Most don't need a new belt, you other mods will vary the amout of hp you will see. 7 is probably possible with stock engine. One or two of them is 'left handed' which means you turn it the other way than your used to.

Well I'm guessing if your belt is too long now it definately won't fit with the UD's. I needed a smaller belt...

I tried just using the crank and water pump pulley and the stock belt wouldn't work. Got the alternator one put on and it fit again. Felt a little power gain, but it was probably the last power mod that I've done in a long time.

i cant wait to install my march underdrive pulleys. what bolts did you guys use? stock ones?

on the March pulleys site they have an article from 5.0 Magazine saying they got a gain of 15 hp at the wheels

http://www.marchperf.com/superford1.html

not only do they perform, they look good too.

Stock bolts are all un need, I doubt you'll get as much as fifteen.

I gained absolulty nothing with my pullies ASP alumiums. I got 0mph dropped 0 tenths and gained 0rwhp. I dont know how some people get 3 tenths or soemthing. My guess is that the weather was different of they just hit a good run.

I dunno bout all that. Maybe a little leak on the front end....

Maybe i just needed a new belt with the UD's cuz I had previously done the smog delete. I dunno, stupid BBK's.

The crank pully is flat? maybe you got some 87-93 ones instead by mistake?.
