    It took some time to find the specs:

    Gross lift .410 intake .427 exhaust
    Duration at .050 207 intake 214 exhaust
    Centerline 117
    LSA 112? (I would have to call and verify it)

    Intake opens 14 degrees btdc and closes 41 after bottom
    Exhaust opens 43 btdc and closes at 9 degrees after

    I meant to post specs earlier, but was working from my phone until now.
    93 Chevy pickup
    357 engine fresh rebuilt
    2wd short bed/ short cab
    Rebuilt 4l60e transmission
    Electric fans with thermostatic controller
    Overbored throttle body
    Vortec heads with gmpp intake and egr piped
    Vortec fuel pump, 18 psi spring on stock injectors
    MSD 8.5 mm wires

    I didn't write the computer number down, the little time I had to work on the truck today, I chased starting issues (dead battery).

    I have chewed the long to do list down to setting the distributor and the computer.

    I remember reading a good start up guide for first time walk through on a forum (third gen if I remember right) and I will re post the link so I can help any one in similar circumstances.

    Please let me know if there is any way I can contribute back

    That is the same PCM that is in my 93 K1500.

    .adx is for data logging. This is used to monitor the engine when it's running.

    .xdf is for editing the .bin file (PROM PROGRAMMING). This is used to change timing, choke, fuel, AE, PE and dozens of other parameters. Reprogramming the .bin file is the ULTIMATE TBI MOD! Reprogramming the .bin file is 100% necessary to get the best possible performance for bolt on engine modifications (vortec heads, aftermarket camshaft, aftermarket intake system, aftermarket exhausts systems, more fuel pressure, and larger throttle bodies). Reprogramming the .bin file is like changing carburetor jets, distributor weights, and distributor vacuum advance.
