This creation was one of my favorite trucks to drive. I bought a Volvo with a Boydstun 4-car headrack and mated it to a Cottrell quick-load trailer. It had an electronic 3406 that I had upgraded to factory specs for 550 hp. It just had a nine-speed so it thought my next project was to upgrade to the thirteen but after i drove it I realized I didn’t need any more gears because the powerband on that cat was so wide. I was based in San Diego at the time and even running over the mountains was really no problem with the 9-speed.
I did modify the headrack because those old boydstun four-cars didn’t have enough up travel on position two and three to get a car behind the cab after you had loaded the top when doing four on the headrack. We modified it enough to load 3 ford taurus size cars on the top and still drive a small pickup underneath.
