Cam Gear Drive?
That nostalgia 392 hemi gear drive is a Milodon 13600(or what it was copied from).
If you can find me another CAT GD318N Ill give you $50 finders fee and pay the seller what he wants. Been looking for one forever and CAT doesnt make them anymore.
The Pete Jackson Dual idler takes a very tight fitting (you use a piece of newspaper to set the clearance!) and if set up in this manner, there is no perceptible backlash. They also tell you to inspect after break in and if the gears are blue, they are running to tight! I cant remember how you set the clearance though as it was my friends 351C-4V motor that had it on and it did not make much noise at all. I think one of the captive gears had a nested eccentric center (like an oil pump) that you could rotate and take up clearance then tighten down.
