Mark,

Check the rod bearings for signs of abuse due to detonation and oiling issues. The mains will also give you some indication of oiling. That assumes you can get the thing shut off before contamination from the failures. In my experience these motors can develop oiling issues in cylinders 2 and 3 from high cornering loads. A baffled pan will help some, but I also run an accusump to make sure. 10 psi hot oil pressure is a little low, you should be able to maintain about 15-20 at idle while hot and 30-40 while at speed. Higher volume oil pumps are out there and a good idea, I also run an oil cooler. The big question is what are you oil temps?

The ARP rod bolts are definitely a good idea. Also, even with the 6k rev limiter make sure you aren't over reving on downshifts. Spinning beyond 6500 doesn't really do much in my 2.2, the 2.5 is even lower, but 5k seems a little low to use as a redline.
