    Can anyone offer a suggestion on fixing a cracked block at the passenger side starter mount? It is causing my starter to loosen and eat my flywheel and starter gear. Any suggestions besides the obvious of replacing the block would be appreicated. Can you weld the crack? Would JB Weld work?


    Thanks in advance.

    I have heard of people getting the block welded up. That might be an easy option.

    That exact thing happened to me a couple months ago, even had a post about my problem. Yes you can get it welded up. I had mine welded up, and I also made myself a starter hold bracket for the tail end of the starter motor that bolts to the block.

    Had the same problem, got it welded up, with a lifetime guarantee. Cost me $200. Small price to pay when you think about the cost of a new block.

    WEld it and GM sells a starter brace for a SBC, it's like 7 dollars. The brace will keep the starter from torqing out, they are used primarily on high torque motors like deisels. I have a brand new one here if anyone wants it.

    most all SBC came with a rear mount brace since back in at least the late 60's ive got several ive saved off of old 307's and 350's and such form 67-72 years, but i just tossed em all out along with all kinds of old style engine mount trees and mounts and clutch linkages last week.

    good luck
