Cap: Since you said this thread is intended for learning I'll add one more thing for the sake of learning. Again, this is from my view point as a racer that drives my car on the street. I need my car to tread that thin line of being street-able, and a winning bracket car.
For a race car, or a serious street strip car, you can't go by the cfm calculators. Your perfomance oriented cars will almost always go quicker (make more power) with a bigger carb than suggested by a cfm calculator (to a point, without going too big). This is largely due to the fact that many race engines achieve greater than 100% volumetric efficiency, and the generic cfm calculators for carbs don't take that into account. There are MANY examples of guys running their 4150 style carb (like a 750dp), swapping to a 4500 style (like a 1050 dominator) and picking up 2-4 tenths in the 1/4 mile (sometimes more)....So no, its not over carbed if the person driving the car is someone like me, a racer that drives his car on the street who wants consistency/max power/ and the car to be street-able (in that order).
