Christmas continues for MOPAR rsacers

What I don't understand is why this is specific to a 1969 & 1973 Dart (only)? I
As far as I know, the 1967-1971 318 2bbl is identical from year to year. If not 1967-1971 at least several years are identical with the only deviation possibly a carb?
And the 1972 318 2bbl is the same as a 1973 2bbl (and possibly the 1974 318 2bbl?).
And why do Dart's get this new HP and not Valliants? Seems to me this should be all "A" body's with 318 2bbl's and auto trans; with the higher compression pre-1972 separated from the lower compression 1972 engines and later with similar specifications.

Last year when the 69 lost 3hp I questioned this and here is the response I got ...

.Sam,

The 69 and 73 are different in that they use different intake manifolds, different combustion chamber volumes, different deck clearances, and different head gasket thickness'.

Probably what happend was in 68 was the first emissions regs, and downward since then. I have the parts books back to 1960 if anybody needs something looked up. They are the old paper books, therefore I can look up stuff in them. On the computer, I am not allowed to learn to look up stuff. I really don't understand that, but then again...........

Then I stand corrected. If those engines are unique, then they should get unique HP adjustments.
And after looking at the class guides, the 1969 318 was reduced in all models, not just Dart. So if you have a Coronet, Swinger, Dart, station wagon; whatever, the 318 2bbl is now 172 HP.
But the 1973 was Valiant / Duster / Barracuda & 'Cuda only and not the rest of the larger car line.

Now you want consistency out of this outfit, for all the money spent? Jeez!
