expectations...
The 5.3 would make good power without going to a 383, but spool time will be decreased and it will take more boost to do so. Turbo will be at the same efficiency with either 15psi on a 383 or 25psi on a 325. Well not exactly, but very similar as the 96/88 wheel can easily support 383 cubic inches.
