Flathead cracked

[my2nd40]

I've got a crack. What do yall think? Do I try to get it fixed or no. I can't see any other visible cracks, although I haven't had it magnafluxed yet, but I can see this one plain as day.

Assuming no other cracks, that looks like a good candidate for the "metal stitching" repair process. If it goes into a main bearing web, well, not so much.

As much money & time as it takes to build a nice flathead , I won,t repair or use a block that is cracked down there . Just my opinion ,top of block cracks & cylinder cracks are much easier to repair & never have a worrie about .
Cheers

I tried metal stiching on a customers cylinder head, cracked on the top... When he came to pick it up, I gave it to him for free... Turned out to be a wise choice, the repair did not last... As you work the plug repair, the new plugs will open spaces around your earlier plugs...
Your crack is from freezing, have it welded... pressure test it. May work, BUT as some one said, another block would be my route... They can be found, arguably cheaper than the repair... Karl

I'd find a new block.

Blocks aren't that high. It's not worth it. I agree with ol Ron. Find a new block.

I would spend the time/money to have it magged. Then if nothing else is found, have it welded and call it good. Otherwise....

At Least a 239

Unless you are doing an authentic restoration, for the money involved I would not spend the money on anything less. If that '40 is yours, that increases the likelyhood of getting your investment back if you choose to, not like a dark hole such as my '47. Recently I campaigned(offered at swap meets) a crackless 59 block with one rust damaged cylinder, needing a big bore or sleeve, priced at $400 after mag, pressure and acid cleaning. Took about five times out so shows that better blocks with caps are not that dear. Crack repair on pan rails is a money loser. Only reason to patch such damage is to drive the miles out of an otherwise great engine, then trash it. Good Luck: Fred A

I just sold an entire short block for 150.00.
Believe me it was worth it to the buyer.
