*Increasing Valve Lift for more HP/TRQ
I remember years ago, changing the rocker arm ratio from 1.5 to 1.65 provided a decent HP/Trq gain (20hp) for a reasonable cost... I am not sure what it would take in a 2012 3.6 engine due to its complexity.. I'm just throwing this suggestion out there.. I feel this could be a very popular mode if someone with the rights means could dyno test it.. The 3.6 camaro world would also benefit as well. So there is defiantly money to be made here.

Re: *Increasing Valve Lift for more HP/TRQ
These are overhead cam engines. The only way to get more valve lift is to put cams in it.
