    Thanks guys! I may go ahead and look into doing that LS1 pan. At the moment Im working on getting my intake ready to put on. Im going to run a TBSS intake with the older return style rails. Just finished welding -6 AN bungs to modify the crossover. Got some LS2 injectors as well!

    Great looking build! I didn't see what cam you went with. I'm assuming you're not keeping it stock with those heads.

    No, not keeping stock cam. I'm running a Thunder Racing custom grind. Its their TRuTorq Level 5, 227/239 .614"/.621" 115LSA. I know a few people locally running it in their trucks and they have made good power with it. Got the intake just about finished and going to work on the fuel lines next.

    Nice looking truck. That has been my favorite color on the OBS trucks. Im subscribed to this one as mine seems to not be going anywhere till the weather breaks.

    Been a little while since I've updated. Installed a Tru-Cool 40K trans cooler. Had to modify a few things and made some brackets to mount it and make it work but I think it came out good.

    BEFORE:


    Sectioned this front support to make room for cooler.


    And here is the cooler installed.

    Got my intake fixed up too. Modified the stock 99-02 fuel rails to keep the return style system. Also added a Nick Williams 92mm Throttle body!



    Here it is installed.


    This is where I'm currently at. Ready to start the wiring. I have a new stand alone 99-02 harness I will be using so that should make things a little easier.
