125 HP. Lol. Younger people have no idea just how slow cars were just a few decades ago. Most mid-sized cars in the 50s and 60s had 6 cylinder engines of around 130-140 hp and weighed like 3500 pounds or more. You could get V8s in some cars but most people didn’t. My Dad had a 1959 Chevy station wagon with the 140HP 6cly, 20+ sec 1/4 mile performance. 4000 lbs. Many hours spent in it with the family and a trailer grinding up mountain roads in second gear. Lol.
A 50s era pick up truck would have a very numerically high rear end ratio making freeway speeds near impossible. A friend’s 55 Ford would rap out at about 55mph. You could haul most anything in it though. I think 1st gear was lower than reverse.
Trucks were for hauling stuff not hauling a$$..............
