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.
