Trans swap Qs

What all would be involved with swapping a NV4500 5-speed O/D transmission inplace of a 700r4 in a 2wd 85 chevy?Has anyone done this swap(pictuers are awesome)? I know I would need a high hump trans tunnel,clutch master cylinder/slave cylinder and appropriate lines, clutch pedal is that all or am I forgetting something? Is the speedometer driven by cable or electronic? What would the approximate improvement be in gas milage or would that depend on engine?
Thanks

Some info here. http://www.high-impact.net/transmiss...Configurations

I have never heard of that swap. You could probably raise your hump by using a bolt-in hump out of a 4WD truck.

Re: Trans swap Qs

Yup 4wd hump would work. Would I have to move trans crossmember and would driveshaft length be different?
Thanks

No idea, but if you can find the length of that transmission somewhere on the web, you could compare it to yours on this chart:
