    Would a Dial-A-Jet be helpful, in conjunction with the shut-off?

    squirrel -

    I know a couple of people that have run Port Injection on the street in the past. Small and big Chevy and a Ford.
    A fair amount of work and bad gas mileage is the common theme. Takes a lot of work on the barrel valve to make it truly street-able.

    I know a guy that's friends with the owner of the port injected, silver Chevy II. I may be able to contact him if that's still your plan.

    I'm not planning on running mechanical injection on the street.

    Might be a good idea to design swivel nuts with tethers, at the end of the day your tired and in a rush to switch to carbs. Bolt it all up and come up short 1 carb stud nut :oops:
    Spent an hour or two looking for it at the track with no success :mad:, push the car on a trailer and spend next day with intake manifold removed looking for it through plug holes using a bore scope, turn it over by hand :eek:
    (recheck with bore scope) then turn over with starter :eek:, lots of pucker factor when you finally start it.
    You never do find it o_O

    I expect that gluing the screen gasket to the top of the blower would be part of the plan!

  7. Here is the two port setup on our dragster... Four Bolts on the blower and a single fuel line to barrel valve.

    May not have the "look"..

    ^^^^^ Jim, clarify port for me. I understood early in this post you didn't want it. In your defense, I took it to be at the base of the intake runner just before the head/heads. That's why I posted that style injection on the FED.

    Cool. 61cad's set up sure would be a lot easier.

    that's pretty much what I have in mind, but using a hat instead of a vertical port setup.

    A safety consideration... When you are driving on the street, you’d store the injector setup in the car somewhere. You can’t empty it of fuel completely. Somehow you have to make sure the storage spot is ventilated so you’re not going to be inhaling gas fumes all the time, or worse yet it becomes a fire hazard.

  18. Two pots were early 60s injectors. It would look out of place on a a/fx car. By 65 they were obsolete. The hilborn horizontal and upright four ports along with the enderle bug catcher were the preferred choices.

    I bet if I dug my old 1966/7 Hot Rod Magazines out of the back of the garage I would find grainy pictures which look an awful lot like Jim's 'Cuda

  20. With enough playing around you can make a mechanical Injected car run just as smooth down the highway as a carberated car. My coupe runs really good on the street. I never even prime it to start it. I dont use the fuel shutoff to lean it out going down the road. I would drive that car anywhere. I have thought about putting a adjust a jet on it because I have went to car shows early in the morning when its cool then later in the afternoon when i leave and its hot out it runs rich. With the adjust a jet you can lean it out or richen it up on the fly. I run a hilborn 4 port on it.

    Out of curiosity what kind of mileage do you get? Jim has a fair amount of driving from strip to strip during Drag Week.

    I was told that a screen in a 6-71 cost 50 hp, never ran one on any race engine.

    I wouldn't think that a screen would have to be very fine mesh to stop the ingestion of tools and hardware.

    You already have a trailer - or did you sell it?

    I read a magazine article long ago, an interview with one of the famous mag builders. He said he'd been hearing for years that the resistance to rotation of a mag would cost 50 horsepower at high RPM. Said he didn't think it was quite that hard to turn them since he'd had thousands of them on his test bench over the past 20 something years and it was powered by a 1/4 horse electric motor.

    Not intending to offend anyone, but being told something and having it be a fact are often not the same thing.

  29. I run a screen on my car. It's a gasket with a screen between two gaskets. I'm alway surprised at the end of the year how many rocks were prevented from going down into the blower. The screen has about 1/8th inch holes. I won't run without one.
