Crank up, cam down so they line up. If you know some one with a degree wheel and dial indicator kit make use of it you would be amazed at how many are off mark a degree or 2 on the factory marks.

with the crank at 12 oclock and the cam at 6 oclock you will be on number 6 compression stroke...turn the crank one revolution and the crank will be at 12 and so will the cam...now your on the #1 compression stroke....so ...install crank 12 and cam 6...then rotate crank 360 degrres for the distributor install
