Timing Gear Drive
Yesterday I did the basic install on my 392. Was gonna snap pics for you all but the batteries crapped out. I'll post some later this week maybe.
Mine came with no instructions, used the online version, which are so generalized that they are not real helpful. For instance, it says install the gear plate over the cam retainer. I don't know 318's so I don't know if the retainer setup is the same as 392. It didn't take long to see that it was not going to fit over the stock retainer plate, which is how I interpreted the instructions at first. On the 392 the gear plate replaces the retainer plate.
Mine has one hole to drill and tap. Instructions say to depth of 3/4". At about 5/8"+ it broke thru to the crankcase, kind of thru the sloping side of a reinforcement rim, so I raised drill rpms to avoid a broken bit. Tap went easy. Of course chips fell into the crankcase so the block had to be cleaned yet again.
Degreeing wil be a challenge as I'm using an old cam with no timing card. Oh, my crank gear does show the keyways as differently placed re' the teeth.
