    I've been researching the Holley ECMs and would like to know which version you have plus what your doing for complete ignition system and also details of fuel supply along with where the fuel lines / pump/regulator are routed/mounted---------------

    Jerry,


    I wish I could be of more help to you. I know very little about the things you're asking. My Hilborn electronic unit was installed by Midwest Rod And Restoration in Wapello, IA. They have a website. Contact Shawn Maine at: webmaster@midwestrod.com. I'm sure he can answer your questions. I have an appointment to take my car to Karl Performance in Des Moines, IA for a dyno tune. They are another good resource. Their head tuner was Karl Moyer's crew chief when Karl was national pro-mod champ. Hope that helps.

    Hey Tom,
    Glad that the lead to Karl's panned out, and hope it's indeed a good link for you and they solve your problems. If you could, ask them to detail what they find, and what they do to correct your issues and report back. I'm super interested in tuning tips for EFI's.

    The aluminum block is used for the MAP sensor. Probably not the best(too small).DSCN0515.jpg KC

    You may want to talk to Bob Ream at Imagine Injection very knowledgeable.
    Imagine Injection - "Home of Quality High Performance Fuel Injection Systems" or ph 602-377-4093.

    He did the machining on my Enderly manifold.

    Tom,
    Not sure if you've been to Karl Performance yet or not, but I don't think you'll be disappointed in any way with them. They are great people, and they are turning out some fantastic machines with fantastic power plants. Ron Hidy, their Sales Manager, really bent over backwards to help me out of a jam Friday when we lost a pair of rocker arms while in Des Moines. While they have been focused on Chevy's they recently pushed out into the 347 Stroker area, and they had what I needed. Great people, and you'll have plenty to look at while you're waiting for them to sort out your injection tune.

    Glad to hear that you got it sorted out! Did Karl's figure out the linkage issue, or was that something you did apart from them? I expect with eight butterflies any slop in the links is too much.

    Update...The car's running great. Relocating the throttle linkage to the middle of the intake from the front end of the intake did the trick. Evidently the rod that the butterflies are attached to tends to flex ever so slightly when activated from the front of the engine...in other words the rods torque or twist. And the butterflies have to be perfectly in sync. Relocating the throttle mechanism to the middle of the engine eliminated all the spitting from the stacks. Result...happy car and happy driver. The Hilborn EFI and Holley ECU work perfectly. And, Hilborn 8 stack injection just looks so cool.

    Roger, it was Andy Starr at Hilborn although there was a guy that worked for Karl Performance that worked on their sprint car engines that said the same thing as Andy regarding the throttle linkage location. And, yes, you're correct regarding the butterflies. There can be no slop in the linkage at all. Once you get the Hilborn EFI dialed in and installed correctly it works like a dream.
