They are paired. "Schultz intake." He made a manifold for individual throttlebodies. KMS throttlebodies, if I looked it up correctly.

These links show some "Howard" heads that have paired ports as you said. One picture in the 1st link shows "Howard" cast into the head. "Howard" is Howard Johansen of Howard Cams fame.

Scroll down for 2nd Howard head with what looks like Hilborn injection [forums.aaca.org]

Looks like a Wayne valve cover [jalopyjournal.com]

Bare head [bpeheads.com]



I'll bet Panic is right about the Howard heads having paired intake ports. So What head is shown in the original, non-paired intake, picture?

The distance between adjacent throttle bodies in your picture is the same all down the head.
So each pair of throttle bodies *1+2, etc.) have a "Y" shaped manifold to conform to the 2-2-2 intake ports?

Yes. Although, it’s all one manifold.

Looks like the nuts are already off the manifold studs. Pull the manifold and look for "Howard" between the #2 and #3 intake ports.

Don't need to. It can be seen with the manifold on.

Edit: Looking closer those are injectors.

What electronics are you going to use to control it?

Edit Deux: Is this the 302 you mentioned in your other post?
