School me on Stock Eliminator?

I like the engineering aspect of it, it's gotta be way more satisfying to make power with factory parts rather than just thumbing through a catalog and ordering stuff. I myself wouldn't be looking for ways to cheat but just how to extract power from stuff within the confines of strict limitations. In my mind, it's serious blueprinting leaving no detail to chance. There's no real secrets, just the search for perfection. Things like reducing friction, rotating mass and windage are all the enemies of an efficient engine, I guess those would all be major factors to address. Clearances would really come into play, careful balancing, quench area etc.

I'm really looking for 'prevailing thought' about how to make this stuff work, like how to take advantage of camshaft duration when limited by the stock lift specs. What design aspects of the cylinder head are taken into account? How do you come up with cam specs for a given combo?

Burning questions, all this stuff.
