The Summit line of camshafts, as good as they are, are NOT the same/comparable as/to the Pontiac OEM grinds.
Summit cams got less LSA, more lift, less overlap and less time on the lobes. And for the McKellar #10, they have even more squared lobes than the #744, with the RAII/IV duration at .405" lift and 1.5 rockers. http://www.wallaceracing.com/camcode1.htm http://www.pontiacpower.org/PontiacCams.htm http://www.classicalpontiac.com/restoration/cams.html |

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.
