    That's a fact! The best prices around are from Wait4meperformance.com Ask for Jesse and you can tell him Bret from F-Body Central sent you. He can sell you a GM PCM with a stock tune or one tailored to your needs. His prices can't be beat!

    Could you measure from the fire wall to back of cylinder head clearance also could you also measure from front cylinder head to radatior support I,m getting ready to set in my ls-7as soon as its back from the dyno doing some new stuff to it. Need the measure making sure the coil bracket fits behind the head also making a billet dry sump tank holder that off the front of the engine so i don,t have to cut a hole down by the battery tray like a lot of people do with ther first gens thanks

    Why did you have to modify the cross member? What didn't clear? With the setback edelbrock mounts, did you have to mod the transmission cross member?

    The GM "aftermarket" ECM is locked but most "aftermarket" controllers are programmable.
    I'm looking at the M-90 from Mast for this combo.

    The stock GM ECM/TCM combo is about $400 shop cost to run the LY6/4L80E. Plus a harness, tuning, throttle pedal, assy.

    We didn't modify the frame crossmember.

    Regardless of what engine mounts or even engine you use, a 4L80E will require a custom transmission crossmember.

    By "GM aftermarket" ECM, are you reffering to the one in the GMPP controller kit?

    Thanks,Joe

    Yes,
    I wouldn't use it. Too limited at least at this time.

    Ah, I see. I'm going to be bolting mine to my existing 700r4. Read the instructions for the edelbrock mounts and they don't mention the need to modify the cross member. Guess I'm over thinking this.

    Here are the online instructions:

    http://www.edelbrock.com/automotive_new/misc/tech_center/install/6000/6701.pdf

    Interesting to note that for our cars edelbrock says the 12577901 (cts-v) oil pan is recomended. For all other cars the expensive milodon pan that requires a remote filter is required.

    It seems that if you have access to a Tech II (from my understanding) you can put a VIN number in the GM "Aftermarket" ECM and then have the ability to program with any of the current tuning software programs.
