I know you guys like the Holly design or Demon, me, I'm lazy and like the simplicity of the Edelbrock AFB. What would be an example of the .95 peak efficiency with respect to equipment?

I have always used the following formula and rounded down.
80 to .95 x CID x rpm

The .80 to .95 is based on the efficiency of the engine. Use .80 for a stock motor and increase as you feel your motor approaches peak efficiency.
I would also recommend a double pumper and not vacuum secondary.

Wouldn't mechanical secondaries hurt him on the street? The opening rate of vacuum secondaries can be easily tweaked for strip use.
