With only two letters at the end of the code shows it is a 1969 & earlier block.
1970 & newer had three letter codes. Make sure there isn't one more letter there. All the UA_ three letter code engines are 1981 vintage 305's that came in half ton trucks.
A UA code small block is a 1969 truck 200 hp 2-bolt main 307 cubic inch motor.
Put a tape measure on the cylinder bore and let me know what it shows. A 307 has a 3-7/8" bore so it should be obvious that it is not a 4.00" bore like a 350 or 327. A 305 is just under 3-3/4" bore.
Either UA code engine is not worth the effort to rebuild it when damaged.

Definitely 3 7/8" Thanks for your help. Will post more pics when I pull this thing.
