If someone can say what he did wrong on the first two cams I would be very interested. He says he has proved his point but he won't clearly say just what that point is!
IMO, he's got the same issues as 64. The modern fast rate cams (meaning the ones designed for the .904 lifter) need everything perfect, or damn close. Lifter bore angles are never, I mean NEVER checked unless the engine is a decent budget deal and getting lifter bushings anyway.The old MP designs don't need things perfect. He did nothing wrong by most standards, but there was still something wrong with the first two setups. It happens.
