Had a Duster with a heavily modified 360 in it, giant 4bbl, headers, racing cam, driveshaft loop, had to chain the engine to the frame, the works.
Barely idled at a light.
But it was enormous fun giving corvettes a head start, at lights, then blowing their doors off.
I broke the right motor mount and so I could never do another burn out again without the engine rolling hard to the left. I had to use a rolling start, then I could grab 2 and light it up. It didn’t take long to get the rep in High School and soon no one would race me. She didn’t look like much, black coupe with red interior, stock wheels, but only weighing about 2400 lbs with the 4 speed Top Loader and 2:71 rear end it would really fly. I would routinely get 20 mpg cruising down the freeway or back country roads.
I moved over to the Tri-Cities in eastern Washington in 78 but would drive home to Vancouver, WW on the weekends down SR 14 along the Columbia (never saw a state trooper in 7 years on that route) and never drove the Oregon freeway until my wife got pregnant in 1985 and only then because she had to go to the restroom 3 times each way. Fastest I ever made that 200 mile trip was 2hr:40minutes.
