    Th350

    What's needed to fit a th350/th400 to a 4.8/5.3 motor? I know the bell housing will bolt up, but not using all the bolt holes on the motor.

    The flex plate needs to be swapped. I believe B&M makes the one you need.

    Get the 6.0 flat flexplate and spacer. That's what I used. Got it all for around $70. I think I got it from pace performance.
