I expect to run Mobil 1 5w30 year round because it gets hot in Florida and I see 7 grand on the tach regularly on the street. Do I need more mods than that to keep this engine together on the track?

I'll reply here regardless. I have a pretty special oil cooler setup. People would consider it oversized but I can manually adjust the flow after the thermostat.
Based on specs published in the service manual, the important number to watch for is the target maximum oil pressure of around 70-75 PSI. 0W20 is fine for me if I keep it under 185 F. I haven't experimented with other viscosities because I like the fuel efficiency benefit.
A couple of the local guys have beaten the piss out of their engines with no oil cooler and are still running strong. I think engine longevity is mostly a numbers game with respect to build quality and manufacturing tolerances.
I suggest getting the pressure gauge first so you can watch it and make informed choices. For instance, you will notice how high the pressure is when it's cold. It's a struggle for me to keep it under 120 PSI for the first few minutes. 140 PSI is where it bypasses to protect gasket and o-ring seals, and the pump. Keep that in mind as you play with viscosity.
