travis, if you want to mod then do a bunch of research. you are really going to take a chance no matter what you do, in my opinion. i learned a lot reading this board and people here helping me along that know more than me. however, there is still conflicting info from even the most knowledgeable people which leads me to believe it really depends on the car you have in the end. what works on one might not work on another. slick2500 questioned my 3.5 pulley info that i've gotten from research. we should all appreciate that people are looking out and i would hate to steer anyone wrong.
