Old style Leopard on a sprint track is usually around the same as a new style one. We run between 16,5-17k on most tracks on a MY09 Leopard and did about the same on the old ones. We bounce off the limiter a bit on the MY09 on a lot of tracks so revving it to 17k isn’t a big deal really. We usually do 10 hours between top ends. Don’t be afraid to rev to 17k on an old style Leopard. Your rebuild times and temps sound good and consistent with what we do.
TJ is right about everything except the part about our rebuild frequency. Top ends are closer to 5 hours and bottom ends 10.
