It is a simple matter to run numbers through the formulas.
Back in the 50's, Lawson, Bradley, Chrisman, MacDonald and others were
all running in the mid 140's and high 8's. It takes about 400 hp at the flywheel to do this in a 1200-1300 lb car.
Assuming a dyno has been calibrated properly, a steady honest reading of 400 can be flash read easily at 435. A common practice especially in the "olden dayz".
A couple of the old timers that ran in the old days are on this forum.
Ask them how long rods and bearings lasted with 100% nitro. You will find it was quite awhile comparatively speaking.
