I've run one of those before. One of the things I don't like about it is that one of your basic adjustments requires the removal of the top of the carburetor. Another issue is that Summit's quality control on those isn't what it should be, I had to go buy a replacement fitting for one of the included parts that came with it, and break out a thread tap for another the day I bought it.

I've owned, but never actually installed and ran a Street Demon, I bought a remanufactured one from Jegs when they had it on sale for $200 or so and the EFI system was giving me fits last time, but shelved it when that IAC from the salvage yard fixed the issue. When I really needed money last year, I sold it for what I had in it because they are now $320. I've run the older version of the Edelbrock Thunder AVS before, and found it to be almost as good as modern fuel injection when it came to ease-of-use. It was 100% on-the-spot for everything but idle speed out-of-the-box, 18" of vacuum at idle, and a quarter-turn away from idling at 800 where I wanted it, and I never touched a screw on it again, but my dumb ass wanted EFI.

It wouldn't even be a question, but I'm completely impressed with the design of the Street Demon, especially the need for zero parts or disassembly to change anything other than jet sizes. The Thunder AVS needs metering rods for the secondaries, the Street Demon has a set screw. The availability of one with a phenolic body to help prevent vapor lock on those 110-degree Texas summer days for the same price as aluminum is attractive as well.

I've had a load of carburetors over the years, even though I'm relatively young, I grew up with the things because I was poor white trash and that's what we could afford, old boxes with carburetors. So I learned how to work on them at a young age, then learned what I'd been taught incorrectly by my old man when I got a little older, and eventually even worked on them for a living at my first job as an automotive technician.

I'm even one of the few people I know that actually likes Rochester Quadrajets (an almost universally hated and misunderstood carburetor that has/had it's fans, including myself and Carroll Shelby) and understands them.

I'd still rather have EFI, just not this EFI, and I can't afford $800+ for an MS system right now, nor do I want the car to go through the downtime of troubleshooting a bunch of used parts cobbled together.

If I was willing to let the car sit again, I've dreamed up this crazy system that would look incredible. I'd mount a pair of these:



Onto one of these:



Using an adapter plate I dreamed up. Throw some 24lb injectors in it, switch one of the throttle bodies over to a Ford TPS, ditch the TPS altogether on the other, remove the IAC from both throttle bodies and run a Ford IAC on the bottom of this:


(which would draw air through the air cleaner, and pass it through a "T" to both throttle bodies when I was done with it)

And then either run it with a boneyard Ford EEC-IV (if I can find the one I need, and then get it dyno-tuned), or run a Megasquirt or something like it.

Then I'd have sequential injection that would look for all the world like a dual-quad carburetor setup.

Almost everything to make it happen is cheap and readiliy available used. The throttle bodies are mid-90s Dodge truck parts. The intake manifold is a mid-90s Ford F150 piece, the distributor to make it work would likewise come from a non-roller 5.0 in an F150, the injectors would come from a 460-powered mid-90s F250 or F350...

Yeah... my mind is broken, it happened years ago.

No, even after figuring it all out, I'm not going to do it. It'd be cheaper to go with a carburetor and the car would be down for all of a couple of hours.
