Easy HP and torque increase.. With a Stock Camshaft, or even most aftermarket Camshafts. I do all the work, and you just bolt it on !! AdjustED Cam Gear ( ACG )

Nice! I've been happy with my head you guys built for me!

Thanks... It is amazing how much MORE power is in just the Cam Phase.

Have fun...
