has anyone ever tried this, or heard of someone putting three webber 40 or 44 IDFs on a flat six?
you would have to build your own manifold, but I'm sure there are many here who could do that
tig weld aluminum would be ideal
gas weld or braze steel would work too
solder one out of copper? you may have a galvanic problem it the copper touches anything steel
carb heat may be needed in colder climates, but probably not in So Cal
if your on a really tight budget or don't want to spend a ton of money for a mini science project, you could try three of those EMPI knockoffs
