Big Block Gear Drive On A Slant?

Ok then, so lets just say for the sake of argument, I decide to convert to a fixed idler. How much clearance do you think will be good between the cam gear and idler and the crank gear and idler? In other words, WHERE would you mount the idler?
I wouldn't try and ruin your thread but you know yellow rose just called me out twice in this thread just now and I would really like him to answer to his thread (quote) "it will happen!?" there's plenty of conversation there and everybody is wondering where he's at and why he's out giving all this technical advice without owning up to his shortcomings....
Honestly I'm quite enjoying the conversation here about the Gear Drive. I talk to my own machine shop about that when I first had my motor done and was discouraged and told I could spend my money in better places. Anyways I'm enjoying just reading the conversation...
