Cam + ARH Headers LS3 498.2 RWHP https://ls1tech.com/forums/generatio...er-street.html ^First thread with Low Lash Solid Roller No Header.
I just picked up my car from Lethal Racing. They installed my new ARH headers
and a new dyne tune. Picked up 63.7 RWHP with the new headers. While I was there Nick checked to valve lash after 1500 miles no adjustment needed. Engine HP showed 572.9 so thats about 142.9 over stock. After headers RW 498.2 HP 459.5 TQ I think that's good.
