Darby, This printout was of the 6th and final pull. I definately agree, 650 is not enough. I have a q-jet that Cliff rebuilt a few months ago, I'm pretty sure is 800 cfm. That's what I'm planning on running on the engine, at least for a while. If I feel it isn't performing at the track, I'll get a holley dp, probably 850. Total timing was at 32 degrees, seemed to be where it ran best.
I too felt like the HP peak was pretty early -earlier than I expected. I thought it would peak in the 5000-5300 range somewhere, but obviously that was not the case. (I thought, overall, the powerband was fairly good and broad, at least within the dyno pull's rpm range.) Honestly, I thought it would be normal for torque to start tapering off like that after it got up into the rpm range... I guess i was wrong?

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.
