Heads or Rear end??

I'm a bolt-on only car and can't make traction for ****.. Don't want DR's since my Z is my Daily Driver. List of planned upgrades in order goes Built tranny > Rear end > Heads/Cam or Spray.
Granted, it will take a long while before I can get through that list, but I don't have the kind of cash to bust a 10 bolt at a random time then get it back on the road in a timely manner..
It's the same in the Jeep world; you're better off building for strength and then for performance.

i have personally blown up 1 set of richmond 3:73's and 1 set of motive 3:73's and 2 auburn pro series differentials...ON 315/35/17 summitomos...please for the love of god atleast get a 12 bolt moser/strange/ an SD60 if you can afford it and wait 5 weeks for them to build it..that way whatever else you do, however much your plans for the car change the rear end wont leave you hangin...
the gears were while the car was bone stock...the diffs were after i did headers and TB....

Yeah, I have the same mentality.
Get the heads first, and immediately start saving for the rear.
The stocker could last longer than you think, and for all that time you could be enjoying the extra power from the new heads.
Either that or keep saving, and just do the whole thing all at once.
Just my .02.

Just my opinion. I would stay away from the 8.8. They are good rears, but almost impossible to get the torque arm mount right. Do heavy research either way. I considered a 8.8 before I bought my current rear (12bolt) and heard great stories about 8.8s from years ago. After contacting some of the guys that were running 8.8s 3-5 years ago to see how they were holding up they all said the same thing. The torque arm mount is hard to get right, and had given up the fight.
Shop around, you might be able to find a 12 bolt cheaper than you think. I paid $1600 for mine, and it came with a custom 3.5" driveshaft. I sold my factory rear and driveshaft for $375. So I was only out $1225.

I bought my Moser 12 bolt used, 1600 as well i went out and bought all new bearings for it. When you go to auto zone, napa, etc,, and ask for Moser parts,,they look at ya funny,, but then i discovered that all the parts i needed to buy for my Moser 12 bolt are Ford 8.8 parts. (bearings) My BMR TA bolts up fine, but it is hard to get a 19mm tool up there...

The old cars came with th350/400s, larger diameter r&p gears, cheaper to build $-hp. The only downside is that a carbed sbc or bbc with a th400 or a glide and a 4.11 gear will not be anywhere near the dd the 4th gen cars are.

i would say to do the rear end first, because you dont wana start making power and not be able to use it... im building my street car backwards in the since im making sure I’ve got a good tranny, a good rear, and a good chassis... then start messing with the motor to make it faster...

Did you have to get bigger injectors and a new fuel pump for 440rwhp?!? I may need one of those soon...
