The 5.3 LM7 should be bored for a pilot bearing as well. After all, it was the same crank as a 6.0, which was optioned with a manual.
Put a 4.8/6.0 flywheel on the 5.3, and you'll be within adjustment distance of the original small block.
The Vehicle speed sensor could cause some issues. I'm still looking into that on a Gen 4. I also intend to get an accurate enough signal through the computer to run a stock '91 speedo.
Some random measurements and notes of mine are found here.
