I had a new 71 Duster with 3:23 gears and a torqueflite transmission and ran 14:03 @ 101 m.p.h. on stock E70 x14 poly glass tires. Great fun in a plain Jane car.

[@charlesdalton985]

That 340 showed what they are made of, taking on a Stage 1 is tough. And what a great display of torque vs hp, in the first race you could see the Duster coming on and the higher trap speed. Like the old saying goes, “Torque makes power, and power makes speed”. Thank you as always!

GS HAS 510 TORQUE . CAR AND DRIVER SAID : THE STAGE ONE IS THE MIGHEST OF STUMP PULLERS. AND THE ULTIMATE SLEEPER AND HEMI KILLER. . I OWN ONE IN 1978. AND Another IN 1982. FANTASTIC CARS. LUCKY TO BE ALIVE.. WOW - WILD ON WHEELS. SMOKE SHOWS AND VETTE DESTROYER..

[@gary9426]

I think both cars would've been quicker if the Duster had a Torqueflite, and the Stage 1 had steeper gearing. Much respect to the 340s, even in '71 they were still formidable, but tough to take down a Stage 1, especially a '70 Stage 1. Along with the Hemi's and the LS6, they were the pinnacle of power and performance. Another great race!

You'd sure think so! An unusually slow one.

[@bman99ss]

That's the slowest '70 Stage 1 Buick I've ever seen. And with a 104 mph trap speed, the Duster has the potential to beat the Buick to the finish line, but the driver's probably having trouble getting a good launch with the 4-speed.

[@chevyblue10]

The 70s were the best. I was a teenager in the 70s. In the 70s, mid to late 60s cars were behind sold in every used car lot...cheap. Early 70s cars too. I wish I could go back knowing what I know now.

[@calebrose4607]

the Duster was unusually slow for what it was. I've seen a couple of them on your channel run in the 12s, so I'm surprised this one was two whole seconds slower. these were some good races though, don't get me wrong. I'm still happy to see another Duster run down the strip

[@terrybaker1977]

Yep, had a 71 Demon 340, put Edelbrock aluminum intake and a Holley 750 double pump carburetor, a slight upgrade to the cam, and you can jump on it at 10 mph and turn sideways! 12 second car at the track. Probably could have done a little faster, but even with the 60s on the back, I still couldn't get any traction off the line... Love that car, wish I still had it. Back in the day we didn't know what we had. Also had a 71 Torino with a 429, the Demon and the Torino were pretty much neck and neck on the quarter mile..

[@carlbunner5515]

Sure was slow a big part was the driver was horrible. Did you see his start on first race, then a missed shift on second race. No wonder he wouldnt come out for third race.

[@machwind3266]

Yeah, I noticed it smoking bad when it went thru the traps. Didnt come back forthe 3rd round. I think the 340 went ka-poo-ee(!) when the driver missed second or third gear and I think the pedal hit the floor before backing off to reshift. Boom! At least thats what I saw and heard.
