as far as I know the cam is stock. Oh yeah i have a HEI form a 75 250 installed. The head is a newer head with "small" spark plugs (5/8" socket) I have not looked up the casting number yet. The block may be a 250, will not know until I get the head off for the lump port, the casting number says it is a pre 67(no vin number in block)230 or 250, guessing that it is a 230. I have no idea on the compression, I just know the thing runs great!
Thanks
