let's just say if this was an option that bmw offered to put in my m6, I would have clicked that option
ohh yeah you could also go to the dealer and pick up the crate motor for under 10k w/o a core charge....
The boss motors wants to rev more or freer, but not a major difference. I drove them back to back. You feel the top end more as well.
But like you said the major differences are internal, heads, crankshaft, pistons etc
