So I found a car on craigslist that says it has a xp cam and then 1.9 rr but he says he is not sure of the exact length of them because he swapped them over. (car was built, then sold, blew then motor, then went to him where he swapped everything over to this block and doesn't remember and just said 1.9's). Im positive it is the xp cam, but not sure size on rr so who can verify this? Thank you
