Actual Horsepower Of '60s/'70s Muscle Cars

[Fleet 500]

Bone stock 426 Hemis made about 315 rear wheel HP, which lines up quite well with Chrysler Corp's 350 SAE NET HP rating (at the crank)

Is the 315 hp from a "formula" or an actual test? Yeah, a manufactuers "official" rating. We all know how (in)accurate those were! Meaning since they underrated the gross hp, they most likely underrated the net hp!

Here's what 425 ACTUAL (SAE NET) HP looks like in a 4,212 pound (PLUS driver) Chrysler sedan: 173 MPH.

Interesting but I'd much rather have a 170+ mph '69 426-Hemi Dodge Charger Daytona.
