If anyone has a list of the different letters stamped on different cams I could really use it. But if not I'm specifically looking for the letters stamped on a CTR intake cam and a first gen B16 (AUTO) cam.

 

That's a B16 auto INTAKE cam.

to tell if its a ctr cam just look at the distributor side and look to see if there are any rings in on that end of the camshaft. you will know them if you see them they are pretty deep. thats the best way to tell if you have ctr cams. do a search i know people have pictures of the difference between ctr and b16 cams

 

two ridges/groves on the end, and on mine theres a H stamped beside the second set of lobes, maybe that just stands for honda, i'm not really sure, but theres nothing else stamped anywhere on them
