This may not be relevant, but have you checked ignition? My Roush 427SR with MSD had oily plugs and ran really rich when new. Traced down the MSD distributor cap center electrode had broken off! Since then I've replaced the cap for a second time with the same problem. Fuel washdown probably caused some permanent damage, but the engine was off warranty by the time I found out the problem. Oil consumption is now 1200-1500 miles/ qt., compression is 170psi+, and the plugs are dry so I'm living with it.
