Since I've been lately playing around with my engine accessories, I figured I could do a little write up on serpentine pulleys used on 302 and 351 engines. Some of us don't want to spend the $$$ on billet stuff.
Thank goodness Ford standardized their serpentine pulleys for the most part. Pretty much everyone knows that the factory V belt setups are a complete mess if your going to mix and match.
I'm going to concentrate mostly on the 1979-93 Mustang and 1987-96 F-Series/E-Series because they have automatic tensioners and you can mix and match them. There are some Cougars and Mark VII that also share the Mustang setup. The Crown Vic, Grand Marquis and Continental is sort of an odd ball setup with dual belts and manual adjustment.
I'll start with pulleys first. This isn't a complete list of all the pulleys offered. Ford liked to update part numbers even though the pulley is the same. These are most likely what your going to come across.

The 2G and 3G alternator pulleys aren't interchangeable. There are a whole bunch of various sizes of pulleys out there to choose from.

These require a reverse rotation water pump. The bolt pattern is different from a standard rotation pump. The 1979-93 Mustangs used a standard rotation timing cover while the 87-96 trucks/van got a proper reverse rotation timing cover. Typically replacement Mustang water pumps just have a round whole on the back plate so they can bolt to either style timing cover. Truck/Van pumps do not. Crown Vic/Grand Marquis/Continental have a ribbed pulley for standard rotation water pumps.

This is where you have to watch out for. Ford started using a 4 bolt harmonic dampner in 1970 and have made them in different thicknesses over the years. You may require a spacer on your harmonic dampner depending on what year it is.

This is pretty simple. Ford pumps require a Ford pump pulley. There are a bunch out there since the pump didn't change much between 1978-2007. Don't really know why they used a plastic pulley on the trucks and cars (except mustang). The E-Series Saginaw pumps require the Saginaw pulley as the center hole is bigger.

I'm including these pulleys for those that might be required to have them or those going to run a vacuum pump and don't want spend money on a billet pulley.

The newer style tensioners will fit the older Mustangs but will require a nut for the bolt. Cars used a 76mm pulley and the trucks used a 90mm pulley. Otherwise they are identical. The 1993+ truck tensioner is its own design.

Both styles of the Mustang brackets are essentially the same. The 1985 and up brackets just added a threaded boss for the tensioner and sliding metal sleeves on the accessory holes to account for any slack. The 1993+ changed the alternator mount to a three bolt and tensioner. It also requires an idler pulley if the air pump is removed. The older style is much better looking. All mounting brackets bolt directly to the head so they work for a 302 and 351W.

The Mustang brackets WILL NOT work on a 351W as they have separate brackets that bolt to the head and water pump. The truck and van brackets are designed to bolt to both engines. Its probably best to stick with the truck/van brackets as they are self contained. The Mustang ones have several pieces and get confusing if it has factory or dealer installed air conditioning.

Hopefully this might help someone out.
