There were also several 389 Pontiac wagon combos that set quite a few records.

And, of course, their were lots of GTO's that set records, and won races. Knafel Pontiac & Royal Pontiac are 2 dealers that campaigned Pontiac drag cars.

And, when the Firebirds came along, they too, set records and won races. But, some of these feats came along after your cut off date of '71.
