LT4/LT1 rebuild Hello so I have a 2018 GMC Sierra 1500 6.2 ls86/Lt1.
I need a new block and I was wondering if I could use a LT4 block from a 2023 Cadillac Escalade.
Now I do know that the LT4 is supercharged in the Cadillac. I already have a BTR cam I bought for the LT1 long story short are my parts interchangable? Will this block work for my rebuild without many modifications?
Thanks in advance

As far as I know the LT1 and LT4 blocks are the same. Its the crank/rods and heads that are different.
