1.6:1 Rocker-Arm Comparo
What’s in a Number? More Than You Think "...deflection present in the body of the rocker arm and the pushrod, as both flex under the load of the valvespring, the stresses of harmonics transmitted throughout the valvetrain, and elevated engine temperatures." https://www.motortrend.com/how-to/hr...r-arm-comparo/ I've seen flow bench testing on a set of SD Performance KRE D-port 300-305cfm CNC ported heads. Tested to 0.600" lift on the intake with the numbers increasing. Most all the ported aftermarket alum cylinder heads flow well above 0.600" valve lift. .

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
