If only the very ultimate pump is what you're looking for then this is it
The 12JR Race Pump uses a severe duty 17-4 pump shaft, a lightened, balanced,
and blueprinted stainless steel impeller, an inducer pre-loader impeller, and a double drilled bowl with a billet
aluminum bowl stuffer. We then flow prep and clearance the assembly to race
specifications and finish it off with a proven Berkeley Droop Snoot.
