Biggest Cam in a 360?

Every step of cam level in degrees is gonna lose vacuum over stock and a race cam is gonna be in single digits. Whats the spec's of the engine, compression, cam, intake, headers, gears, stall speed, carb and what kind of car. I'd go with a comp cams thumper series or similar cam from another company, there design to give give a race sound within a more street spec'd engine.
