Ahh, timing sweep is a very cool thing. The easiest way to do it is with a Consult. The Consult allows you to advance or decrease the timing through its interface, without manually moving the distributor.
You start by manually setting the timing at a high number like 22*, and run the car on the dyno. For the next run, pull the timing back to 20*, next run 18* etc. Once the power starts to fall off, raise the timing by 1* to find the optimal point. 19* was optimal on my car with stock cams and 89 octane gas.
