I’m looking to build a 6.7 stroker for my 2015 GMC Sierra for towing my travel trailer. It has the 5.3 K2XX Gen III now and I need to know if the LY6 and the L96 blocks are compatible. Basically, I need to know if everything will bolt up to the block just as it is now. I don’t want to do any mods except for the short block itself.
