Here is the update. Not sure how much you have seen mentioned here on the forum, but the day before Thanksgiving I just got the first batch of prototypes that looked good. In fact I've already delivered a couple sets to some people on the list. After I confirmed that the valve covers machined properly I put my production order into the foundry at the beginning of December. The first date I got was delivery on January 22. They missed that date, though, and are now saying that the valve cover castings will be ready by February 15. That is where we are currently at.
Assuming I can get the valve covers on the 15th, it will take me some time to go through the first machining operations before I can start delivering. So, I am figuring early March when I can start shipping more of them.
Once I have the production batch of castings here, everyone on my list will get an email showing the options available for the valve covers, and pricing. So, watch for that email, sometime in the next couple weeks - Jay
