I'd agree completely with a converter and gears. I have a B&M 2000 and 3.73's, and it launches GREAT! The only problem is that now that I have an E303 camshaft, there's a slight bog until it gets to around 3000RPM. Having said that, I shoulda went with a higher stall converter. If you've changed cams, you have to match your converter to your cam. PI's are the best, and remember that you get what you pay for, especially with converters. Be sure and install a large oil cooler if you're going this route, because the higher stall WILL generate more heat, the number one enemy of automatic transmissions. You may also want to consider some better control arms for the rear end. This will help your launch considerably better.
If you don't want to go with a transbrake, here's what I do: Mash your left foot into the brake, and then bring the engine up to your stall speed, if you can. It should be brought up to the point just before the rear wheels start to spin. Then when you're ready to go, immediately let off the brake and ease into the gas. If you completely mash the gas, you'll start to spin the tires, and that's gonna KILL your ET. Trust me, been there, done that.
