GM Aluminum Block Small Block Chevy Casting 0 359198

Can't help much but a few random things. I'd be curious to know the bore size. The intake valve looks small. The heads look "tall", like an 18 degree head. Dipstick on driver side like an early block. No gussets or reinforcement like most aftermarket blocks. No winters foundry marking, they seemed to have done most of the early Chevy aluminum parts. I'm sure it has an interesting history, thanks for posting and good luck.
