great set for the price

Summit RacingSummit Racing Verified Purchase

I have these on my 89 mustang LX 5.0 and found to be a great addition to my power adders.the only issue I had was I had to remove the powder coating from the alternator pulley to get it to fit the shaft.

Warning: Won't work for 91-93 Thunderbird 5.0/302

Summit RacingSummit Racing Verified Purchase

All: I purchased this pulley kit because it seemed like a good deal for my 93 Thunderbird 5.0. After all, it should fit right? WRONG. This kit is for 79-93 Mustangs, Capris, and Ford Trucks with a 5.0 ONLY. I wish they had made this more clear in the listing. On a 5.0 tbird's water pump, the hole in the center that the fan attaches to, the diameter of the four mounting bolts, and the diameter of the face that attaches to the pulley are all different sizes. I could fix the first two items but the last one requires that I swap out my water pump with one from a Mustang. The crank pulley is completely unusable b/c while the holes look to be in the right spot, the new crank pulley about 1.5" farther away from the plane that the other pulleys rotate on.. it simply won't work. BOTTOM LINE: If you have a 5.0 Tbird, you are better off just buying an underdriven crank pulley for a 94-95 Cobra. FWIW though if you have a Mustang or Capri, these are some nice, solid looking pulleys. I like the fact they are powdercoated black vs. some "look at me look at me" color. ...read more

Performance increase was equal to or better than an electric fan replacement of motor driven fan.

Should include an overdrive for the alternator

Summit RacingSummit Racing Verified Purchase

Caused serious charging issues. Bought an overdrive for the alternator and made it better. Did pickup about 5-10 hp, as I can now pull up the steep hill to my house in 3rd where it kicked down into 2nd before.
