Even though the OF1 has a more lift than a 236/242 Bulter cam, the Bulter cam will make just as much sowing machine noise as the OF1. The OF1 has softer profiles on and off the valve seats. The more aggressive intensity of the Bulter cam is why it is not a good candidate to run with mechanical lifters on Aluminum heads. The OF1 works fine with mechanical lifters on Aluminum heads.

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.
