    Fuel injection questions

    Gentlemen,
    Its been awhile since I posted here. Since thelast time I was on I have managed to get my 472 stuffed into my 49 Ford truck and its driveable. My plan is to to go with fule injection. I managed to scrounge up one of the old port injected manifolds complete with injectors, fuel rails, and throttle body.

    What I would like to do is to adapt modern electronics to the old hardware as the original computers were expensive and finicky. Has anyone messed with anything like this? I was thinking I could adapt the ECM from a late model GM vehicle with a port injected V8 to control the injectors.

    Any thoughts??

    Bobby

    If I were you, I would check out the Megasquirt controllers. I've heard really good things about them, and was going to go with one myself until I decided to stick with the carb. http://www.megasquirt.info/

    Re: Fuel injection questions

    I highly recomend the mega-squirt controller. I've been running one one a 53 Stude bracket car with a 500 cad for a couple of years. I can't race as much as I'd like but is is fun tuning in the pits with a laptop. I used an edelbrock manifold, I welded holley injector bungs in it. I adapted a BBK throttle body for a 460 ford truck to it. There are better ways then that tb but I run a large prostock type hood scoop so I had lots of room. I use 39lb. injectors which should be good for 500 hp but I'm not at that level yet. Have fun

    There are several "ready to install" setups you can buy for old carbuerated engines.
    Just shop around.
    It would likely be easier to install a "kit" than to try to piece something together from some other application.

    Re: Fuel injection questions

    Just a suggestion... Maybe a complete aftermarket EFI setup for BIG Ford motors (460) and a Cadillac to Ford 460 intake adapter (spendin bucks, though)


    Since you have all the factory goodies, a standalone controller is most likely a workable route
