okay i know stupid question but wanna make sure...im gonna be swapping to a 5 speed and changing out my rearend to posi as well as doing a 383 build...just wondering if the auto gears will be able to be used with the manual... aka switch gears in the rear ends

umm....okay but not my question..thanx though...im swapping rear ends with a 95 lt1 from a 5 speed... now correct me if im wrong but a manual has smaller gears... 2.73 i think. question is can i keep the 3.23's from my car in conjunction with that rearend and the manual transmission... aka swapping out for larger gears.



i have an automatic by the way

well i put a posi rear end from a auto on my car when my rear end died. seemed to work well for me, i've got faster take off, and no problem spining 1,2, and part of 3rd when i get on it. AJ

Depends on the manual...

alot of manua;ls came with 2.73s, and some came with 3.42s.

The rear axle off a z28 will jsut bolt in if oyu want to do the entire swap and everything with brake conversion.

i did the z28 rear axle swap, worked great, and I upgraded my stock 3.23s to 3.42s.

I assume you mean to swap a 6-speed not a 5-speed, if you plan on putting a Borg Warner 5-speed thats found in v6s behind anything with any torque, you are asking for trouble.
