Swapping an L86(6.2) into a 5.3 (L83)

Recommended Posts

Hey everyone,

I just completely blew my motor up yesterday in my 2015 Silverado 5.3 w 6L80. I am wondering what it takes to swap the 6.2 into my truck. as far as harnessed and what not. id love any input i can get.

If you buy a 2014-2015 6.2 engine it's basically plug and play with the harness, nothing is really different. The later years after 2016 I believe run a different high pressure fuel pump so the connector is different.


The rest is tuning.
