Ok team... I have to select a 4bbl carb for my 292.

I have a number of vintage takeoff holley/motorcraft/autolite units that have been in storage for 30+ years to choose from. My initial plan is to rebuild one and keep as many vintage parts as possible on my build.

I think a 600cfm would be sufficient based on my limited knowledge in volumetric efficiency etc...

Any opinions as to jet size for the initial startup and break in? Or strong opinions of a better carb option?
