What is the peak torque of the 357W with GT40 heads and Isky 371252-257 cam?

According to the Dyno2000 simulation table, peak torque at the flywheel is 416 (lb-ft) at both 2000 and 3000 RPM.

What is the peak horsepower and at what RPM?

Peak flywheel power is 278 at 4000 RPM.

What is the maximum volumetric efficiency shown?

The highest volumetric efficiency listed is 77.3% at 3500 RPM.

At what RPM does the engine stop making power in this simulation?

Power and torque drop to 0 at 8000 RPM and above, with BMEP going negative (-12.8 at 8000 RPM down to -78.7 at 11000 RPM).

What software produced this data?

The header shows it was generated by Dyno2000 Version 3.10, page 3 of 5, from the file '357W, GT40 heads, Isky cam 371252-257.dyn'.

This document is page 3 of 5 from a Dyno2000 Version 3.10 engine simulation report for a 357W (Ford Windsor-based) engine build with GT40 cylinder heads and an Isky camshaft (file '371252-257.dyn'). The page, titled 'CALCULATED POWER AND ENGINE PRESSURES,' presents a table of simulated engine output at 500 RPM increments from 2000 to 11000 RPM. Columns include flywheel power and torque, intake manifold pressure, volumetric efficiency percentage, and IMEP, FMEP, and BMEP pressures. Key results: peak torque of 416 lb-ft occurs at 2000 and 3000 RPM, peak power of 278 (hp) at 4000 RPM, and peak volumetric efficiency of 77.3% at 3500 RPM. Power falls off rapidly above 5500 RPM, dropping to zero by 8000 RPM, where BMEP turns negative (-12.8 and lower). A reader can use this table to evaluate how this cam/head combination performs across the RPM band — showing a strong low-to-mid-range torque curve suited to truck use, with the useful powerband ending around 5000-5500 RPM.
