    Well, I was bored the other night and started surfing E-bay. I found a guy in Auburn, WA that is selling a 67-3B. I had to look twice at the ad because it had a 225 with the pro-jection :shock: . He wasn't sure if it was odd fire (I don't think they made even fire 225's?). I sent him an e-mail and he said he had the system sitting in his garage and decided to throw it on. It's the older 2bbl. setup with the knobs on the box. According to him it runs fine. It's wired in just like the instructions say to the dist (now HEI).
    I'm trying to talk the wife into buying me one for X-mas but, I need tools to do some home repairs :rofl: . I'll give it a try when I come up with the $ and let you'all know how it goes. Anyone need a set of almost new BFG AT's? :twisted:

    I traded email a few years ago with another guy running pro-jection on a 225. Said he just put some smaller jets in it.

    Wonder what those older systems sell for these days? And what type of manifold required?

    Not too long ago I chatted with a guy who had an early 5 with a Pro Jection setup on it. He also said it ran fine. A guy in my local club has an older system on his Dodge 360 and loves it. He offered to let me try it out on my :v6: . I might take him up on it once I am driving again. He says they can be had for around $200 if you shop ebay and other classifieds. I still think I am going to use the TBI route because the pro jection has no way to sense engine load and I am a dork. :D

    I thought the Pro-Jections used some sort of mainifold pressure sensor so they could determine load? Maybe a Vortech 350 would be a better bet ;) .

    I was looking at the Megasquirt homebrew fuel injection for my 4.1L. I have been looking a little into it, and it seems to be pretty cool. I will have to hunt down the link for the website.

    You have a short dipstick. Would using a Megasquirt and a short dipstick pose a problem for you Dan?

    :rofl:

    The early Non-digital Pro-Jections used rpm, coolant temp, throttle position, and with the add-on kit, an O2 sensor to make self adjustments. Without the O2 add on kit (closed loop) they don't self adjust as well. Especially for altitude. They can be manually adjusted however at the computer. Despite this they work pretty well. Never tried one on an odd-fire though. I would think the older set up would work better on an oddfire than a digital though because of the complexity of the newer system and the amount of control the computer has. Seems like the computer would get confused with the odd crank firing pattern without some serious distributor work.
    I'd like to see someone change jet sizes on the Pro-Jection, it doesn't have jets! ;) They may have changed the injectors and put a smaller flow rated set in though.

    I paid $150 for the set up I have sitting on the shelf right now and that came with everything but the coolant sensor. Even got the manual and fuel pump with it! That was several years ago at a swap meet. I've seen them occasionally since then for about the same price. Sometimes with more goodies than I got with mine! :cry: Nickmil.

    You know this topic has popped up so many times I think some of us ought to get on the phone and discuss a means of building a universal junkyard kit to put TBI on our Dauntless and Hurricane engines. It can't possibly be that hard. I would be willing to make brackets to make an RPM sensor for the front of the motor and adapters for the manifolds for the cost of materials and shipping. Surely someone on here knows how to sort out the electronics and the right model of TBI unit to use. What do you guys say is anyone else interested? I would think we could get them working for a couple hundred dollars.

    I'd sure love it if we did, but am clueless when it comes to wrenching at that level (I can follow directions, thats about it... :rofl: )

    I could do anything related to getting info out on the web...

    Mike I have often thought the same thing....It seems GM is pretty tight lipped about the computer codes in the ECM......

    I am actually eager to leanr fuel injection now. I have shunned wiring and computers for the jeeps but i am starting to understand the differnt sensors now :)

    Wasnt Steve in Denver already installing an oddfire fuel injection on his motor?? Steve you out there???

    I have a friend with a 74 TLC, original straight six that he put a Chev. injection system on. It is obviously a completely different set up but he told me he could make one for my 71 that would work. I'll ask him what it is out of and let you all know.

    Hey Mike, let's do it! I know a guy who did it on his engine but unfortunately got rid of all the parts. Basically, if you can scavenge a TBI system (with ECM, electronics and harness) off of a 4.3L V6 (93-94 is probably the best choice), all it takes is a crank sensor and the bracket we talked about (oops- electric fuel pump also). You don't need to find out about computer codes or programming because the whole point of it is to fool the ECM into thinking it is still operating on a 4.3, thus it uses the same logic and strategies. I have two weeks off for Christmas- my place or yours?!?!?!?

    The plate has been welded, the box is in, the column has been mounted. With a steering shaft my Jeep will be able to drive on its own. Stopping is another issue altogether though :D . I'm a newbie to fabrication but EFI is my specialty.
