I'm going to put a solid rear end out back in my GN powered '87 RX-7 over winter and can find the Ford 8.8" rear in abundance but the Mopar 8 3/4" setup is a little tougher to find. I plan to run 9's and I'm doing this not only for reliability but to meet NHRA rules. I am having my engine built with all the SFI spec parts currently.
Does anyone know what each of them weigh? I know a 9" is a portly beast and weight is what I'm trying to shave off of my car so that isn't an option plus they are too costly. My car should weigh around 2600-2700lbs.... closer to 2600lbs without driver.
Engine at full tilt should make a little over 700hp and obviously more torque with our hairdryer V6 monsters. I plan on 31 spline axles and an Eaton posi with 3:07 gearing. Most likely 26x10.5" tire or a 27" tall tire. Any taller I believe requires tubbing in my RX-7.

2nd question:
I will be driving this on the street 70% of the time and want to do a ladder bar setup for simplicity.... but wouldn't a 4 link allow me to raise/lower the rear end and allow for a slightly taller tire and more tuning adjustments? Can a ladder bar setup do this?
Which would be better on the street and not squeak like crazy? Any recommended manufacturers to go with?
My goal is a few passes running 9.50's@145mph on full tilt..... but mainly 22-24psi on 20* timing running some low 10's with a T-70BB and 100 octane unleaded or 91/alchy. My mods are in my sig.
