You can increase your mph and lower your et by increasing your rollout. Get a 15" front wheel and a larger diameter tire. Run the max air pressure on the sidewall. Stage very, very shallow. On the rear with a street tire run as much air pressure as you can and still hook. If you have drum brakes back the adjusters off a hair.
Good advice, but one error and an added note: Despite increasing the tire diameter a bit, going up on front tire pressure actually quickens RT's because it will "lift" the tire up in the staging beams and reduce the "flat footprint" that the beams actually see. So a taller tire will take longer to leave the beams and give more rollout, but less pressure will keep the tire in the beans longer. (i.e.: Measure across the tire 3" from the ground. Let most of the air out and measure again.)
The down side of increased rollout is that it slows reaction times. (As long as you stage in exactly the same spot.) So if you want slightly faster ETs, stage shallow with tall tires and moderate pressures. If you need to adjust RT's to be faster, use shorter tires, higher pressures and/or stage deeper (bump in).
As for the Action Plus, I'm pretty sure that internally it's the same as the Stealth. The carb mounting flange is just machined differently.
