Sold my duster for this......

was going to the track last friday night for test and tune. I figured I better run the valve lash before pounding on her too hard. took the valve cover off the driver side and found the mess in the pic. the nut and top half of the adjuster was laying in the top of the head. the bottom half of the adjuster was still threaded into the rocker arm but had started to back out. found that mess just in time, and still got lucky that the nut and top half didn't fall into the oil return of the head.
I have only run the car up to around 5800 rpm a few times on the street. the shift light is set at 6200. the old guy had told me before I left that he had been setting the valves at .012'' lash! I didn't say anything, but I knew that was way to tight. I contacted the engine builder for his take and he said .018''.
the old guy had also said the last time he ran the car that he made one pass and the car nosed over on him before the finish line. I think we may know why, now.
anyway, got another 4 pack of adjusters coming and we are gonna get everything set at .018 where it should be. should pick up some bottom end after the adjustment as well.
