What was the largest stock gear available from Chrysler on the 1970 340 Duster/Dart? 3.55 or 3.91?

Wasn't it 3.91 with a stick and 3.55 with an auto?

3.91 could be ordered with either.

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.

3.91 could be ordered with either.  1970 A-bodies:early in the model year the 3.55s or 3.91s were a gear ratio OPTION by mid-year the 3.91s became the A31 "AXLE PACKAGE"

I had nearly option-less 69 Cuda, 340 4 speed, 3.91, w/ M&H Racemater street tires. From a 1/4 mile stand point, probably one of my slower muscle car's. But from 0-30 mph, it would loosen your fillings. Completely wore out front shocks, clamped rear spring with a snubber about 1/4" from the floor board. I'd side step the clutch at about 5000 rpm, the car would shudder, the front end would lurch up, the mirror would swing back, and the ash tray would flip open. One of my most fun cars to drive.

Interesting... I didn't realize you could get a 340 in a Valiant. Yes, but it was ONLY in a Duster  correct... same than the Dart, just the Swinger! lets see, Those were the only 2 doors available on each brand by 70. Swinger for Dodge and Duster for Valiant. On 71 both increased the 2 doors offer taking the model from the other. After this, the Performance was optioned just on fastbacks, not anymore Swingers 340

My 1969 Dart GTS 383 4 speed car came with a 3:91 741 sure grip when it was made in October of 1968.
