    yes it will bolt to a 5.3 but don't do it. Its only truly good for a straight across 4.3L exchange. Since you're going 4.3 to 4.3 thats fine but a 5.3L tranny won't bolt to the 4.3L setup.

    No, you can use the 4.3 trans with the 5.3, just can't put a 5.3 300mm input transmission into a 4.3L engine setup.
