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'.
