So I just bought an L96 6.0 out of a wrecked 2015 Silverado 2500 with 35k miles. I currently have the iron block LMG Flex Fuel 5.3 with a Black Bear 89 octane Performance Tune and the AFM disabled. What all will be required for the swap? Will it run on the 5.3 tune (at least good enough to drive for a new tune)?

It should bolt right up to the 6L80E correct? Will I need to drop the trans?

Also was thinking about doing some LS9 head gaskets, ARP Head Studs, and Trunion Upgraded Rockers in case I wanna go turbo later...any other suggestions?

This will be my first engine swap, planning on grabbing an engine lift from Harbor Freight...Ive done a couple cam swaps, installed new clutches, headers, etc...

Thanks for help guys....

Pic of truck....has 96k miles, 5.3 runs fantastic, good oil pressure and mileage just want a little more power

 

We have done ls swaps with different ecm stock tunes, 5.7 tune but lq4 6.0, runs good.
4.8 tune 5.3 swap, runs good, these are all gen 3 engines though
