Torque through driveline losses

Those numbers don't make sense at all, sorry.
If you apply the simple math and count whatever percentage on top of your numbers, say 18% for drivetrain loss, you'll arrive at a 410 making roughly 420 horses and 625 ft lbs of torque. No way.

Why is it so impossible to believe? Those numbers are similar to the numbers my 408 Magnum recently spun out on our local chassis dyno. 382 hp & 525 ft lbs of torque at the wheels.

A well tuned injected 408 with ported big valve aftermarket heads, a well-matched roller cam, 10.2 to 1 compression and full TTI 3" exhaust makes an efficient & surprisingly potent street motor. Especially when coupled to 3.90 gears, an automatic with overdrive and a properly set-up rear suspension with drag radials..
