5.3 to nv3500 want to double check before I install please

[Homer ak 94]

Good evening Homer. New to this thread and working through lots of info. It looks like you completed exactly what my son and I are attempting. A 1994 GMC 1500 4x4 - had 4.3 V6 originally. Putting in a 2006 6.0L and bolting up to original NV3500 5spd.

Wondering how your project turned out?

I had test fit the engine to the tranny using a 4.8L flywheel (LUK LFW387) and the throw out bearing did not contact the clutch. I am hoping the fly wheel is the issue.

Hi, it turned out great! Im very pleased with it, i used a sachs flywheel and a stock to my original setup clutch plus a pilot bearing from napa that i found a part # for by searching through this forum, if you have more questions we can connect through fb maybe

I’m about to swap a 99 5.3 into my 2001 rcsb 2wd truck. Originally a 4.3 5 speed.
What exactly do I need to mate the 5.3 to the nv3500?
Is it just a 4.8 flywheel? My truck just got a new clutch kit installed but the engine decided to torch the head gaskets haha. Hoping I don’t need a whole new clutch assembly......
