Timing chain vs. gears

If thats for the LS type engine, its going to be a little cramped under the timing cover

I'm looking at putting the new dry sump pump on mine with the zo6 front cover and balancer--

One of the really neat things about the Donovan type gear drive is that you can just remove the front plate to change your cam timing or even change camshafts

It's an Aussie built unit made by a company called Diecrest engineering. They make a lot of the belt drive setups and export them to the US. I think they may be under someone elses name over there. They are just up the road from me and seem like nice people on the phone.

Here's a couple of pics of the setup:





It looks dead easy to change cam timing with the offset dowels. With a 2 piece cover or a cover with a removable window it would be easy to change without pulling the balancer. I'm thinking about machining up the stock front cover to have a removable panel.

This should work fine with the Z06 dry sump setup as it sits behind the oil pump in the standard timing chain position.

Price is not to bad either @ around $400 Aussie compared to $180 Aussie for a Rollmaster timing set.

Cheers
