    OK, I'm game. But I was waiting until I was finished. But I can show a couple of things: Haven't figured out the insert image tool yet. So I'll have to post the photos at the bottom. You'll have to match the photo with the description...
    1. Finished Duraspark Disty
    2. Glove box with ECM. SES light upper left next to radio.
    3. EST/coil mount plate
    4. Firewall power center. Fuse holder, OEM Fuel pump relay/MAP sensor & power relay for Ign, ECM, and O2 sensor heater.
    5. Still Spaghetti.

    Obviously still a quadrajet. Waiting for the Transdapt adapter plate.

    I have new valve covers and intake plenum to photo when everything is finished. So more pics to come.

    Well I guess someone has to go first....
    Here is the engine compartment, just a little more cleaning up to do and wrapping of the wires and it will look pretty..

    -----------------------------------------------------------------------
    This was the part that really had me stumped for a while and I thought I'd share what I did with others incase someone else ever had the same problem.
    I have an older chevy engine and it does not have a threaded drain plug into the water jacket for an knock sensor. And the one threaded plug I had was a little bitty thing right behind the collector on my headers.
    So I got creative, I got a steel freeze plug and a threaded adapter that the knock sensor threaded into and then drilled a hole in the center of the freeze plug. Threaded about 2 threads thru the hole and then carefully welded a tight little bead around it and checked it for leaks. Go figure I got it on the first try. Hammer in the new plug and thread in the knock sensor. There is enough room to get a wrench on the adapter so when I put in or take out the knock sensor I don't have to worry about twsiting out the freeze plug.

    I pretty much followed Bill's instructions and it went real smooth.

    I'll play!! Since there are only a hand full of use FI'ed 80/800 guys I better post up. :D

    I too followed most of Bill's instructions, only I modified then a tad to fit the 800 as I saw fit.

    At first Bill and I were worried the distance from the manifold connection to the MAP sensor was gonna be to far and might cause problems. No ill effects as of yet.

    I will say the fuel system mods are the biggest hurdle to overcome when doing a 800 conversion. Means of fuel return to tank have to be added, the OEM suction line into tank is to small so it has to be replaced, then ya gotta multiply all this by two so you can use the other tank when finished also. I have yet to hook my other tank into the system. :eek:

    All though the FI conversion is the only major mod I have made on the truck, I'm gonna be hard pressed to find a better one to do later on!!! It don't get no better than WORKING fuel injection!!!

    Thanks Bill!!!

    This conversion may not be on a IH motor. It's a SBC BUT nevertheless I'd like to share some initial observations going from a Quadrajet to TBI. May be this will help some of you that are contemplating a conversion. Bill-USN1 helped me out on a couple of bin files from the ALDL data. I studied the changes he made with the corresponding ALDL data and got the hang of it. Thanks for the help Bill! I still have a lot more tuning cycles ahead.

    Pros:
    -Cold start is great. No more waiting for warm up. Start it and go
    -Idle is solid
    -No hesitation throttle response
    -I can run 87 octane now. I had to run 91 before
    -No more foul plugs every 5K miles
    -You can tweak (tune) forever (if you like to tinker)
    - Tune and not get greasy.

    Cons:
    -Initial mpg is 10.5 vs. 12 for the Qjet (Initial chip was set up too rich and timing was off. I am pretty sure when tuning is done, TBI will beat the Qjet on mpg)
    -If you want to program your own chip, it requires an initial investment in a programmer, UV eraser, laptop and Eproms.
    -Need patience.
    -Cost

    So if you are on the fence, just do it. It’s worth it. These are just my views. Your mileage will vary……

    Here is my Scout on TBI:

    '72 Scout II
    Worn out 304
    T-19
    Dana 300
    SOA
    Full width Chevy D44/4.56/Lockright/Discs
    Full width Corp 14 bolt/4.56/Welded/Discs
    36" Irok
    Aggresive fender trimming ;)
    Bobbed rear
    Cage
    And just about nothing else.

    So far I have been running for about 10 days. I still have some data logging to do and some tuning to do. But it makes great power - starts easy and doesn't stall!! I can lug it around at 400 rpms. BUT - I have a poor idle and I'm still nervous when I drive it around. And the racket the fuel pump makes is pretty bad!

    REAL EFI PICS TO COME!

    Here's a few pics of the MS-II conversion I am doing. It's still running on the Thermoquad. MS-II isn't recognizing the dizzy signal. I stuck the MS box in the glove box with the relays and fuses. Aslo a dew pics of us goofing off.

    Here are some pics of my continuing project. Bill USN-1 and this community deserve most of the credit for this project being as far along as it is... and it is almost dialed in. I would have posted sooner...but I needed to use my wife's camera :eek:

    The guage is from Northern Tool, PN 53653. The fuel pump is from NAPA, PN P5001.

    I need to redo a couple of wires in the harness, which you will see in the pic. They tell me they use a machine now, so this shouldn't happen.

    Some more pics. I am using the stock air cleaner right now as you can see in the pics. Because of the TPS sensor (mine is taller then some of the pics I've seen) I had to use a 1/2 inch spacer...that I found someplace. I need to find a cold air source to supply the TB. I like the Caprice unit the Airaid-type unit I have seen pictures of in this forum, but I need to find someplace to run a snorkle. Any suggestions?

    You can see one of Bill's chips in the ECU. The ECU looks pretty banged up, but works fine. Interesting to note, I have another ECU I pulled from a local JY that looks brand new. When we finally dial this one in, I am going to try and set it up as a spare.

    One thing I would do differently, or will do differently the next time :) is use a longer harness. Another 1.5 - 2 feet and I would have been able to put in in my Tuffy center console. Something about the computer in the glove box...some kid breaks in and grabs it thinking it is CD changer or something, and I'm stuck.
