I remember when Dulcich had a monthly column in Mopar Muscle. I used to love the comparison tests and sleeper combos he did. One thing I remember is that the 340 seemed to love bigger carbs. Throw the carb size calculations out the window and run a T-quad.
I always said the 1971 340 may have been the best in an A-body. It still had the high compression and an 880 cfm carb when needed. The AAR T/A may be rated higher but they were in a heavier E-body. My best friend Rick ordered a 1972 (first year for low compression) 340 Duster, 4 speed and 3.23 SG. We took it to the track in the spring when it was new and it ran a 14.51 on its only run. RIP Rick, Vietnam vet who died of cancer 10 years ago.
You know, many years ago I broke down the numbers on the 340 and 360. I examined all the horsepower and torque figures gross and net. I discovered the 74 -360 made more power than the 340 and these numbers show the same story. Except for 71 but my numbers showed more torque for the 360 even over the 71. Don't want to start the 340-360 debate but it's interesting.
The Duster 360 did a number on those in the NHRA 'Back-in-the-Day'.

1975 ..... SS/LA

The NHRA did their best in trying to squeeze {Horsepower change} Judy out of Super/Stock each year by upping the 360's Horsepower factor.
