    Well I wanted to start a new post that I can update and keep track of my progress. I have been working on this truck since I was...14! and seeing how I will be 30 this year I have to get my act together! So a big step in getting this conversion back on the front burner was finding an affordable 6.0L engine.



    Score!! I know the SS is dirty but in MI it snows
    I have moved the frame to the heated garage so I can try to get this beast to the track this summer/fall

    Here is a close up of my find...


    Here is the first question, what is this broken sensor?? it is at the back of the intake on the very top?

    any one know how much this will cost$$

    Now my next project is how far do I strip this engine down to make it easier in the install??
    For my engine experts how far can I disassemble w/o requiring a gasket set???

    one other broken part that I have found. I think it is part of the return fuel system. it looks like a referance from the intake to the fuel rails??


    I will try to post updates in this thread w/an announcement in the main message that I have added an update.

    thanks for being such a valuable source of quality information.

    I don't suppose superglue with silicon seal around the broken are would suffice. LOL

    Otherwise, can hopefully find a replacement intake from someone cheap. There may be someone selling their stock truck manifold due to replacement with a LS6 or VicJr. Never know. Good luck!

    Update:
    that little piece of MAP casued me to pull the intake...I need new intake gaskets??? any Ideas


    I also fixed the broken fuel reg (I think??) vaccume ref port. I used some JB weld, I hope it works...my next solution was to remove the PC valve and use that port but I need more info about removing the PVC system and adding catch cans?? suggestions??
    What is that line with the green plug/port? it runs to the top of the manifold in the front and to a hard line in the back???


    next pic is the two wire bundles that I need to fix/connect
    this is the one that goes to the trans


    this is the smaller one that goes out the back of the engine

    Be extremely careful on wiring the trans connector, it is extremely critical....alot of the wires are the same color, u must look for stripes and the size of them sometimes helps....once again be very careful...I pulled the wires out of the pins when removing my tranny the first time...so been throught that and it stinks. Make sure to use good solder on your connections...dont just twist the wires together and black tape them. solder and heat shrink then maybe the tape.

    good luck

    2.1.07 update.
    Got the motor mounts and started putting them on. But the passenger side hit the AC...so off goes the AC compressor and the EGR stuff on that side too, it looks better the more crap I take off.
    Mount and plate


    Plates on block, I am guessing I could fit the AC bracket to work, but the plug it hitting the mount...so I will wait to see if I need AC


    Plates and motor mounts. I did not like the 'feel' of the motor mounts they seem weak



    I am working on the block of plates and figureing out what I will remove/unused. What has anyone else removed on their conversions??

    I know what you mean about the A/C issue. I just flipped my plates around, thus it will move the motor forward in the truck. With that, you'll be able to bolt the A/C compressor.

    Now, you can always spin the extra $$$ to get a Sanden kit. I just didn't want to spend the money. Guess what... I still don't have A/C yet. LOL I need money BADLY!!!
