I don't know the specifics of these two blocks, but changing engines
would in general, change the clutch adjustment.
Consider that the clutch is all mounted to the engine, and the throwout
bearing is on the transmission. A small difference in how far the clutch
extends out from the engine would change the engagement point a lot.
But, since these are hydraulic, I don't know what you would adjust. Hmm
