i have a 1991 5.0 mustang and i am rebuilding it and when i was taking it apart i saw that it has a roller cam. everything else on the car is stock i just want to know if they came with the roller cam or if somebody has already been there.
The stock cam is a roller grind in all EFI 5.0 Mustangs. Not sure what year they started the roller off hand, but I know it was back when they were still coming stock with carbs.
