==Overview==
Basics of ID'ing camshafts.

==Roller vs. flat tappet==
Telling one from the other is relatively easy. The roller cam will have much more rounded lobes, like the big end of an egg. A flat tappet cam will be much more pointed- similar to the small end of an egg.
Below is a hydraulic roller cam, the rounded lobes are readily appearant compared to the flat tappet cam to the right of it.

Often roller cams will be made of steel and will be shiny instead of a flat black color of a flat tappet cam caused by the wear treatment it is given.

==Warnings==
Roller cams cannot use flat tappet lifters, and vice versa. Besides the mechanical interference between a flat tappet and a roller cam lobe, the timing events will be skewed much to badly for this to work. A roller lifter on a flat tappet lobe would have very little duration, a flat tappet on a roller lobe would have way too much duration, even if it could work without mechanical interference.
