The 6.7 is an entire new generation of GM small block. It’s a Gen VI engine, not a Gen V. Some differences include (aside from the displacement)
Dual port and direct injection
Fully forged bottom end
Different intake
13:1 compression
Probably different cam, heads and valve sizes.
Probably a different size throttle body (too lazy to google this and the one above).
It is going to be a neat engine and I am excited about it. I just hope the piston ring end gaps aren’t as tight as the gen V stuff but it most likely will be unfortunately.
