hey guys, newbies to the forum

got a few queries about Borg Warner gearboxes

first question are the 4spd boxes for a 6 cylinder the same for a Cleveland V8?

also 5spd bellhousing do they fit onto a 4 spd?

thanks

The 250 and 302 single rail gearboxes are the same with a wide ratio spread starting with a 3.06 1st gear and a torque rating of 295lb/ft.
The 351 single rail has a close ratio gear set and a 2.46 1st gear. Torque rating is 325lb/ft.
What sort of five speed are you talking about? The crappy single rail 5spd from the XE 6cyl or the T5 5spd? I think both have the same front bearing retainer diameter so they would slide in but may need to be drilled for a slightly different bolt pattern. Input shaft length on the T5 is possibly an issue too.
