Is it possible the added CFM made the car go quicker?
My take is this, the largest carb that will CORRECTLY meter fuel on the intended car/engine/ RPM range will run the fastest ET. Not to take away from any carb rebuilder, they make changes to correct metering issues over the entire operating range of the carb. This will help on throttle stop cars and footbrake cars. On a wide open/transbrake type car, I think the advantage of a "Professional Built" carb over a stock, unmodified carb is diminished to less than a tenth with flow rates being equal and correct jetting for the app. The 9375 or 9377 Dominators (1050 or 1150) would work fine for your car if you take the time to get the jetting correct. If you have money burning a hole or don't want to set it up yourself, any of the above are fine, another is BLP carbs. Just remember, you still may have to change jets on anyones carbs to match your combo.
