Let me put in a plug for the technology I am using - the FAST EZ-EFI throttle body fuel injection. It bolts to the standard Holly square bore bolt pattern on the manifold, flows 1000 cfm, and solves most of the compromises that have to be considered between performance, throttle response, and streetability. Not to mention that tuning can be done with the push of a few buttons on the hand held pendant.
Yea, it is 4x the cost of a carb, doesn't work as well with big, lumpy cams, and it somewhat technical to install, but when you get it right, it is fantastic to have instant throttle response and better fuel mileage.
