Hey I just finished rebuilding the head on my SOHC.

The easiest way to tell if the cam gear is posistioned for correct timing is to look at the camshaft first. Looking at the front of the shaft, (where the cam gear used to be,) you will find a little pin that sticks out of the end of the shaft (just above the hole where the camshaft retain bolt was. This little pin is called the knock pin. Make sure that this pin is set in the. twelve o clock position. Now looking at the cam gear, look for the mounting hole in the center of the gear. There will be a rectangular notch. The notch itself will be aligned with the knock pin, and the notch should be at the top of the mounting hole on the cam gear when you mount it on the shaft. Also look on the outside perimeter of the gear for a small circular punchmark. This should be to the right of the mounting hole on the gear, and should be at a three o clock position. Just remember, that there are a few components that have to be properly aligned when you are correcting the timing on the SOHC. The distributor shaft, the crank gear, the oil pump drive gear, cam gear, and timing chain chain itself all have to be in synchronization in order for you timing to be correct. I hope this helps. I've can get pics too. All I have to do is tear apart my motor for some handy shots. (No sarcasim) Always willing to put in a few more wrench hours to help a fellow 240 owner.
