    So I have convinced my father to ditch his carb on his 79 lil red Express truck. The problem is I haven't had much luck on finding info on tbi installs on the Chrysler 400 bb that is under the hood. I guess the first question is.... is it even possible? How hard would it be to convert the distributor? Would I need the 454 tbi or the 350? Any help would be greatly appreciated.

    If 1979 is an Old Classic, I must be a real rusty Antique!

    I'll try to get more pictures when I can. But here is a couple up close side shots, and the bronco bumper we put on it. [​IMG][​IMG][​IMG]

    There's no difference in converting a Mopar 440 to TBI then any other engine as pointed out in the FAQs.
    The mopar electronic distr pickup is compatible with the GM ignition module and is shown in the distr conversion FAQs.
    As noted in the FAQs, chose the parts from an engine that closely matches yours.
    So a 454 would be closer to the 440 then a 350 TBI would be.
    I have complete kits as well as parts for the DIY guys.
    My harnesses are custom designed to fit, custom tunes for each engine and CNC adapters.
    See the links in my Sig below.

    Injection is NOT a Dodge thing so going to a Dodge site to discuss a misfire on a stock 360 isn't going to help convert to injection.

    I definitely appreciate you input Bill. If it wasn't for you my 79 Cherokee would still not be running. The dodge has a 400 big block out of a 74(?) Chrysler Newport in it. I'll check out all the links you posted. I'm not to for sure if he wants to build a kit from the junk yard or order a kit from you, but if he builds it I'll definitely be interested in a program from you for it if you are interested.

    Would think that would go without saying. Figured at least some common sense would kick in. Since he has a nice Dodge it was simply a link to the mopar site . With the OP only having one or two posts was unsure if there was a mistake with a site choice for that question or not.

    Yeah, I've been more of a lurker than a poster. I dont personally own an IH, so I mainly hang around for all the tbi knowledge. The dodge is my dad's and I own a jeep.

    At 400ci, your on the edge of TBI choice.
    A regular driver that's just used for normal driving, the standard TBI will work.
    It's about 500cfm.
    If any towing or performance is wanted then the 7.4 TBI would be the choice.

    Fill in the fields below (example: 5000 RPM), click calculate, and we’ll show you the optimal cfm for the street and track! The ratings are different because street engines have a volumetric efficiency around 85% while racing engines are closer to 110%.

    Maximum Engine RPM : 4000
    Engine Size in Cubic Inches : 400
    Street Carb CFM : 393.52
    Racing Carb CFM : 509.26
