A few things are moving forward, not as fast as I'd like. The crank and rods are at the machine shop, should get them back in a week or 2. The intake and exhaust runners are trying to run into each other, so I've got some work ahead of me there. Lots of test fitting then tearing it all apart.

This is what 9 hours of tire grinding looks like, one more to go. This is also only about half of what needs to be done, we should take the lug height down from the original 1 3/4 to about 5/8".
