The 409 hi perf engine had 2x4bbls.   The hi perf 348 had 3x2bbls.

The 348/3x2bbl looks really bitchin' in a street rod.

Just about everything GM has made was available  with 2x4bbls at one time 
or another, including Cadillac.

By the way, that hi perf 409 was a real kickass engine as long as you 
didn't try to rev it to 8000 rpm.    It's also the forerunner of the modern 
bigblock Chevy engine and has a very similar bottom end.    In fact, if you 
turn a 454 crank's mains 1/8" it drops into a 409 block and gives you 
almost 500 ci. (rods need to be addressed) since the 409 is a big bore 
engine with a relatively short stroke.   That would make for a real stump 
puller of an engine for street use.
