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.
