This is going to take time to finish, as I've started it before everything is ready.
This appears to be one of the first designs. I bought this about eight months ago and it sat in the garage ever since. One day I noticed it was rusting, so I soaked it in oil.
When I purchased it, Ron at Black Magic told me he was getting this piston ready. So it appears I bought it before all the need work was taken care of.
They needed to be bolted on to the block, as I was torquing down the pump heads bolts I noticed the bolts were going in too tight or not all the way. I pulled the pump head (the seal for the pump head stayed stuck in the block. Hmm... not a real problem).
