I have a 6 cyl manual 64 1/2 Mustang and am looking for a V8. In ads I see 4BBL and 2BBL. What does that mean? Which is better and why? Thanks. npomerleau@comcast.net

It's the type of carburetor, 2bbl is gas saving for a V-8, the 4bbl will give you more hp but less fuel saving. Car companies used carburetor's before fuel injection became the norm.

The 4bbl with give you the most performance if that is what you want, though normally the engine would be a little more expensive to purchase than the 2bbl. As Stacy has posted ,it is the carb difference but this also means a different intake manifold and sometimes camshaft profile and on certain engines valve size's are different too.
