looks like you are having problems getting a response? Here I go, I would look for a second generation engine with a P Pump (inline). From there you are going to send a lot of money because you will need to have the rotating assembly blanced for the highest sustained RPM you are going to run, you said 5000 that is a lot. You will need a main girdle, and I would decompress it to 15 or 15.5 to 1 compression raito to help breath at higher RPM. In order to get enough fuel to make 800 ft lbs at 5K you will need a custom pump and injector. Don't forget to fire ring the head and install studs, 80 lbs springs, Ti keepers, you will need a custom intake, a little water, and turbo set for that, well I am not sure maybe a S256 with a 50mm external wastegate over a S464. That should put a hole in your pocket.
