I will see if I can't get Ken Kershaw to chime in. He is the head Tech Inspector for PDRA. Pretty sure he's on top of the competition over there.When’s the last time PDRA had one of those monsters apart? When is the last time they P&G’d one? I think Douglas may be onto something.....
Not to mention I don't think any of the engine builders Musi, Buck, Leonard, Fulton etc would put their integrity on the line with an illegal engine.
