i have a 93 pro star ford 351 H.O engine with holley carb and electronic ignition,can anyone tell me the firing order? manual says 13726548 but won't fire up? tried it also 180' and no joy?
also spoke to mastercraft dealer and they said their is another firing order for that engine 15426378 is this right or is there any others?
