    I got a 855 cummin been trying to figure out if it a big cam 4 or is a small cam? Was told by someone just looking at the motor from a glance that it’s a small cam. But from what I understand a small cam was built before the big cam came out. Could someone inform me cause tired of trying to find info on the net. I added the engine tag it says ntc-315

    315 is a Big Cam engine if the tag is correct. Post a pic of the cam follower boxes on the left side above the starter.
