I also agree with you, here. Unlike the 440 magnum, which was over-rated horsepower wise, Chrysler's ultimate small block was grossly under rated. The reason is supposedly for the same reason the 383 was under rated: Chrysler mgmt feared buyers would not opt for the higher priced 440 if the smaller engines ...on paper...rivaled the stock 440 as regards power output. Hot Rod dyno'd a stock (but fresh) 340 with X heads and were very surprised to find that it made 385 hp....in stock trim. I was always a huge fan of Chrysler's 340. I simply couldn't choose it as "the best" in this day and age. The high cost of building a decent 340 (let alone finding one that hasn't been raced to death) knocks it from first place, IMHO. Especially considering that BB mopar fans now have a dizzying array of high flowing, cheap, aluminum aftermarket heads available. Something that simply was not the case 20 years ago.
