sqaure body suburban help

i just picked up a 1985 sqaure body suburban, any help would be amazingjust wanting to get it to lay frame on stockers or my 22inch intros off my 72 blazer,will a 3 inch z on factory arms lay out? also how much will i have to cut up the trans tunnel with a zid like to do a 2 link for the simple fact that its simple and can save floor space in the back, im trying to do a simple budget but im fighting the fact of wanting a porterbuilt setup,

also with the fuel tank, have any suburban guys on here used the factory tank and just raised it?

It'll lay on 24's with a 3" z and factory arms. Tunnel just needs to be cut over the bell housing and tranny body. Factory tank will work fine. The big one (33 gals i think) would have to be raised but the 25 gal? won't.

okay ill have to look into tank size,
thank you so much
only other question since i cant get a straight answer are truck leaf springs the same length as suburban leaf springs?

stock floor while your at it or you'll regret it. You're half way there Z'ing it.

I kept my factory tank, just raised it. you'll have to raise the tranny tunnel anyway even if you stock floor it. I used the dropmember, so i can't help you there, but i've heard the 3" z is fine. Welcome to the wonderful world of square body subs!

i might cut the bottom off the frame but thats all i dont wanna build a full frame for this, id love to do a dropmember but just to much money right now.
im researching right now how much of the floor i need to cut, then whats the best plan of attack if i should just try and drop the motor down two inches or leave it alone with the z,
im excited to have a bagged suburban though, i just totally grew out of mini's lately

laid out burbans are the shit!!! badass lookin ride plus you can still tow likea mutha if you set it up right :TUP:

that was the main point, i wanna keep it simple but still tow my camaro to race events,
just trying to figure out now my best plan of attack to do the rear end

my 92 has a 3 inch z and is stock floored had to relief cut the floor for the trans and had to build a full driveline tunnel. also 2 linked mine to save the floor and the bars come thru the floor just a little under the backseat. i know mines a newer body but hope this helps to convince u to body urs while ur at it...
