I recently have been buyin' stuff that i would not normally buy for the truck. And one thing that has cross through the ole noggin are those controversial (problaby didn't spell that right) ASP underdrive pulleys, i have noticed not many guys here have them and there has to be a reason behind that. I don't mind the $200 if it is a good product. If it only is 5-10hp who cares it is 5-10 hp that i didn't have before. I know money can be spent wisely somewhere else, but I am already in the process of the whole cam, stall, rods, springs, retainers, shifkit thing. And i wouldn't mind a little horsepower now.
How do you guys feel about this product?
