To be honest, I just wanted a half ton. I will not be hauling anything that would exceed a half ton's specs. I like the curves of the older vehicles. I wanted something that was pretty much bolt together which is why I picked an older pickup. It is a pretty truck and she is in good condition for her age.

Thanks for the information.

Cheers Dino

F3 drivetrain

I posted this question along with another on a different thread (F3 Restoration) but it might be more appropriate here. I am restoring a 1949 F3 pickup with flathead V8 engine. The rear end is the 4.86. I was told that top speed on this truck will be around 40 mph with that ratio. Is this true? Should I consider converting to a 4.11?...there is a kit available to do so, I understand.

Carl - I commented on your other posting. Here's Julie's gearing calculator to help you figure out the difference in road speed. Stu

Looks like 55 mph tops with the 4.86 and 65 with the 4.11, engine screaming at 3000 rpm! Thanks, Stu.

Are you all sure about that. My serial number also contains a Y and its an f-2. On the title but also all the specs match the F-2. I read somewhere that the Y denoted 3/4 ton
