Installing my d1sc. 4.5 upper and 7.25 crank pulley
I bought a kit used on here and currently installing. I spoke with Bob at Brutespeed (crazy awesome service) and purchased my remaining parts from him. My question is that this setup came with a 7.250 crank 8 rib pulley. It bolts onto the ati balancer no problem. I have searched and cannot find any info of anyone running these 2 pulleys. I need to know what belt to run and how much boost this combo will make on a basic bolt on ls1. My goal is 6 to 8lbs. Thanks for any help

Once you fig out belt size, save yourself a lot of headaches and get a gates rpm belt . They won't stretch like the others . I would just put it together and run a rope around the pulleys . Measure rope , convert to mm and you should be in the ball park. Buy a few different sizes and go from there . You can return what you don't need . Once you have the correct size , get an rpm belt . Did you ask bob?
