This document is page 5 of 5 from a Dyno2000 (Version 3.10) engine simulation printout for a 357W (stroked Ford 351 Windsor) engine build with GT40 cylinder heads and an Isky camshaft (file 371257-265.dyn). The page contains a single power and torque graph plotting Power (HP) on the left axis and Torque (ft-lbs) on the right axis, both scaled 0-1000, against engine RPM from 0 to about 11,000. The plotted curves show torque starting around 410 ft-lbs at 2000 RPM, peaking near 420-425 ft-lbs around 3000-3500 RPM, then declining. Horsepower rises from roughly 160 HP at 2000 RPM to a peak of approximately 290-300 HP around 4000-4500 RPM, after which both curves fall off, reaching zero near 8000 RPM (indicating the simulation's cutoff). The legend identifies both curves as belonging to the same simulation run: '357W, GT40 heads, Isky cam 371257-265.dyn'. A reader can learn the simulated power and torque characteristics of this specific engine combination, including approximate peak values and the RPM ranges where the engine makes usable power. No fuse, wiring, or vehicle-specific applicability data appears; there are no exact numeric tables on this page, only the graph.
