On these boats you floor it and wait, sometimes the wait is well over 30 seconds which seems like eternity. I have also been driving a boat that would simply not plane off until some of the crew moved into the bow. In these situations the motor reaches near peak torque as it gets up over 3000 rpms or so. This allows the newer LS series motors like the ZR409 or ZR450 to get into the torque curve where there is a difference and therefore my experience is that they get on plane quicker. As you also mention the LS motors also spin higher rpms so the loss of top speed with flatter props is less.
