z-ing my frame

[wig]

I want to z my frame on a 67 suburban.I tried using search first couldn't find anything. what I'm trying ti find out is if I z the front.Am I gonna have to cut the floor for the trans.thanks for the help.

how big is the Z?

It also depends on which transmission tunnel you have (3 spd or 4 spd).

I think its 3 speed.how much more room will a 4x4 hump give me.so I can put as much of a z as I can.

A 4spd hump will give you more room. you only need to do about a 2 inch Z to lay the truck flat if you are going to bag it. You should be able to do a 2 inch with a 4spd hump, no problem. But you will have to make a tunnel for the driveshaft.

Or use the 2 piece driveshaft should help with the driveshaft issues.

it has a 2 piece.I gonna need a hump then.as far as the tunnel I guess I'll play that by ear.

I have a 72 burb with a 2" raised x-member( I know not a z but since the questions are driveshaft/trans hump related)

I had the low hump and had to cut out for my trans. My driveline is super close to the floor and may now need a tunnel. It didn't before I removed the body but it was close enough to make me consider one. I'll know more once I put the tub back on. I removed the body to work on the rear notch/4link.
