Again, thanks for all the excellent advice and comments. Some people say that the numbers are about where there should be given the limited info I have and that gives me the comfort I was looking for.

Soooo.... it turns out I had a dead plug. Wouldn't that of shown up on the dyno's computer? Not sure how much a difference that would've made, but ya, there's some lost hp

To answer some of the questions:

The dyno numbers are uncorrected
83 deg F
33% humidity
elevation 103 ft
max hp at 4500 rpm
max torque 3750
No the dyno guy didn't tune it, just fluids
Air fuel line is almost flat after 3k rpm at 13.5

My cousin said "throw on some 906 heads, put 3.91's in it and that will wake that 440 up."

The car goes pretty good, I'm not complaining but..another 75 or so hp would be nice
