Back in the olde days, we had things on vehicles called carbeuretors...
A 2-v carb was a 2-barrel, a 4-v was a 4-barrel.
Just to be technically correct, the "V" in 2v or 4v stood for Venturi, although most of us Americans called them barrels.
And BTW, I have a single SU carburettor (as the Brits spell it) on my Mini and although it doesn't lope at idle, some people still think its cool!
And if I ever get the Suburban done, then I can get the Mini engine done!
