Small block water pump pulley

Just got back in town. My W/P pulley measures approx. 6 5/8 x 2 3/4.

My car originally had air conditioning. I've only owned it 10 years so anything is possible but the original engine was in it when I bought it. I kept the front end when I swapped in a 5.9.

thats a pre 70 pulley. those pulley set ups are totally different then the 70-up pulleys.
