Drove about 60 miles to that show. never been to that one in the past. Noticed Brutus was developing a slight miss. Good little show-parked in the shade. Lots of nice comments and questions. There were no "unfinished " or " project" class so I was in 60-70 modified. . Didn't expect it, but I did get a 2nd place trophy. Took a different route home and followed another old car that was having issues. got him into the next town. Brutus miss was getting progressively worse and making louder noises. I was sure that a cam lobe was wiping out. Still had good oil pressure. Stopped to get some oil and ZDDP. Started up and no oil pressure with louder noises. Called a friend to come get me and trailered to his shop. took off valve cover and I have never seen or heard of this before.--- The rocker shaft was broken in two where the hole for the rocker stand is drilled. Pushrods were down in the lifter galley, not bent , and no bent valves. lifter looked perfect. Big sigh of relief !!I will attempt to attach pics. Interior is not finished. ..................................MO
