What is a "four-barrel" for an older car?

[InlineFive]

Someone mentioned that they had an old Oldsmobile with a four-barrel that had about 300HP. And I was left wondering what a four-barrel was. I think it may be a certain type of intake manifold but I'm not 100%.

What does it do?

When someone says they have a four barrel, they are refering to thier carburetor, which deals directly with the intake manifold, so you werent too far off

yep.

4 barrel carb.

good stuff. Big FAT barrels. 4 of them.

What does it do? More air, more fuel.

Me too. I rebuilt the carb on my first car ('76 Olds Cutlass w/350 Rocket).

4 barrel

As opposed to a 2 barrel

More "barrels" = better metering per cylinder, allowing a better overall tune. Not to mention more fuel and air, therefor more power.

That's a dual quad. Not a four barrel. It'd be a four barrel if you had one carb and split it.

Edit:
old school cross ram FTW (until you had to change the spark plugs)

a 4 barrel carburator....
it gives gas/air to the engine.. you know those crazy devices before fuel injection was invented?

Brings back memories of the '60's muscle cars -

Like when '4-on-the-floor' meant a stick shift transmission with the gear shifter coming out ot the floor tower -

and not getting lucky on a double date.
