power steering pulley/ 1 or 2 "V" groove?
I have an 85 iroc with a tpi setup. I put in a 383 stroker and never put the AC back in and will in the future. I need a power steering pump and pulley and when I look closer I do believe I do not need a power steering pulley with two "v" belt grooves, which is the pulley I have now. I thought the Ac compressor ran off of the 2nd groove, but under closer look I believe it does not. I believe the AC compressor runs off of the water pump or main crank, I have to go look again to be sure. Anyone know why my power steering pulley has two grooves and if I can go with a pulley with one groove for the power steering pump. Thanks for the help. F-bomb.

The innermost groove on the PSP pulley should have a short belt that goes only to the innermost groove of the crank pulley. Although, some WP pulleys have a 3rd groove that lines up with this one, and the PS belt goes over the WP as well. But I think that had been entirely discontinued by the early 80s.
The 2nd groove of the crank pulley is for the AC. This belt also rests in the outer groove of the PSP pulley.
The 3rd groove of the carnk pulley is for the WP & alt.
There is an additional groove on the WP pulley that drives the AIR pump.
Put the PSP belt on first, then the AC belt with th ePSP still loose. Then tighten up the PSP belt WITHOUT PRYING ON THE RESERVOIR. Then tighten up the AC belt. Then put on the WP/alt belt and tighten it, then put on the AIR pump belt.
