I am putting together an ls2 with an F1 procharger, I need to know the part number for the correct ATI balancer. The accessories are 05 corvette, and I need an AC pulley. The balancer needs to have the correct amount, size, and location bolt holes to accept a procharger 12 rib pulley. The part number for the non procharged ATI ls2 corvette balancer is 917266, the style im looking for is similar to 918853 (f body balancer with procharger). Anyone run this combo before? ATI website, catalog, no listing. Called Summit and Jegs, no answer. I know I can wait until monday but im hoping someone can give me an answer sooner. Thanks
