My every day driver is a 190 with a small block Ford (now 342") and a 5 speed and was built at first in 1995 with updates of sorts ever since.

The rear in mine I feared would be too fragile and I wanted a ltd slip diff with better gearing. I've installed a diff from a 92 ZR1 Corvette ( same as a Viper) with a 3.42 gear ratio. The axles are custom Spicer units as is the one piece driveshaft. All is balanced great and never a problem so far with reliability. After doing more searching a 8.8 Ford diff from a late Lincoln MkVIII, Thunderbird or Cougar all with an independent rear will also fit.
Superformance uses this in their Cobra kits with big blocks!!

A simple front sway bar with beef is a 124 - 400E or 500E as they have a projection in the sump area. Just cut off 1 1/2" from each end and install. The 400E is 1.055" and the 500E is 1.125"D.
I'm now in the process of making an additional 3/4" bar that is adjustable for the rear.

To eliminate all my steering constraints, I've put in rack and pinion
and shortened the arms for better response and feel.

For suspension, Eibach 2.6 springs and Bilstein sport shox handle it well as it weighs just 2980...54% frt/ 46% rear.

Sounds as if you have a handle on your project and should have humps of torque! Good luck.
