The Hot Rod Genesis motor is mine.
They published the dyno output - horsepower and torque - from 3000 RPM to 6200 RPM (peak). We also gave you full cam specs (no secret grinds here), and head flow data from .100 to .800 lift. I thought that we were very forthcoming.

The flow bench was a garden variety Superflow. The dyno was an equally common DTS. No magic, nominal correction only(we're in Detroit, so altitude is a non-issue), and only one full day running on the pump.

Mine was a 505 cid 13:1 flat top, solid roller EFI motor. It made 676 at 6200 (a "peakier" 679 with a 950 HP carb). It runs 10.40s at 131 MPH @ 3600 pounds - so the performance matches the dyno numbers pretty well.

I'm certain that there was more power to be had with tuning and tweaking. Another 30-40 or so seems pretty easy. I am greatly impressed when I see smaller engines with much lower compression, and hydraulic cams make significantly more power than I did. Obviously they have a very well matched combination.
