I am looking for a cross drilled camshaft for a 292 p/u. My truck is a 63 which I guess they started using the cross drilled cams again. I already have the cross drilled cam bearings in the block. Mine cam has some pretty major pitting on the edges of the lobes.  I don't know if the cross drilled camshaft lobes are the same on the 55,56 maybe you guys can give me some info on that. you can email me at Raymondac23@yahoo.com if you have one.
