Default Need help identifying this SBC part

It's a rat rod for sure. It's in a 1939 Pontiac. I know its a 010 block, maybe from a early 70's Monte Carlo. It's got a LSD rear end but i'm not sure by who! Reverse threads on the axle studs if that help.





Any help would be fantastic guys!

All the best,
Aaron Lephart

Looks like an oldsmobile/pontiac rear from the 1950's (I believe they were a 9.3"). I am not sure that they came with the reverse threads though.

Thank you for the help! It does indeed have reverse threads on the stud on one side only! I actually left that tidbit out of my description on purpose to further verify it!

All the best,
