differences ?
 

besides the EGR ... is there any differences between the federal and the cali emissions trucks? just wondering

Im not sure about that. never scene a california em. truck. I have looked a a small pic. It looked like a cluster. Ill bump so maybe someone can help you out:c:

im not sure but i was looking in a dodge manual and i think the timing was set different, mabey smaller pump, but other than that the internals of the motor and pump shuld be the same
