There really isn't enough data to tell the story. We need to see the barometric pressure temp, and fuel data A/F ratio etc. Has the dyno been calibrated, what fuel was used? What carburation was used in the initial dyno run. Was it the same as your run?

The thing that strikes me about your car is the 2.88 diff. I think it had an effect on your rwh. I'm not a dyno guy but it seems like Powersurge hit it on the head when he referenced the 2-3 pulls. Your car (compared to say my car with a 3.54 ratio) is always in 2nd starting out.

Those are respectable 427 numbers. Remember maximum horsepower and maximum drivability are very different things. A little detuning is not a bad thing.
