Don, I know you stated he probably will never exceed 3500 rpms, but he might change what he wants to do with it in the future, or even move the engine into a new build. I'm guessing there is a lot of money already in the engine at this point. $200 may be good insurance toward future performance and reliability. But heck I'm just guessing, it sounds cool when you say it's been balanced! I know Dan is a perfectionist, by how detailed and exacting his standards were on this build, I think this just continues in that level of quality that comes out from you guys!
