I think there was a little miscommunication. I never expressed a negative attitude toward 340's, and I didn't call them crappy. I love 'em. I said a crappy 340 (listed at 240bhp) compared to a good one (275bhp), meaning only the differences from the years listed above. They're a great motor and I'd rather have one than a 318. Just the same, according to the numbers given, which I said probably have problems with their accuracy, the lower horse (crappy) 340 is practically on par with a good 318 (230bhp), compared to a 318 from a crappy year (150 bhp). Please note, it wasn't my comparison, but I cited the source, and said there are probably problems with the numbers, unless you meant that the mild build I suggested wouldn't hit 300hp, but I think it will. It just seemed like my post was taken wrong, and I wanted to point that out. Hat's off to 340's and 383's...but also to built 318's.
