Transmission quirk
I hava a 64 f100 with a 292, four on the floor. When in nuetral, when I let out the clutch, the truck wants to move forward. Not much, and it generally does not move, but you can feel it trying. Today it did roll forward some. What could be causing that if it is in nuetral?

I assume the linkage is external on that vintage. If so disconnect linkage rods from the tranny and see how the neutral detent feels for each lever on the tranny...move them back and forward until you feel the neutral detent (chocking wheels and such for safety of course). With the linkage disconnected: if it no longer feels as if it wants to move adjust the linkage rods to match the lever positions on tranny: if it still wants to move then the problem is internal.

cab mounts
Thanks Gavin,
The part about checking the cab mounts rings kind of true on this old thing as the rear mounts are in bad shape due to rust. I need to rebuild the weld brackets on the bottom of the cab. I guess I need to check both ideas out. Thanks for the advice.

If your buddy is still alive and was able to stop it with his hand, then you are dealing with friction.
With the input shaft spinning in thick oil, some energy is going to make to the output shaft.
You might check the oil and make sure it is still oil, and not more like tar.
Put another way, if there was any mechanical connection due to a shifter issue, your friend would be dead and you would be in General Non- Automotive asking about burial plots and liability lawyers.
There is a blown up illustration of the trans here, you can see how the input shaft sets things in motion in the box even when the gears are not engaged.

Tar pit
Well, that would be an embarassing fix it turns out to be the problem. I just got the truck a couple of weeks ago and have not checked the tranny fluid yet. I will definately check it out. There are a lot of great minds on this site.

This may be a little off the topic but I have a 3 on the tree in my 63 f100 223. If I pt a 4 speed on te floor would I have overdrive at that point or are the gears in a toploader 1-1. I am thinking about putting a 4speed in on floor but not if it wont give me beter rpm at higher speeds. Thanks

There may be a tranny out there with overdrive from a car that will fit a 223 but I do not think you will find one in a 4 speed on the floor from any truck.

A truck 4 speed with the low first gear would tolerate a taller rear axle ratio, giving you similar results.
T98 will bolt up, T18 may bolt up, T19 can be made to bolt up, T170 (the OD trans) again needs to be drilled. Input shaft length needs to be checked.
