You need to get the #1 piston set to tdc ,Basically what you do is when you line up your timing marks you make sure that you are compressing #1 cylinder when you turn over the engine,also the rotor will be pointing to the #1 wire on your distributor cap .You have to un derstand that your camshaft turns 2 turns to 1 turn of the crank,so you possibly could be off 180 degs
