My past experience has been solely related to SBC and BBC motors. I have had my LT1 car for quite a few years now but can honestly admit I am not that familiar with the engine design besides the fundamental basics of standard 8 cylinder pushrod cam design.

I was wondering if anyone had some good links or articles related to the specifics of an LT1 (reverse cooling, vacuum, optispark, etc...) that may provide an understanding of how the engine was designed to operate.

 

Here's a great acticle by Ray Bohcz explaining the Optispark that was originally published in Popular Hotrodding mag.
