ive been looking at some bbk underdrive pulleys...my car is basically stock except l/t headers,o/r x,intake and 3:73 gears, so i wanted to do pulleys next, but i've heard people having problems with them...so are pulleys worth it or what should i do next?

well since you have exhaust and gears.....IMO pullies are more hassle than they are worth so I'd save for an h/c/i.. that's the next step to increase performance significantly for you:D

hell at least an intake and a fuel pressure regulator. and aluminum driveshaft and short throw shifter.

one of my buddies had under drive pulleys and he said they didnt do a thing. he ran the 1/4 without them, then put them on and got the SAME time. some people say they can feel a diffrence and others say they are just a waste of money.

Dont get them, i burned up an alternator within 200 miles of having them on. It will cost you a lot of money in the long run for 1 or 2 horsepower. Save your money for H/C/I

I've had the March Power and Amp UD pulleys on my car for over 7 yrs and I've never had any charging, or over heating problems!

Did they make aBIG difference.. not really.
Did they make some difference.. probably.
