The first step to shorter braking distances is good tires. If your car is getting into the ABS at full brake pressure with the stock binders, then you will need to upgrade the rubber before anything else.
To fully optimize braking with the BBC, you will need to determine which end of the car is locking up first under the brakes. Sometimes an outside view during a replay will help. Ideally, you want the front tires to lock up just right before the rear ones do.
