well for me anyway.

i have a cam for a single, just found it in my shop but the only markings on it are D222 stamped on the end of it.

i know it is a vtec cam just don't know what its out of, factory or aftermarket. and i haven't checked the lobes yet. i did do a side by side with a Z6 and its different, casting and all. any help will get a big ol' +2
