327 SBC block ?
 

I am in the process of building a 327 race only engine. I have a '63 block which has a crack line about 1" each side of the block drain, both sides, outside only. i can fill it with hard block OR i have a '64 block which is OK.
the '63 block is no good as is, so i don't mind filling it.
what would you do?

thanks

the cracks can usually be repaired fairly inexpensively and then it can be filled if you wish, but it's not necessary.

My 265 had a similar crack on one side. Since this was such a rare block I had it stitched then patched up with Belzona epoxy.

I would use pinning process,Lock-Stitch has a good product ,pin it and seal up completely
then hard block, hard block may not stop a leak I have seen water leak past it so I would'nt rely completely on block filler sealing a leak.

You would be much better off going to a 4 bolt main block. The small journal blocks were proned to cracking cylinders. No sense starting off with something thats damaged.
