Pullies(sp)

It is well known in this forum that pulleys have no effect on this engine. But just for laughs and giggles check out Racer Walsh for them, then decide if you want to shell out for something that may net you a performance gain you can't even feel.

I supposed underdrives might be worth the money on a high-horsepower turbo car, but I would gather that even then they would only be worth a few ponies.

I never really understood why underdrives are worth so much power on a 5.0. In contrast they are worth little to no power on the '96-04 4.6's, and yet on the '05's they pick up around 10 hp. Kinda weird.

Anyway, yeah they really aren't worth the money, especially considering that you get 2 pulleys for $100 whereas a 3 pulley set for the 5.0 is less than that. Plus, the pulleys aren't even a matched set, they don't look that cool (for being aluminum), you don't get a water pump pulley, and the crank pulley doesn't even have a damn timing mark on it (guess how I know)
