What cam do I have?
 

Is there anyway to tell what cam I have short of taking it out? I really need to figure this one out. The car rides pretty smooth. Before the car is warmed up the idle lopes like crazy, but after it is warmed up it only lopes a little.

The guy I bought the car from said it was an x-cam(I dont no if this it true) He is a great mechanic so he should know what he is talking about.
