Early 72 340, is this one of the de-tuned ones?

Just for comparison purposes, in 1970 my '69 Swinger 340 w/727, non-sure grip 3.23 rear, ran 14.28 @ 98+ mph at OCIR here in SoCal. Tires were G70-14 Goodyear Polyglas.

that is a decent time for the day most the 340's i knew ran 14.4 or so depending on driver of course
