I'm willing to bet its a stock cam and really all you'll be getting is a set of headers and scrap. I can't tell from the sorry picture if it has headers or not. My opinion is if it has headers and they're useable you can get those out of the deal and pull w/e off of it and scrap it and get your $250 back. Now you might want to decide if you feel like going through all that or not. Or just str8 buying SDs and being done with it.
