[ERA Chas]

Jon is honest, fair, meticulous and-technically brilliant. He's also a straight-forward nice man. I met Jon on several occasions and watched him run. He is candid and open about his engine-building, innovations and techniques. He's in a rare class of engine builders.

You don't mention your intended usage but I doubt this will fit into any Cobra. An FE has a 10.17" deck and this is taller.
If Jon builds it, it will make all the power you can afford.
