Since you're looking for options, I would suggest contacting Mark at
SC&C and borrowing some of his suspension expertise.
He does pro-touring suspension consults and has probably forgotten more about the subject matter than I will ever know.
Also, I'll shamelessly pimp his book "How to Make Your Muscle Car Handle", which is due to come out later this summer/fall. You can pre-buy it on Amazon.com
here if you're interested. If it's half as informative as the man himself is, then it'll be the best $16.47 I've ever spent.
