Simplyconnectid, I agree with you on the smoothness of the inline engine. It has been a long time since I built an engine. In my younger years, eons ago, I did that for a living. But it was as you said, I had to do it on a schedule. Like "HURRY UP". I have overhauled my own back then, but never a complete rebuild such as this. I am excited to get to do this. Where on the pistons, and with what, do you remove material to balance them? When you say c.c. your heads, what exactly are you refering to? I really enjoy talking to you and Dave Corbin. Will continue to pick your brains as long as you will let me. Thanks Ben
