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

My best friend Rick, (RIP) ordered a new 1972 340 Duster, 3.23 SG, 4 speed. We took it to Dragway 42 early spring 1972 when it had about 5000 miles on it..
He only made one pass and it ran 14.51. That was pretty good for a totally stock 1972 car except for G70-14 Pokyglas tires on the rear. His mom had a Goodyear credit card, LOL.
My 1970 Swinger 340/3.55/4-gear, went 14.4 at a tic under 98, with 12,000 miles on the clock, on the E70-14 Polyglass tires it came with. It weighed 3330 with me in it. Daymn that car was light. Also 1-pass only.
Yur right about tires; from fall of 1970 when I bought it to fall of 1974 when i parked it; it had gone thru 7 sets of rear tires. That beast laid rubber in three gears, for hundreds of feet.
Not to mention she was on the second engine, second trans,second rear gear,second driveshaft, multiple clutches, second set of shocks,and the usual assortment of alternators, starters,water pumps , and such; and she was banged up pretty bad.
I remember the kid who came to buy it in the spring of 75. He offered 1300 and I accepted. Just about 4 years earlier I had paid 2800 for that ill-handling,over-powered , trouble-making, pos car. We had to tow start it, before he arrived, as the starter died just prior to his arrival. "Whatever you do" I told the kid, "don't stall it",lol.
Good riddance to the "pink dink", hyup Panther-Pink.
I never saw it again.
I was just going on 21 an a half years old.
