I have seen them frozen and busted just below the deck in the lifter galley also. Between the lifter bores and the deck. It takes an experienced welder to correctly fix a cracked cast iron block.

I didn't buy it it looked welded by the numbers and some of them were messed up so I passed thank you
I don't remember which engine I had there was quite a large, for lack of better, "casting flash" on one side of the block, water jacket. Never gave a problem. I'm sure that if you had a 600hp monster it could have been.
My dad once had a big Jimmy in an old pickup, forgot, over 300 cubes?? It had a small crack down near the pan. He had drilled the ends and plugged them, to stop the spread, but it always needed stop leak. Constantly "worked" from eitiher heat cycling or crank stress, I don't know what
