John Walker's RV-10
If you are an RV-10 builder or flyer, you may want to check out John's RV-10 Facebook group at: https://www.facebook.com/groups/vansrv10/. This group has over 1000 members and is a great place to exchange information with other RV-10 owners.
As of November 2019, John has 330 hours on his EFII equipped RV-10. This plane has a 9:1 compression Barrett built O-540 providing approx 300 hp to the 3 blade MT prop. This plane is slated for an upgrade from the legacy EFII system to System32 electronics very soon.
Here is a great pic of John camping with his plane at the High Sierra Fly-In.

The ignition coil packs for the 540 sit nicely on a sub plate on top of the engine mount. The sub plate mount is included in all EFII 540 kits.
