1968 '340' Barracuda vs 1968 '383' Road Runner

i'm not embarrassed... & i dont think you checked your data too well.

the 383 A bodies i'm pretty sure ran 13.9's
the 440 A bodies ran around 13.3's
the hemi A bodies ran at least 10.5's i'm not sure about the 10.3 but i think that was reported. maybe someone cheated lol.

the 340's best time stock in an A body was in the 14's


This is the proper comparison if you are trying to make a point about the motors. Comparing one car to another is a simple lesson in physics not a comparison of motors. The OP seems to want to judge the 383 based on its performance in a bigger car and the 340 based on the lighter car. They put the 340 in the roadrunner in 71 so how was a 71 383 compared to a 71 340 roadrunner. Or how did the 68 383 barracuda run compared to the 340? Both with similar gearing and transmissions. That is a wayyy better judge of the motors.
