Idle video of 08 GMC-5.3-H/C

sounds great man! how does it run? with the bigger intake valve and the size of the cam in a 5.3 I would just think your hardly building any cylender pressure to make some torque, you got alot of converter tho, bet she rips hard from 6000-7400.

It does have good dynamic compression and it pulls very well up in the 7200-7400 no problem
