Which one was quickest in 1972

Hello

The question I was asked was. "If I walked onto a Chrysler car lot in 1972 and asked the salesman for the fastest (1/4 mile) new car they had what would it be?".

Depending on who you talk to the response varies. Some say the A body 340 was quickest, others say the 440 4V B Body ran the lights with a better time. Some even say the E body 340, which I find difficult to believe given it is a bit heavier than the A body. If the E body still had the big block available in 72 then that's believable but as we all know it was not.

Can anyone shed light on this
