275 HP at the wheels is a joke for a mild-built 360 with mostly stock parts just sayin'. BUT you can't just crank up the boost when you want more unless you build the whole bottom end for it and then still it's argued that the max HP an SBM block can hold is 6-700. I'm going the G3 Hemi route myself (eventually), they'll hold 1500 HP with just some drop-in forged pistons and better rods if it's a 5.7L plus you get way more torque and HP with less boost (and a lot more low-end) compared to a 3.0L inline-6. Just thinking out loud not trying to convince you one way or the other.
