Not too much to update about. I'm supposed to be picking up a flywheel tonight and will hopefully get into the shop tomorrow night to lighten it. Then I can get my crank balanced with the flywheel and get to assembling the bottom end. Also, a friend of a friend might be powder coating the block for me (depending on what he says it will cost).
Today at lunch I measured up my cam gear and drew this. It shouldn't be too hard to make with a mill and a dividing head.
