My first car, 1965 L320 Datsun Pickup. Got over 30 Highway and had a cute little 60HP tag under the 1200CC lgo..
65MPH with a strong tail wind. had 4.38 axle gears. Weighed about 1850 on the scale at the log scaling station by my house.
Had a little itty bitty 2 barrel carb, Primary was about 3/4 in and the secondary about 1 in. In neutral it would rev til the carb just gave up, couldn't flow enough air to blow the critter up...
