Art,
What you might need is a step up in your electrical system.
There are a few systems available. I would give Pat Collins a call @

I got a well known Comp team hooked up with him and he helped their program. I can tell you first hand that his Max Power system made more power on a dyno I am associated with than just a good 12 volt battery with a charger attached. That was with a MSD 7 system and the appropriate coil. Listen to him when he talks about coils.
Also, I agree with Jim about the correct sizing of the fuel system. The bigger is better way is similar to what I call the "Shotgun Way" Throw enough lead at anything and you will eventually hit it. You need big enough, but too big has some problems like air in the system and heat soak. Plus a few other issues.
