Got my new motor and trans. They came from a 2018 Escalade that was wrecked with 3K miles. Purchased it for $4500, not bad.
The motor is an L86 and the transmission is the new 10 speed 10l80. These Gen V motors are not like the Gen IV truck motors that were different from the LS2 and 3s. The longblock is the exact same GM PN, the only real difference between the L86 and LT1 is the accessory drive, oil pan and intake and I'll be addressing these soon.
The general consensus is that these are a more difficult swap than an LS motor but its really not. Perhaps a little more expensive but not by much.
The motor looks pretty big fully dressed sitting next to the big block I pulled out. The trans is massive, my 700r4 is in the background and hard to tell but its a few inches longer, taller and wider.
