I own that car several different times, I sold it to Jesse Martinson the first time as a street car. it was a 1970 340 4 speed duster that had been total in a wreck and fixed by the guy I bought it from, he had put a T/A 340 motor out of a stolen T/A that had been burnt., it was minus the six pack and he strip the Duster to lighten it, no interior, single fiberglass bucket seat with a 5 point roll bar, no instrument cluster, radio, heater, no nothing. He raced on the streets of San Bernardino before I got it.
I swap the rear gears from the 3:55 to a set of 4:89 and kick everybody butt in the high desert Victorville, Apple Valley area and ended up selling it to Jesse about 4 month later.
Enough on this, thanks for posting the Video
