also, rev ups have a intake manifold redesign + internal strengthening + exhaust valve timing to give the revup engine more upper power. yet, they are robbed down low (below 5k rpm)

better oil pump.
stronger rods bolts.

The engine trades low end torque for higher rpm power. In an automatic, you'd be slower with the 298hp Rev-Up engine hence the reason the motor is only offered with the 6MT.
