I have a friend that is selling a 427 side oiler. He claims it is a holman & moody engine. It has the tunnel port heads and intake and it is in runnign condition. What would something like this be worth. He has no documentation as far as being owned by Holman and Moody. I am thinking about buying it but i don't know what its worth. I came out of a 67 farilane drag car that he bought. Any information would be helpful.

Thanks
Jon
