Picture attached.

Not sure if they’re all the way through or not the builder didn’t say but is said if it was him he would get a new long block but I want my original if possible. 87 tbi 350 with 68k miles.

Weld with nickel rod or belzona or get a new block? Thanks

Get a new block, cheaper than having it welded and no worries. Looks like a possible freeze crack

The number of cracked blocks is going to be shocking here in Texas, between boats and cars and the first time EVER for sub zero temps.

I agree, either get a new block or get a GM crate engine. I have had great luck with them, especially if you are doing stock or near stock applications.
