engine, cam choice.

[anthonys 69]

hey, I'm trying to find the right grind cam for my dart 427 sbc. fuel injected and supercharged. it would be very helpful to me if you could list your engine, your compression ratio, your cam choice, then I would like if you could list idle quality and engine vacuum. and if your happy with your choice. even if your engine isn't the same size it would help put me in the ball park. I want the biggest cam I can get and still keep vacuum for power brakes and drivability.
machine shop recommend cam#1comp cam duration 288/315 lift .520/.540
summit recommend cam #2 comp cam duration 276/288 lift .502/.520 but summit does not take into account the engine size. any help would be greatly appreciated.
thanks
