Hello all. I purchased a '17 Silverado short box regular cab with an L83 (5.3 liter) and 6L80 trans. I'm very interested in doing a swap to the L86 (6.2 liter). I've searched youtube, and forums and can't find anything useful as far as data. Has it been done? Where would you suggest I look for more information? Thank you.

 

It's been done, probably not a lot of forum write up's about it though.

It's likely best to find a very similar year engine because I know that the 14-15's and maybe 16's run a different electrical connector at the high pressure fuel pump than the newest engines. May want to research that a bit.

After the engine is in, the rest is just a tune to make it run like a factory 6.2. Should with the key word being "should" be a pretty simple copy/paste of engine data over the top of the 5.3 tune.

 

That is great news. I appreciate the input. I there a specific tuning software for PC that is preferred?

 

software for the most part comes down to preference most around here use HP Tuners or EfiLive, might see what the local guys by you are using in case you need help might make it easier on you

 

I very much appreciate the input. I'm going to start the process of find a good L86 and start a build thread. Thank you!
