So, if Mopar had simply called the 400 a 383, they might have avoided all the negative stigma associated with those engines, even though there's absolutely nothing wrong with them...hmmm
Yes, maybe the 383M or some other buzzword. 383+ or something..how about 383-S (for Smog) well, at least they called the 360 a 5.9 and not a 5.7! I chuckle when I see a Tundra with a 5.7 call-out (although that is one advanced 350 right there, boy!) a 302 is more like a 4.9 if you round down. Whatever.
