I recently bought a set of Comp XE268H camshafts. I just got to see them today, been at school since I bought them. Well, each one looks the same; the bolt hole in the end appears to be the same, but I can't tell for sure. I'm pretty sure that they are actually different though. One cam has "XE268H" and "UH9246" ground into it. The other has "XE278AH" and "UH9066" ground into it.
Now I know that those are two entirely different camshaft grind numbers. But what I want to know is do they come from Comp with those numbers ground into the camshaft? Or did someone do that after they were bought? Only reason I question is because I thought the camshaft bolts were different sizes, and these appear to be the same.
I'm about 99% positive they are two different cams. On the 268H cam, the max diameter of one of the lobes was 2.17 inches; the max on the 278AH cam was 2.20 inches. That basically proves to me that they are different, but I just wanted confirmation. Thanks.
