Dual plug heads.
The tooling is ready to go for the first sample castings. The first 20, or so, go to Snyder. They will be available in iron also.

Re: Dual plug heads.
Wow, even after watching youtube videos to see how things are cast in metal it never ceases to amaze me. Keep up the good work Tod.

Re: Dual plug heads.
That amazing. I would love to see a picture of how they look once installed...even better, a video of one running.
Can I assume these are also high-compression? Ken

Re: Dual plug heads.
What ignition system changes are necessary to fire twice the amount of spark plugs?

If the aircraft is licenced as 'Experimental' by the FAA, redundant ignition may not be required (I'm not sure?), but it would be a good idea. |

Differing ways to accomplish same goal. As mentioned, some more modern distributors (Nissan, etc) are used. Another way Is to use Charlie Yapp front timing cover 'stock' looking 4 cyl distributor..up front, and to also use a mag or another 4 cyl dist up top. |

Re: Dual plug heads.
Very nice! My Dad built a Pietenpol back in the 60s (used a Continental A-65) I still have the plans and thought of building one someday. Car engines in aircraft scare me a bit but this would help.
