What transmission Manual or automatic?
If automatic, what stall speed converter?

Is the intake a performer RPM or the smaller performer?

The deal with using a large carb, is it has less restriction and will make more power a WOT, but when driving on the street at 30 MPH, you will still be in the transition circuit, not the main metering circuit. This is not really a big deal if you know how to tune the transition circuit, but it is not something most people do.

A smaller carb will get into the main metering circuit sooner (more throttle angle at the same speed) and usually it is just tuned with a jet change.

What about the FiTech TBI EFI? Not that much more expensive and you don't have to pay extra for all the carb tuning parts (jets, bleeds, restrictions, power valves, accelerator pump cams, and nozzles, ect.) and gaskets.
