I've been looking for a throttle body for a standard American 4-barrel carb manifold. Here is what I've found so far. Please add to the list.

Some others - haven't tried any of them:

I forget where I got this link from and I have never done business with them.

Interesting. Would the last two with the built in fuel rails be considered TBI (since entire manifold is wet) or port (since they butterflies are dry)? or something in between?

Mike

Something in between. I haven't heard good things about fuel distribution with injectors below the butterflies.

I presume you want a billet piece for show - otherwise you can use anything that flows air and can have a TPS fitted to it. A common one is the use of a 4-barrel carb body and adding a TPS. Eliot Mansfield covered his adaptation some time ago on his site. Also, this page shows how he did the TPS. Of course, he did a lot of mod and fab to it, and you don't really need to do anything to make it work except remove the fuel line and add the TPS.

No, just want a "top breather" with a massive 1960's style air cleaner sitting on top of the engine. The throttle body will be pretty well hidden.

Of the units described in this thread I'm leaning towards the BBK unit (due to price and no import duties).
