I had considered an IRS, but I was trying to keep this build fairly simple and inexpensive ( I know that's laughable). There aren't many Vipers or Vettes in the salvage yards around here. I might find a T-Bird or Mustang IRS. The engine I'm planning on using is a 383 stroker that I already have sitting in the shop.

Another factor is that I wasn't planning on pulling the body if I could get away with it. The link type solid axle setup could use the existing leaf spring mounts on the chassis and all I would need to add is the upper mount. It might not work out that way, though.

If I'm forced to pull the body, I will take another look at an IRS. I'm certainly not going to argue that it's not better for road holding.
