A 2003 Mustand SVT Cobra Terminator had stock 390 hp, 390 ft lbs of torque, and 8 PSI of boost. Yours has apparently been worked on to increase output 54% over stock, to your claimed 600HP. WHY ON EARTH ARE YOU RUNNING 5W20!!?? If there ever was an incorrect oil for its application, THIS IS IT!
Get some 0W40 in that thing and save those bearings. The newer Trac pack and BOSS 302 cars even recommend 5W30 and yours has far more horsepower.
