Match Race 1972 ~ 'Duster 340 vs 'GTO 400'

I'm going with the Pontiac on this one.
My wife had a 1972 340 Duster when we married. It wasn't very quick.
Granted, it was loaded every option on it.
With a 3.23 gear, it only ran 15.70's.

I was working for a guy that had a 1972 GTO 400. He had bought it new.
It seemed to be faster than the wifes Duster.
He had never ran it thru the 1/4 for times.
