Answer1,3,7,2,6,5,4,8 is the firing order. The cylinders are numbered 1-4 from front to rear on the passenger's side and 5-8 from front to rear on the driver's side. THIS IS WRONG. THE CORRECT ORDER IS 1,5,4,2,6,3,7,8, COUNTERCLOCKWISE ROTATION. FIRING ORDER IS ALSO LOCATED ON THE INTAKE MANIFOLD, AT LEAST IT IS ON MY 97 F250 HD 7.5, THE OIL COMPANIES JUST LOVE US.
