Doing the 7.5 to 8.8 conversion
 

I'm planning to swap the old 7.5 to the better 8.8 and myself a lil trac lock limited slip diff. Goin with 4.10s.

Found this 8.8 on the net http://www.kmpaccessories.com/mugt88reax05.html

I'm planning on this diff

any ideas on what I may need for the full conversion or am I heading in the right direction?

Why?

Are you really going to need to change the rear?Are you going to add enough power to justify the swap?

Not trying to bash the V6 but to me unless you are going to push enough power to need the swap I would use the money for something else.

im goin with the vortec supercharger or Xcharger(cant decide yet) come Feb...so im thinking this is justifiable...if not would it be suffiecent to just change the diff?

haha, well this is my lil project car. And well bein in the Army doesnt give me alot of money for the GT..haha
besides, no credit is worse than bad credit haha.

You don't need to buy a posi it already comes from Ford with one.

then why am I burning out with one tire? aside from the v8 jokes, that's a lil embarassing

Because your v6 model does not have one. I was talking about the 8.8 your looking at buying, it does not need a posi as it already has one.

^ He's right, it says right there in the description.

8.8 rears are factory posi
