With 4000 Lbs to push and a single prop drive, you should be focusing on reducing prop slip and getting the engine to rev to or beyond the recommended WOT RPM with a typical load. Thus, I would advise getting a 4 blade SS prop that lets the engine get to 5000 RPM at WOT, even if it's only rated for 4800 RPM or less. That 5 liter is a small block Chevy engine that will happily turn 5200 RPM without any issues. The 4 blade SS prop will provide excellent prop slip numbers and allow as much trim as the boat will take without blowing out.
