Just traded some work for a cam/243 heads and I need help identifying a cam part number. It is an ls cam and it is supposed to be 593-593 and 247-248@.50. Just trying to verify the specs and the manufacture before I use it. I got it in a comp box with Thunder Racing on the shipping info but someone pulled the spec sheet off the box so I cant be sure it came from them. The part number on the back of the cam is 251031 and the number on the front of the cam is 01188061.

Thanks for any help.
