Silverado NV3500 Info Needed

[cebra]

I have been doing a ton of research about the NV3500 but I wanted to try to confirm information.

Trans: 2000 NV3500 (came off a 4.3L)
Engine: 2000 4.8L (originally automatic engine)

What I have found out that the 99-00 Manual 4.8L Engine had a longer crank than the 99-00 Automatic engines and the 01-06 Manual Engines. This has posed some questions for me.

What I have is:
02 Flywheel (Sachs NFW1050) - heard this is thicker than the 99-00 due to the different crank
02 Clutch Kit with Pilot Bearing
00 Throwout Bearing

Is the 00 throwout bearing the same as the later years (just without a feed line)? Do you see any issues using the 00 throwout with the later model clutch/flywheel? I am hoping they are the same as far as extension and the short crank on my engine is compensated with the later model/thicker flywheel if that makes sense.

See the Novak writeup about crank extensions on the GEN III LS motors. They have recommendations for clutch and flywheel selection at the bottom of this page along with a link for more details.

Make sure you don't have one of the 3/4 ton 4.8 with the GEN I crank projection and LS bolt pattern.
