We just got these our next two sleeved blocks back from Darton. Woo Hoo. These are slated for Parm's and Andy's M3s. We will have them built in a few days to HPF specs. I'll take a few more pics once all the machining and assembly is done.
For those of you who haven't seen what we do to build these stout motors, here are a couple videos below the pics.
