![]() I have the March *Power and Amp* pulleys on my 91 5.0 AOD, and so far have had no problems with them. The only thing I noticed after putting them on was that my car started to run a little hot in 95*+ weather. But thats nothing a 180* thermostat can't fix! As for the hp increase, my car seemed to run a bit smoother, and I could feel it pull harder past 4000rpms. one thing I wouldn't recommend doing is running an electric fan with underdrive pulleys if you still have the stock alternator. You usually need a 130amp alt. when running both.
