roll 4BBL or 2BBL?

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

Re: 4BBL or 2BBL?

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.

My first car was a 67 Mustang Coupe, 2nd one was a 67 Cougar XR-7, 3rd one was a 66 Mustang Coupe. Why did I get rid of these cars for ? I know why, because I'm stupid, stupid, stupid.

My next Ford.....

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.
