I believe good believable power numbers for the XV 400 with these cams are:

•Pontiac 066 Cam – 330 hp at 445 lbft torque
•Summit 2800 cam – 340 hp at 440 lbft torque
•Summit 2801 cam – 360 hp at 430 lbft torque (actual uncorrected dyno values)

…with 10.0 to 1 compression and a careful rebuild with torque plates and quality components (pistons, rings, bearings, etc.).

Thanks for following along! It’s been a rewarding journey so far and next spring will tell how it actually performs at the dragstrip.

About Us

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.
