Transmission upgrade options -'70 F100 360 4speed...

[GreyStep]

Thanks for all the input...

I think I will consider changing the rear gear if I want to get a better highway cruise and just make sure the current tranny is well maintained.

I figure I am not going to be drag racing or anything of that sort, just some cruising and the occasional burn out if I can free up a few more Horsepower from this tired 360.
