Holley’s carburetor selection guide tackles the argument every muscle car owner has had at least once — what size carb actually belongs on this engine — with real CFM math instead of bigger-is-better folklore. The video breaks down why oversizing kills drivability, how vacuum and mechanical secondaries serve completely different kinds of builds, and where street and race carburetors part ways. It is aimed squarely at classic muscle cars and daily-driven builds. Watch the full guide before your next trip to the parts counter.
