Tulsa bought 2 440 pursuit Plymouths in 1968, were gauranteed to do 186 mph if kept tuned. I got pulled over in 1968 by a hiway patrol in a 68 Plymouth fury, had to set in his car while he wrote the speeding ticket(90 in a 65), his car set and shook and loped like a race hemi about to die, don`t know what it was, but he was on me quick-after passing him at 90, w/ him setting parked on a side road. COST ME A HUNERT DOLLAHS !
