357W Ford GT40 Heads Isky 371257-265 Cam Dyno2000 Power & Pressure Table

Dyno2000 simulation spec sheet for a 357W small-block with GT40 heads and Isky 257/265 cam; peaks ~294 HP at 4000 RPM and 424 lb-ft at 3000 RPM.

This document is page 3 of 5 from a Dyno2000 (Version 3.10) engine simulation report for a 357W (351 Windsor-based stroker/overbore) small-block Ford engine fitted with GT40 cylinder heads and an Isky 371257-265 camshaft (file: 371257-265.dyn). Titled 'Calculated Power and Engine Pressures,' it presents a table of simulated engine data from 2000 to 11000 RPM in 500 RPM increments. Columns include flywheel power (hp), flywheel torque (lb-ft), intake manifold pressure, volumetric efficiency (%), IMEP, FMEP, and BMEP pressures. The simulation shows peak torque of 424 lb-ft at 3000 RPM and peak power of 294 hp at 4000 RPM. Volumetric efficiency peaks at 80.1% at 3500 RPM. Power and torque fall to zero at 8000 RPM and above, where BMEP becomes negative, indicating the engine cannot produce usable output at those speeds. This data is useful for comparing camshaft and cylinder head combinations for a 351W-based build, as the uploader's album contains similar simulation runs with different cams (Comp, stock roller, other Isky grinds).
