Are 340’s rare

I'm sure you could make changes to either one to "one up the other" He just said they had identical cams, same compression and were built with nearly identical specs. I think he was pretty disappointed...he is a Mopar guy. It would never matter to me because i don't race. As i said earlier i don't care if your 408 has 100 more HP than my 340. I still don't want a 360 or 408.
These posts always turn into a "my engines more powerful than yours" competition.
