    Very nice looking engine. If it runs half as well as it looks you will have a real performer.

      Rod,
      The thread suggests O-540 overhaul. Looks to be an injection spider on top of parallel valve cylinders. Some creativity going on here?

      And it’s looking great!

      Weighed the engine today. If the cheap chinese scale is to be believed it is 417#. That is with all accessories and the exhaust system installed. Added weight includes aux alternator at 6 pounds and 8# increase for the cold air induction system. Dual lightspeed ignition saves some firewall forward weight. My prop and spinner weigh 58# so firewall forward weight will be 475. I think Bob at one time said it should be no more than 450 but maybe that was just for the engine.
