If you use a timing light. you will need a degree indicator that mounts to the front of the engine and sits over the crank pulley. NuRex sells them. The timing can be adjusted in small increments if you have it set manually to a close degree. Full retard should be about -5 degrees. Full advance should be about 22-24 degrees. NEVER 40 degrees as someone suggested. You would burn the engine up and melt the exhaust. My shop times every car to those specs and they all run and start great.
