Need parts list and fact check-in 2000 1500 4.8 5 speed swap to 2003 5.3. Owning a 2000 4.8 5 speed 4wd swb Chevy has been baddass but after 312000 miles it's a little worn out. I have a purchased a a 160000 mile 5.3 out of a 2003 avalanche. Computer all accessories be an easy swap into the truck. Except FOR THE .400 DIFFERNCE CRANK.
SO FAR IK I NEED
-nfw1050 flywheel-(sapposed to weigh 40lbs-is this bad)-what do I have to do with the dowel pins?
-i need longer flywheel bolts-part number please? Ik my 4.8 bolt are too short bc of the .400 diff.
-do I need different pressure plate bolts? Mine from my 4.8 won't be the same?
-i keep hearing about a extended pilot bearing? But if the nfw1050 is the same flywheel for the 2001-up trucks then can't I just use those years stock pilot bearing.
Otherwise I've found part number 12557583 for the ls7 pilot bearing.
One more thing is will the computer have to be flashed b4 the truck will run with a different computer?
I have seen lots of posts about this but none that litteraly give me the right part number and for my exact occasion

If your 5.3 crank is long, that's a game changer, get that changed out for a short one, first thing. The nfw1050 mandates it.
-I'm not sure why you plan on using different dowel pin setup or flywheel or PP bolts.
Bolts are not torque-to-yield u less their smooth section is specifically reduced smaller than the threads. Use blue loctite and re-use.
Dowels depend on how the PP bolts (lack an) indexing smooth area. Buy stuff for a 4.8 truck, good to go. Unless of course you're trying to be 100% prepared and can't run to the parts store.
-The 4.8 ECM will run the 5.3 enough to drive to get a tune.
-The pilot trucks used isn't a big deal, if you get none, or the wrong one with your new clutch, buy for an 02 Camaro if you need the small, for an 07 CTS-V if you need the big'un.

I was aware that all 5.3 had the short crank. My 4.8 had the long crank. The nfw1050 flywheel will make up the difference. But because of the difference I need longer flywheel bolts.
