I wonder if those marine kinetics custom designs go thru testing like that, to find out which spring pressure is needed, and how stable the valvetrain is , and for how long.

I have called a big talked to Bob and I also called Cam Motion today. My cams are induction hardened 8660 billet steel premium grade cores. There are some better but many not as good. They are better than what the OEM's use for their hydraulic roller cams. After this discussion I am not worried about hardness issues or the cam specs. My boat runs great any it should for a long time.
After following this long thread and others it seems Tim's issues are more than a Bob M issue and more about the engine assembly and also putting all the right parts together to reach his goal. Maybe he should have had someone help with final assembly and checking all the parts to confirm they were all correct.

Really? Who said that? bob? Please tell me what's wrong with assembly? Every last detail was checked and logged I bet my build sheets have more info then 90% here....
So let's hear it... Bob tell you that? What did Bob say my issue is fault of? His crap cams? The wrong springs? What?
