I have an 83 K10 with a swapped in early 70s 350. It was done by the PO. I have no idea if they are the 305 (original engine) pulleys or if they are the 350 pullyes.
I had bought replacement belts back in 2013. 15405 for the power steering to crank. 15445 for the alternator to fan to crank and 15560 for the AC to fan to crank to PS.
The AC never worked but it sure did chirp and thats where my journey begins to eliminate the long belt for the AC (short radial).
I ended up getting new belts from NAPA as they are the only ones who had the combination to make this work. I now only have a the 15445 belt, a new 15395 belt for the PS to crank and a 15455 that goes from fan to crank to ps. It does not go up to the AC even though it is still sitting there. The new belts are all nice and tight (not too tight) and no chirping or slippage.
----TL, DR----
didnt want AC but still have 3 groove pulley on crank for 350 engine
