Thanks for all of the help everyone, there is a lot for me to think about and hopeful build on, I really appreciate it.

To answer a few of the other questions, it has a full 2.5-inch exhaust.

It picked up from 13.6's to 13.4-.5 when I dropped the shift point from about 5,250 to 5,000.

As suggested, I will play with jetting and timing and so forth (including making sure it's getting enough fuel), and I may try my 850 cfm carb again. Once I think it's running as hard as it can from 60-feet out to the end, I will look into launching a little harder and trying to drop the 60-foot times into the 1.7's.

I try and fly the classic Mopar colors the best that I can, a lot times I have the only traditional muscle car in the street tire class in a sea of modern Mopar stuff, Mustangs, Camaros, BMWs, whatevers. They're fast but they're boring.
