Did a little Googleing and found this.
Hilborn Injection
As fuel injection goes, this is nostalgic. It isn't very streetable, it needs constant tuning, but radical looking with 6" chrome stacks. These setups only know one mode; wide open. They will idle, but anything between idle and wide open is terrible. If you want this type of look then consider Webers or Delortos.
Heres a Tech thread about them. CLICK HERE

Hilborn injection is a 'Constant Flow' system. All nozzles are flowing all of the time.
Exactly. Fuel flow is controlled by the pump, whuch must be carefully calibrated to maztch the engine, and also by a "barrel valve" which is connected to the throttle linkage. That are very cool looking systems. They are not WOT or idle only, they (or similar setups) are used even today on sprint cars and world of outlaw stuff, these machines need good response and midrange power sliding thru the corners.

They are also available "electrified" these days. I saw one on a street rod at a cruise last year. VERY cool. 8 giant stacks sticking up, no hood of course. The EFI conversion burried the injectors inboard and low, in the valley. The original "fuel spider" was still there, but was used for nitrous. It was a very clean and well hidden installation, the motor ran very well, and has good street manners.
