What peak horsepower does the 357W with GT40 heads and stock truck roller cam make in this simulation?

278 hp (flywheel) at 4000 RPM according to the Dyno2000 calculated table.

What is the peak torque shown for this 357W combination?

425 lb-ft (flywheel) at 2000 RPM, staying above 400 lb-ft through 3500 RPM.

What software produced this power and pressure table?

Dyno2000, Version 3.10, as noted in the page header.

At what RPM does the simulated power drop to zero?

Power and torque are shown as 0 from 7500 RPM through 11000 RPM, with BMEP going negative (-2.1 at 7500 RPM).

This document is page 3 of 5 from a Dyno2000 (Version 3.10) engine simulation printout dated 2-7 for a 357W (stroked 351 Windsor) engine build with GT40 cylinder heads and a stock truck roller camshaft. Titled 'Calculated Power and Engine Pressures,' it presents a table of simulated engine data at 500 RPM increments from 2000 to 11000 RPM. Columns include flywheel power (hp), flywheel torque (lb-ft), intake manifold pressure, volumetric efficiency percentage, IMEP (indicated mean effective pressure), FMEP (friction mean effective pressure), and BMEP (brake mean effective pressure). Peak torque is 425 lb-ft at 2000 RPM, and peak power is 278 hp at 4000 RPM. Volumetric efficiency peaks at 78.5% at 3500 RPM. Power and torque fall to zero at 7500 RPM and above, with BMEP going negative beyond that point as friction losses exceed indicated pressure. This data lets a reader evaluate the low-RPM, torque-oriented character of the stock truck roller cam combination with GT40 heads on a 357W, useful for comparing against other cam options (Isky and Comp Cams profiles) documented in companion pages of the same set.
