Hey that's my Bob cam! Now the million dollar question is if I should fire it up and run it? Or pull it? I think I know the answer to this one. The thing that frustrates me the most is... last year when I started my project build several people referred me to him. I've built several engines over the years and never once did I run in to so many issues.

The RPM expected to run with those cams is 5800. I stressed many times on the phone with MK reliability was most important to me. Like most I don't have an open check book. The exhaust I am going to run is Gil dry.

Honestly,,,, just take a look at tims and others. I wouldn't take a chance over 800.00 worth of cams. Next thing you'll be getting your cranks ground and new bearings and who knows what all else.

I only have a single. The thing that sucks is I just put it in the boat and almost have it ready to fire. It's been a big project. I did a complete bilge makeover, the engine, full hydraulic steering, K planes, and a new drive. I really wanted to get it up and running and play around with this new Holley HP EFI system. Oh well, I guess it's it's just another speed bump in the never ending project lol!
