Gearboxes

The gearbox from a 1989 F250 with a 5 speed has 5.72:1 first and about .7

Erich

Thanks Erich for the idea but .7 is not a high enough gear, I really need .5 or pretty close. Any other suggestions unless of course other gears in other gearboxes can be swopped into a f250 box to make a .5 ratio

Thanks

Since you wanted 4:1 or 5:1 in first, and would be getting 5.7:1 in first, you could always put this through a diff with a 0.71:1 ratio.

This would give you 4.07:1 in first, 0.5 in first.

In other words, multiply your current rear end by 0.71. That is, if you have 4.11 gears, switch to 2.93 gears.

Thanks Dennis but I would be back to having gears specially cut. I do not think I have a winner here.
