Hey guys, I know a few guys asked about the HT1 cam in a 4.8. Heres a idle video with stock manifolds, stock cats and a flowmaster. I dropped 1.1 seconds and gained 5 mph in the quarter with the cam. Im going turbo, so i didnt do a stall with it, no headers and still have 3.42s on 20s. It really picked up in midrange and top end over stock. Drivability is awesome and I cant complain about the performance for what it is at this stage.
Headphones really bring the video to life, sounds better that way.
