Great advice, great references... exactly what I needed. Thank you. I also bought a couple books on turbos and I'll read up on them in the next couple days. I already have "maximum boost" and its a good intro, but lacks some "meat" that I crave.

I would absolutely love to run big boost on this big caddy, but unfortunately it has an entirely cast bottom end. The crank is nodular and I'm sure it would take it, but the stock rods are weak, as are the cast pistons. Forged pistons are available for a crazy price, but the hypereutectics that I would want are not available. Caddy guys have reported problems above 8 psi or 550-600 hp on a stock lower end, so I don't want to kill my reliability in the process.

Keep the opinions and tech coming, and thanks!
