Pulleys - How much gain?
I was wanting to put a underdrive pulley kit on my car(91), but was wondering how much gain would I get from this or is it even worth the hassle? Also wondering where to get a good set of pulleys? 
TIA

I didn't measure any hp gain though the engine seems to spin up a little quicker, especially in 1st gear.
March (Summit Racing) makes a Power & Amp pulley set that includes an under drive crank and an over drive alt pulley. Though I have the powder coated steel pulleys, I think the coated Al units might give a little better results.
When you install these pulleys it's a good opportunity to also discard the frisbee from your water pump pulley.

I have heard an underdrive pulley set is good for around a .10 in the 1/4. When I did the march power and amp set I was suprised at the gain I felt, I wasn't expecting much at all. It seems to pull much harder thru the rpm range

Does anyone know if there is a difference on the LT4 engine? I wasn't considering it, but good info none the less.

I installed a set on all the cars I have owned and have definately noticed a low end difference. The largest diff was a 2.59 car that couldn't squeal tires before to being able to do burnouts after. I have used the 3 pulley sets and have never had an overheat problem. Bang for buck I say they are a good deal. Headers rank right up there too.
