PRICE IS FOR ONE CAM.  I have 10 of these 6-cylinder airboat cams. It will fit 470/520 sand cast rear alternator engine models. The part number for this cam is 535661. The picture is exactly what I'll ship you.  They were reconditioned like a certified cam, except they cleaned up a little below limits or have very minor pitting in non-critical areas.  No warranty or returns.  I will ship free to US Lower-48.
