anyways im still looking for 03-04 cobra.....next question is about the infamous engine tick on the cobra. is there a safe mileage for the cobra to have to say if the tick was gonna occur it would have done so by such and such miles. say for instance if no tick after 20,000 miles then safe to say it wont happen.......what was the precentage that 03-04 cobras had this issue. 2 out of 10 for example.......

 

the head tick is very common i cant say an exact percentage but id say 1 of 3 cobras have the head tick atleast from what i have seen come in and out of the shop its probly less then that but it is common and from what ive been told by several sources its more of an annoyance then a problem most the head tick cars dont experience any other problems such as power loss, oil burning etc. there is no "set" milage of when this can happen its a simple valve guide defect even the cars running "head cooling mods" still can eventually develop a head tick. the cooling mods work they help but they arent perfect if you run WOT long enough the mod can no longer keep up with the heat the super chargers put out, hence most cobras run an after market heat exchanger and possibly a vortech ice box.
