1970 ws block

I have an original (except for the engine) 1970 - starlite black- 4 spd- RAIII Judge with factory air. It is 1 of 295. There were only 295 1970 manual transmission gto's with air. Anyway, the guy I got it from blew the engine, so I need a ws block date coded in 1970. I would really appreciate any help. And just out of curiosity, what do y'all think it is worth. It is not in show condition, but it is much better than a daily driver.

I have a WS block that might work for you. Please let me know.
