How I did 5.3 to nv3500 5 speed

[tbr89gmc]

I'm going to post what I did to mate my nv3500 to my 5.3 since I wasn't able to find any reliable info when I did my swap. I bought the flywheel from oreilys. The pilot bearing is an 43.3 mm od with 15 mm Id that is a special bearing that I only been able to find at NAPA. This fits in the end of the crank with no spacer of any sort. The release bearing may be hard to find, but I found one on ebay with this part number 1377c. I used my stock clucth and pressure plate from a 95 chevy truck. With these parts I didnt use any sort of flywheel or pilot bearings spacers and cost less than $100. If you find this useful let me know.

Thanks for the info!
Been looking for part numbers for a while. Just ordered everything at just $100.
Now to pull the motor and put this in!

if you're doing an LS engine to a NV3500, all you had to do was look at my build thread. 4.8 flywheel & clutch kit bolted right on to my 5.3. been running 16,000mi with no problems whatsoever

What year is your truck? 2wd or 4wd? What size motor was in itfrom factory?

I used my stock clucth and pressure plate from a 95 chevy truck.

It's 4x4 with 305 but 350 pressure plate should work also

What, is, the difference between the throw out bearing listed....than the stock 3500 throw out bearing? I have read you can use the stock one. Just wanna double check before I mate 5.3 and 3500

I'm still using the stock throw out bearing.
