Front to rear spring swap on ZJ, opinions please?

I have heard of this swap and seen a few kits advertising this. I have a bunch of extra springs laying around and thought I might play. Since I know that I can acheive 6"+ of lift with a short arm setup, I am thinking of this swap with a 5.5" lift spring up front. My main question is I have a V8 and I know the front spring rate is different. How much lift will the V8 spring give me in the rear? Or should I just use a I6 spring? I have heard I can get 3.5" out of the I6 spring. Any help would be great.

uhhh i hate to clue you in but this is the xj/mj forum i don't know zj's but these people might

Sorry, they allow ZJ's (Grand Cherokee) on here last time I was here. It may have changed though. Thanks for the other site looks great.

we didnt say it was totally forbidden, some ZJ stuff is interchangable with XJ/MJ stuff.
we wouldnt mind helpin you out, but a ZJ, from the motor and front axle backwards, is totally different than an XJ, so we might not be of much help.

my buddy got about 5.5 or 6" on the V8 front coils

Thanks guys. I have an MJ and an XJ too. Also I know you guys combined have a vast knowledge. Thanks again.
