There are two setting plates on the chain, one aligns with a notch on the crank gear with the gear in a particular position, the other aligns with a mark on the cam gear with the gear in a particular position. This particular position happens to be when the engine is at TDC #4. When these setting marks are all aligned the crank and cam are synchronized properly. I don't know how to synchronize the crank and cam without using these setting marks, so IMO the best thing is to put the engine to #4 TDC and then install the chain. It's not that hard, you need to set three things, the crank, the cam & the distributor. The pictures in the link show you what it should look like as you set each. Since you have the front cover off I assume you have the oil pan dropped and the head off, if not report back quickly, there are some things that must be done differently with either the head or the oil pan in place than if they are removed. Basically you are going to rotate the crank and cam to #4 TDC independently of each other to allow correct installation of the chain, then the correct installation of the oil pump will also install the distributor. DO NOT ROTATE ANYTHING IF THE HEAD IS STILL ATTACHED TO THE BLOCK, THE PISTONS WILL CONTACT THE VALVES. Report back.
