Your combo looks like it should be going faster than it is. Look at 383man's combo, he's got a great old-school combo putting down excellent numbers for a street/strip car. Nothing fancy there except for some well matched components.

Maybe that cam of yours is hurting you. You say it'll diesel if you run on 91, and with all that duration that makes me wonder. You've got enough duration, but on that 112 lobe seperation you are hurting your top end/mid range.
