Great advice guys...Thanks!
I guess having great power AND great traction is a nice problem to have...
Jim that's pretty much Exactly the approach I was going to take.
Mr P, if I soften the shock I'm worried about the softer compression (they're not double adjustable to my knowledge) lowering the CG more...Right now it just dips slightly, plants the tire and goes, I'm just thinking with the Rocky anything I can do to prevent raising the CG at all(LOL) could and should be avoided!
The back seems to be doing it's thing perfectly, if I can reduce the rate of rise in the front without unloading the contact patch that would be the best of both worlds.

Look how short the rear overhang is, Standing on the bumper would put me at about 83 degrees to the ground!
Standing her up is the easy part, setting her back down with a short wheelbase and a high stall/light switch converter may a bit trickier.

The first pic shows how my brother's Gremlin left the line on every pass last year during Hot Rod Drag Week. 9.30's mostly, until the shootout, when he added a second plate system, and dropped to 9.0's. He eventually melted some pistons on an 8.95.
This year, new pistons lowered the compression, swapped the SRs for a set of -1s and backed the cam up four degrees. The 440 responded with a 9.08 on one system, but he was concerned about a 100 foot wheelie on that run.
The second pic was his first run trying to add the second plate. He let off the nitrous early, and tried to drive through it, but when the rear tires left the pavement, and the engine hit the rev limiter, he lifted briefly. Gasoline hit the windshield, when he stabbed it again as the car started down, the engine simply bogged and was unresponsive. It's going to need a new rack, and the front rails straightened...but, he has the hero shot to show everyone!!
Caution, Streetwize, is the better part of Valor!!

Billy, that Gremlin is insane! Good advice and I'm a big fan of Clint Eastwood's "a man's got to know his limitations'
After some trial and error, I've made some bumpers that will limit the rise from 5.5" ( way too much for the short wheelbase) to about 2" before contact and 2 1/2" before it starts to lift the unsprung weight. That should still give me enough unsprung hit to plant the tires and also limit the trajectory of the wheel stand to something far more controllable, it should at least give me time to hit the next gear before the Rocky gets to the 'Event Horizon', lol.
I watched the video a hundred times trying to figure out where the balance point is, can't wait to try it out again, thanks for all the constructive advice!

Go green, Respect your opinion but as you can see in the video the car typically runs straight as a rail. http://youtu.be/BB49eJu-YEUIt's been running consistent low 11's but the 60' has been slow high 1.6/low 1.7 so if I get the car off the line in a typical high 1.4/low 1.5 as it should with the new converter, the car should run mid high 10's which is all I really want out of it. It's got a 6 point cage and the chassis is rock solid and the steering is slow so it's really easy to keep straight. I feel more safe in this car than most of the cars I line up next to, it's very solid, nothing flimsy about it at all.
