Did the 340 really make 275hp?

340 wasnt the only engine underrated. I mean cmon,ya really think the 426 hemi made only 425 h.p? Chrysler was bad for underrating motors,just like the other's. Sure it makes that much h.p,but at 4000 rpm's,lol. Nevermind the fact you can wind em up to 5500 rpm,lol..
