My brother got a new best. He never posts on here so ill do it for him. His setup is a 2000 black rcsb with a lq4 243 heads ls6 cam mp112 2.8" pulley 9# boost 4.56 gears with a t56 manual tranny. Ran a 11.77@121mph 1.68 60ft first time out on the track with the new setup still needs to be dialed in some more.
