threw the fairmont and dons notch on the dyno

Donovan swapped out his truck intake for a ls6 intake, picked up 40rwhp, then we bumped to 22lbs of boost and made 607rwhp, awesome.



I made a pull on 18lbs and made 585rwhp, we think the 706 heads on these 5.3s suck, so we are gunna try swapping out the heads on my fairmont and see if and how much it picks up.
