If you can find a 59-60 389 block those are known for being very thick and beefy.
If you can get around the starter issue.

Wilcap transmission adapter from Speed Gems. Not cheap, but does give the ability to use Chevy bolt pattern transmissions along with mounting the starter on the ‘59-‘60 389 blocks. Butler lists an adapter as well but I haven’t researched it.

Local Pontiac dealer gave me a 75 350 block out of brand new A body. Service issue leaking coolant. There was a small crack below one of the freeze plugs. Bad casting maybe , I kept it then I junked it. I thought about trying to repair it.Its the only Pontiac V8 I experienced this with.
