Problem with Harland Sharp rockers

Was a number of years ago, before I had my Challenger done and at the big races. Probably 2000 maybe? And Ron Mancini ain't no dummy. This is the same Ron Mancini who worked for Mopar.......Mancini racing (which he has nothing to do with any more) etc etc.

The thing is there is/was a problem with these. Being an engineer @ Chrysler and his family's racing history I have to give him the benefit of the doubt. But I was there. I had my fingers in his motor, and I saw the carnage with my own eyes. All I'm saying is if anyone wants to use these (or possibly any other like rockers) they need to see if they are made so the same thing could possibly happen to them under the proper circumstances
