66 A/C Compressor

[Jerry G.]

Can anyone tell me the correct diameter of the A/C pulley on a 66 small block, 300hp, automatic with P/S, P/B? Is it 5 or 5 3/4? Thanks

Michael -- just typed in the Delco part # 15-216 on their website, and it still shows. May not be cheap (compressor rebuilders probably have many, although it wasn't the most common diameter). The new Delco pulley assembly probably includes a new bearing as well, which is a plus.
