1973 360

I see 2930# for a 1970 /6 Duster compared to 3055# for a 1974 /6 Duster, a difference of 125#. Virtually the same difference between a 1970 Duster 340 and a 1974 Duster 360 at 120#. Before all the nitty-gritty of 4spd v automatic, undcoating (+30 lb!!) or powersteering, etc.

I would have looked at a 2 door sedan /6 car, but they don't list a 2 door Valiant with a /6 in 1970 so I figured the Duster was as close to apple to apples as I could get. I haven't looked, but makes me think they didn't offer a 2 door Valiant in 1970 outside of the Duster. And yes I know the 1970 Duster is badged as a Valiant, I just figured they still had a 2 door sedan Valiant still available in 1970.

Wish they had the Dodge AMA specs, but they don't show them.

i think it was 70 that they didn't make the val in a 2dr?

i'm not much of a betting man, but i'd go a slice of ham that a 70 dart is several hundred lbs lighter than a 74 duster/dart sport

having driven and ridden in both an early 340/727 dart and a later 360/727 dart sport, the earlier car was noticeably faster. not run away and hide levels or anything, but the difference was there. and both cars were fairly similar in build, so neither had an up on the other.

not saying the 360 cars were turds, but they certainly weren't as fast as the early 340 cars.

(and to your earlier point, i'd brook no argument that the challenger was a porker)
