We ran at 29* for 8 hits. Then we dropped to 28* and picked up another 1 mph. There were still a couple of plugs that were on the edge with that tune up. That "baby shot" put the car on the bumper twice at Norwalk this year. Needless to say we didn't jet up that weekend. We needed to get the suspension under control. We ran 145 mph lifting twice on the last run at 28*. That's with the 150 shot.

The magic 27 degrees of timing number (or close to it) also applies to NOS, Charlie. LOL!

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.
