I know I dont own a L and have not been a member that long... But if you didnt know that about your truck something tells me you shouldnt be looking for cams. Sorry.
yea its a valid question but he shouldnt be looking for cams if he dosent know weather the are sohc or dohc........does he have a built motor to support cams?
if your going cams as your first mod your going to smack yourself later. cams are good after you done everything but them. buy a lower pulley and a good dyno tune.
