When you look at the rear wheel hp, they do seem low, but if you recalculate like I did for you, numbers are good. I made 585 fwhp @ 6,000 rpm. with an engine with a lot more work on than yours and am very happy. Mine is a 27 with a 28 crank (454 inches) about $2,000 worth of porting and a bigger cam (.620 / .626 lift, 258 / 260 deg. @ .050). This is a pump gas motor, Edelbrock was very impressed with these numbers.
The other thing that most people don't realize is how bad stock side pipes are. Cut out the muflers and replace them with a set of Dyno-Max's. A 50 hp jump at the rear wheels would not suprise me.
