Snakehunter we have a Shelby engine almost done and coming for install in a new Shelby roller. It looks like less than 3 weeks. I would bet that motor survived even the freezes, if they can handle combustion forces they can handle a little freeze I bet. You'll find out soon enough. I was thinking pop a rivet out of every tube in the frame and put the chainsaw (environmentally friendly and sticky) bar
oil to the inside of each tube. You'll figure it out and have the right approach, to document it well and keep it all above board.
