273, could it be a commando and CAM question?

Thanks for the input berlins. Will do a compression test asap.
Kennygene, Two years ago I took it to the strip with the stock converter and 2.76 ratio and no sure grip, takeoff was poor needles to say. Have not had a chance to try it on the strip with the new converter and 3.55 sure grip yet.

Anyone have any input on the cam questions above?
