Caddy motor questions

I'm getting ready to build a 390 Caddy. Any place I can get tech info beyond bore and stroke? Nothing i have found yet goes into any depth, and I am planning some modifications that require more info.

 

I can help with the standard compression ratio, crank journal sizes, torque specs cam timing, rod and main clearances, piston pin sizes and some carb settings...the stuff Chiltons' always has.

 

I have the normal specs Rocky, I need things like port volume, bearing width, compression height, head cc, cam specs, you know, more, more MORE!!!
