Hello Everyone. Question = I need a set of matching pulleys and belts. I have put together a '72 Maverick Grabber. I have a '70 351w, 4speed Top Loader, 1 3/4 " Long tube headers. I removed the power steering pump, I have A/C. I have an electric fan installed. I have a water pump from an 84 ?? I think.. it matches up with my pulley alignment. Right now I have to roll the water pump and crank pulley belt on because no power steering pump. I have adjustable alt and A/C belt pulley. My accessories are... crank , water pump , alternator , A/C .. I would like to convert from the old style A/C compressor to a smaller version. Thanks Everyone. This sight helped me get this far.
Ford pulleys are exasperating and that's being nice. I'll guess you'll need a water pump pulley for a non-P/S application, that should allow operating W/pump & alt from same crank groove. The '67-'69 289/302/351 engines with P/S used a double groove water pump pulley that one belt operates P/S & other alt, I dunno if that pulley will align with a '70-up crank pulley. The '69 & earlier small blocks used a three bolt crank pulley that will not bolt to '70-up dampers. A/C should be driven from front groove on crank pulley, no change for it's operation. I have zero experience with aftermarket A/C setups. Here's the '67-'69 pulley arrangement I'm referring to. I recently installed installed P/S, on my '69 Fairlane, needed both water pump & crank pulleys. EDIT I just checked Ford Master Parts and the water pump pulley for '71 & '72 Maverick 302 without P/S is ID as C9OE-E, that's a '69 pulley so my above ramblings should apply. 351 & 302 use same pulleys.
I had a hard time getting belts for my stuff because many parts houses only go by make and model, and it was...well...cobbled. Auto Zone had a device that measured the belt and gave a part # based on size, so getting one an inch longer or shorter was no big deal. You might want to pay them a visit when you get that far.
I have converted my AC to small aftermarket setup. However, I am running PS, so can't speak to your belt issue. I don't know if your planning to go w/ OE Ford pump or aftermarket; I got my entire setup from Classic Auto Air. If your thinking aftermarket, might want to contact them -- they may be able to advise on the pulley/belt issue.
