My '55 1st has a 270 and SM420, so I have the granny-gear first option when I need it. I also have 3.08 rear gears and would agree with those who say its drivable but no longer a good choice for towing heavy stuff.

I've pulled a loaded car trailer with it. Once. The brakes aren't up to the job, and the truck doesn't have a brake controller. It did the job but didn't seem real happy about it.

I find the long-stroke six deals real well with the low gears. I have a v-8 powered car with a 4-speed and 3.07 gears. When I get out of the truck and into the car I've stalled the car starting out a few times because it needs more throttle to get into motion.

Somehow its never occured to me to even try towing a trailer with the car.

It's true. I really don't do anything but browse the Internet looking for trouble...
