I noticed your profile sez Denver, from my drag racing days I remember how tuff it was to run the numbers at Bandemeire. Do your plugs read good??? What kind of gear ratio are you running behind it??? The cam looks like it has a ton of duration in it. I'm not a cam expert at all, I usually do the tech data sheet on the motor and let the cam company do the reccomendation. Hopefully someone will be along with a more definitive answer.
