un-injected V-6s

[JHertzman@domain.elided]

In AD7-665 Eric writes "I never knew the V-6 used anything but 
fuel-injection. As a carb'd model did it use down-draft units sitting between 
the V? Did Alfa ever set the engine up this way and if they did is there a 
part number for the manifold? (I'm having visions of 'muscle-car' style 
protrusions through that hole in my GTV6's hood...perhaps some chromed 
down-pipes.)

"Just kidding about conversion for my GTV6! But having a spare engine and 
some ideas for possible projects, I would like to know."

The V6 was developed a loooong time before it saw the production line as a 
carbed engine in the Alfa 6 sedan in 1979. It had downdraft Dellortos with 
one venturi per cylinder, but swapping manifolds is not enough; the heads are 
different too. If Eric REALLY wants to know, the person with the deepest 
brain in the USA on these matters is Hans Milo of Smyrna, GA. Hans has an 
"ordinary" carbed V6 very neatly (and tightly) wedged into a '73 GTV, and 
also has a carbed three liter GTV-6 with an astronomical compression ratio 
running on aviation gas. I wouldn't try this at home.

On a different tangent, I have twice seen photos in British magazines of 
injected GTV-6 engine-bays with two plenums, one over the left head feeding 
the right cylinders and another over the right head feeding the left 
cylinders. In the context these were not shown as something different, just 
"This is what a GTV-6 engine looks like." I am curious about 
when/where/why/how, but it also suggests a way in which six single side-draft 
carbs could be used, with substantial ram-pipe effect, on a GTV6 if one were 
sufficiently ape.
