I bought a v8 5.0 95 gt mustang and it has a aftermarket cam and I can’t find out what one it is . The engine timing is retarded like 80 degrees, wayyy too much, miss firing like crazy. I need to know if I fix the engine timing, will it ruin the engine or affect the camshafts negatively. Considering I don’t know what can it is. If anyone know I would really appreciate it.
