Thanks for your time 68TT

They can be stuck on there pretty good. I had to use a long pry bar to break mine loose after 30 years on the engine. I was afraid I was going to break the head casting I had to pry so hard.

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.
