340 actual horsepower

Yes there is a bit of confusion with power ratings because as far as mopar engines are concerned, the power figures given were actually the net power of the engine and not the power measured on the flywheel. From what I read this was some kind of trick to fool insurance companies... anyway the flywheel power of the 340 is somewhere around the 300bhp, as mikedevore said, the 360 is around 330bhp and the 426hemi is above 500bhp!!!

Mopar did and still does rate horsepower at the flywheel. Around 72 all the manufacturers were required to rate them with an SAE net system which still measure the power at the flywheel but included all the accessories (water pump, alternator, p/s, etc), intake and stock exhaust. Prior to 72 they did what ever they wanted, headers, no accessories, non stock air cleaners, what ever gave the number the marketing boys wanted.
