They have a little defect from the factory where the engine ticks pretty loud check it out and it gets worse after your first oil change.... 40 grand for a car the motor should be quiet.

Nitrous 3Valve Mustang GT
yea but alot of new design motors has things like that, especially from ford, look at the new body f250 they put the motor so far back you had to remove the cab to work on anything on the backside of the motor, plus it kinda counters it with the fact that it runs 12s stock lol but it almost sounds like a rocker arm tapping lol or a lifter that isnt seated yet
