Holley 500cfm 2bbl for a...a....ford....

Sounds like it may be more than what Im looking for. It will be going on a stock daily driver 390 that as soon as it warms up around here I will be putting a 4bbl on. Im just looking for a stock 500 that may need a rebuild, cheap.

then there is the ford 2bbl base size. i don't want to have to get an adapter for a carb that Im just going to take off in a few months.
