Preliminary head and cam testing

Hey guys! I have been working on the port work and some new cams that are geared toward smaller motors than we are used to seeing in the Raptor race world. The first test is a head change only from stock to a +1 valved CNC port. The blue line is a reference for a stock engine. The gold line shows the torque loss associated with a a Hotcam III, which will be important on the next test. And finally the red is a head change only. I am pretty happy with a near 7 hp improvement without torque loss down low.The first test is a head change only from stock to a +1 valved CNC port.
