Official NBS 4.3v6 to GEN 3 V8 swap Guide

[Mxer391]

just make sure to match your slave to whichever style clutch line you have. the 05 truck should have the slave with a roll pin. the 99-01 setup has the quick-connect at the slave.

So then I should get an 05 4.8 clutch and flywheel?

01+ Clutch and flywheel are the same up to 05. (No v8 5speeds in 06). He's talking about your throwout bearing and slave cylinder. Match those/

Hi everyone,

I have read everything I can and haven't found a clear answer so at risk of being scolded for not searching I will ask you guys. I have a 2003 Silverado 1500 RCSB with a 4.3L V6. I will be swapping for a 6.0L and found a 08 6.0/4L70E combo with all the trimmings. Am I looking at the same swap mentioned here? Does the 08 engine require anything beyond the scope of this guide? Should I start a new thread?

Nothing overly extravagent. A box from Lingenfelter to covert the 58x crank signal to 24x, tapping the side of the block for the Gen3 knock sensors and extending the cam sensor harness. Oh and the Torquerush X-link to run the larger throttle body.

Thank you, Frenchy. I will post pictures and my experience when the time comes. Hurry tax season.... I am ready to pass somebody on the highway without concern that my gutless v6 will be able to accelerate up a hill.
