WOuld anyone know the cam part number for a 03 lightning?
WHen I bought my lightning I was told it had crower cam's in it. I've got the engine tore down now and the cam's aren't what they were supposed to be I think they are stock.
The easiest way to tell the difference between stock and aftermarket cams would be to take a look at the cam timing gears. Most if not all the aftermarket cams have timing gears that bolt on while the stock cam gears are pressed on (no bolt holding the cam gear to the cam. I think the stock cam gears are also gun drilled as well though you cant see through them from one end to the other.
