    TBI adaptor 3d model

    Does anyone have a model of an adaptor to go from GM TBI to square bore? I'd rather not have to draw it from scratch. Anything would help.. Thanks

    Why not just buy one. They are really not very expensive.
    Free Shipping - Holley Throttle Body to Carbureted Manifold Adapters with qualifying orders of $109. Shop Throttle Body Adapters, Carbureted Manifold at Summit Racing.


    I thought about making one, but by the time I bought a piece of aluminum or steel, and then cut/drilled everything out, it was worth the $65 just to save a ton of time and frustration. No machine shop could make one for cheaper than that either.

      Thanks, but I did buy one off ebay, but the damn thing is so ugly. Been on the jeep for a few years. Going to make something that looks better.

          Holy cats! That thing is $65?!? I bought mine on ebay for like $15 shipped. Mine was ugly, too. Nothing a sandblaster and some satin black paint couldn't fix though.

          If I had to do it again, I would order one from men in black. He makes nice stuff. Could you make one in Phenolic?

            Yes I can make it out of Phenolic, Here's the measurements I found.
            also found some 1/2" black Phenolic online. Its all drawn up in my CNC program.
            Just need to order the material.
