Regarding the con rod failures of the 77, I seem to remember reading Col Th's articles in RCM mentioning a lack of lubrication. I believe he used sandpaper wrapped around a suitable sized dowel to increase the ID of the end just a tiny bit. Any one else remember the dimensions? I'm a pattern flier, so I never ran DF's, just that I happened to remember the article. Hope this jogs someone's memory so they can help out.

Cheers,
Ken
