Chrysler (Direct Connection) rated the 440 4bbl (no year specified) at an estimated 270 to 330 hp. FWIW

That would have been net horsepower at the flywheel; gross would be higher - although not necessarily as high as advertised horsepower.

Hot Rod magazine dynoed a 67 383 4-barrel back in the day. Advertised horsepower was 325. They got 280.

Yes, I think you're correct, net, not gross.



To me, wouldn't gross be at the flywheel and net would be at the rear tires?
