Name that intake?

Pretty sure that's a Hilborn individual-runner mechanical injection manifold without the velocity stacks installed.

I agree. Perhaps not the best choice from a performance standpoint but pretty dang cool!

Engine Masters played with a set and the dyno sheets were weird. The power curve was like a sign wave throughout the RPM range, and changing stack lengths just moved the peaks and troughs. They're also pretty weird to tune. The jets in them are for the fuel return. So if you want to lean it out, you put a larger jet in (sends more fuel back to the tank) and if you want to richen it, you put in a smaller jet. Kind of counterintuitive. The Pete Jackson systems are reportedly the better system but rarer. For example, Hilborn put the throttle blades down at the base, while the Pete Jackson system located the throttle blades about 12" higher. When you got an engine with Hilborn stacks warm, the manifold base would grow and you'd get massive leaks past the throttle bodies and you couldn't get them to idle right.

Enderle also made injection manifolds. Everyone always forgets them.
In reply to Appleseed :
So did Crower
And Kinsler
The Kinsler Cross Rams look sick, although it seems like they'd be picking up hot air rising from the exhaust manifold.
The Autolite inline 4-barrels are also rad. Neat idea on paper, with better fuel distribution (venturi bore spacing was 4.38", right about the same as a SBF, so you had a venturi feeding 2 cylinders with a near straight shot). As I recall, they worked okay in a race application, where you could keep the engine on a boil at all times, but were miserable at low-RPM and cold-start, since they were basically four massive primaries. They made a single carb intake for Boss 302s and, supposedly, an ultra-rare dual-carb cross-ram manifold for Boss 429s. Personally, I think one on top of an 8-71 blower would be the hot ticket.
