I just got of the phone with Crane cam. I have a new lifter on its way! He thinks maybe the lack of maintenance is why it came loose. It runs to good to change a bunch of stuff, so I am going to replace that lifter and adjust all the valve and see if thinks stay together. Remember it has not had a valve cover off since 2001 or 02 and always fired right up and will run low 12 seconds and I shifts at 6500 rpm when I raced it. Thanks for all the help!
