Looking for any company that ever made a tri-power set up for the 348-409 engines besides GM's one and only cast iron piece.

Had someone claim on Faceworld that Edelbrock made a tri-power but I'm not aware of any company making tri-powers for the 348-409 family other than GM themselves. Anyone have a picture or maybe an old ad of an aftermarket tri-power intake made for these engines? Not sure why anyone would since the cast pieces are plentiful.

No aftermarket tri intakes that I'm aware of.

I've seen someone take an 881 and make it a tri-power but that is some major work and not an aftermarket piece for the masses either.

None I have ever heard of. If anyone ever did it would be Wiend or some other old company and they never would have done it in cast iron

You might check with Rob Walden he had a 60 Chevy at Columbus Super Chevy a few years back that had I believe Aluminum 3x2 intake on it
Not sure if he made or not

Well, if your good with a Tig welder you could always cut and stretch a SBC one to work, or maybe use a Mopar tri-power and adapt it. That's if your good, I know I'm not.

Pontiac made an aluminum tripower intake for their389SD program, can't remember if it was for 59 or 60, but they are few and far between, I personally don't remember seeing any aftermarket tripowers for the W, but there were lots of them for Pontiacs and Olds who also offered OEM tripowers for their engines so I wouldn't be surprised if it turns out that some were made for W's.

You know, I just got to thinking about this. What if someone were to take an Offy 2X4 intake and cut out the center of it and make a new tri-power top for it and weld it in there, just a thought. After all, the Offy intakes are like mini tunnel rams.

Anything is possible. I figure our 3d printed intakes will have an updated tri-power and might make one for the large ports too.

That would be cool, and make the new intake so it would accept Holley 2bbl's too.

That is a hand fabricated one-off intake made to fit the Holley carburetors that are on that engine.
