Yes, as mentioned, the Scott won races back when, but seen any in the winner's circle in the past forty years? No, Scott's are not really streetable. Now, here come all those who swear they are driving stack injectors in freeway rush hour traffic. Yes, it can be done by very patient, very savvy builders who live in warm, mild, low altitude, but kids, don't try this at home. Maybe, think about the OEM systems which made constant-flow injectors actually work. The one thing they all have in common is they DON'T have stacks. The '57-65 Chevy Rochester had a common plenum and butterfly, as did the '80s Bosch systems. When there is the ability to measure all the air and use that to adjust volume and mixture, constant flow works on the street. But then, this thread is all about the looks and secondarily the horsepower the individual /isolated runner stacks make. So IR = not streetable. Think having to build a separate starting priming system or alternately, squirting raw gas down the stacks, a la Tommy Ivo on his nailhead T-bucket roadster. There is one nice side benefit of IR stacks; the isolated runner does reduce the effect of long overlap camshafts. Once properly tuned, the IR will idle and pull from low RPM much better than today's common single plane intake. jack vines

Oh God, you've just brought back my nightmares. Where's the Scotch? The guts of those things was basically an air meter that varied fuel pressure to the injectors (measured against a reference pressure that was controlled by engine temperature and, later, oxygen-sensor feedback) based on airflow. The number of machining steps involved in the production of the valve block (the 'fuel distributor') boggled the mind. Very German. Also ugly as hell from an appearance standpoint. And the air meter attached to the fuel distributor was, in many applications, a giant cork in the airflow.
Chris, I just saw this H.A.M.B. site on Injectors. Is yours a 3" Crower like ours? When I saw yours last summer on your Altered Wheeelbase FX Comet I thought it was a BBC Hilborn.... Magoo
Bodies are 1960's Tecalemit Jackson (English, sold in this country by Holman Moody) 40mm, originally cast in pairs to dimensionally replace Weber carburetors. They were acquired from Rich, sawed apart, nozzles replaced with Kinsler and the idle air circuits plugged. Conventional pump, barrel valve and by passes. Thanks to Rich, I'm having fun also.
Here is mine in a 40 sedan delivery. The unit is an Inglese with a FAST operating system. Works fantastic.
I just picked up a Hilborn unit on Craigs List for $250! I need stacks and how in the hell do I run this on the street. I am now doing my homework, any advice is welcome. Thanks, Bill
