What engine combination does this dyno chart show?

A 357W engine with GT40 heads and an Isky cam, from simulation file 371252-257.dyn run in Dyno2000 Version 3.10.

What is the approximate peak horsepower shown on the chart?

The power curve peaks at roughly 275-280 HP near 4000 RPM.

What is the approximate peak torque shown?

Torque holds around 400-410 ft-lbs from roughly 2000 to 3500 RPM before declining.

What software produced this chart?

Dyno2000 Version 3.10; this is page 5 of 5 of the printout.

Over what RPM range do the curves show meaningful output?

From about 2000 RPM up to roughly 7500-8000 RPM, where both curves fall to near zero.

This document is page 5 of 5 from a Dyno2000 (Version 3.10) engine simulation printout for a 357W (357 cubic inch Ford Windsor-based) engine build using GT40 cylinder heads and an Isky camshaft (file '371252-257.dyn'). The page contains a combined power and torque graph plotted against engine RPM. The left vertical axis shows horsepower (0-1000 HP) and the right vertical axis shows torque (0-1000 ft-lbs); the horizontal axis shows RPM from 0 to beyond 10,000. Two curves are plotted: the torque curve starts near 410 ft-lbs around 2000 RPM, stays roughly flat through about 3500 RPM, then declines steadily to near zero around 7500-8000 RPM. The power curve rises from roughly 160 HP at 2000 RPM to a peak of approximately 275-280 HP near 4000 RPM, then falls off, reaching near zero by about 7500-8000 RPM. A legend identifies both curves as belonging to the '357W, GT40 heads, Isky cam 371252-257' simulation. A reader can learn the simulated power and torque characteristics of this engine/cam combination and compare it against other cam options in the same album of dyno printouts.
