The LaSalle 3-speed was the transmission preferred for high torque back in the day. Ford referred to their 3-speed as the light duty transmission for pickups up through 1951 or so.

The flathead puts out a respectable amount of torque for it's average displacement and even more when they are bored and stroked. In the early days, a lot of folks just wanted to see how fast they would go and not so much clutch dumping torque events. Those that were too fast on the clutch release were the ones that broke transmissions and rear axles and especially those with the high number rear axle ratios that were popular with the Lincoln gear sets.
