357W GT40 Heads Isky 371257-265 Cam Dyno2000 Power & Pressure Table
Dyno2000 simulation spec page for a 357W with GT40 heads and Isky 257/265 cam; lists power, torque, VE and IMEP/FMEP/BMEP per RPM, peak 294 HP and 424 lb-ft.
This document is page 3 of 5 from a Dyno2000 (Version 3.10) engine simulation printout for a 357-cubic-inch Ford Windsor (357W) small-block build with GT40 cylinder heads and an Isky 371257-265 camshaft. The page presents a table titled 'Calculated Power and Engine Pressures' listing simulated results at the flywheel from 2000 to 11000 RPM in 500 RPM increments. Columns include flywheel horsepower, flywheel torque, intake manifold pressure, volumetric efficiency percentage, and 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, with volumetric efficiency peaking at 80.1% at 3500 RPM. Power and torque fall off steadily above 4000 RPM, reaching zero by 8000 RPM as FMEP (friction) exceeds IMEP output, with BMEP going negative above 8000 RPM. A reader can use this table to evaluate the powerband characteristics of this cam/head combination on a 357W engine — a strong low-to-mid range torque profile suited to truck use. This is one page of a set of similar dyno simulation comparisons for various cam choices uploaded to a 1993 Ford F-150 gallery.
