Roger,
I think you are making reasonable choices. I'm pretty sure the IO360 will run well on mogas at 8.5 compression, but I have no direct experience. I've heard good things about the P-mag and that's the one I would pick. What about using 2 E-mags?
The concern I have is with the higher volatility of mogas. To protect against that I have several suggestion regarding the fuel delivery system. While it's probably not practical to put an electric pump inside the fuel tanks, I would put an electric pump as close as possible to each fuel tank. Most electric pumps contain internal check valves, so you can simply T the outlets together - whichever pump is on is the tank you are feeding from. However, I'm afraid I don't have a good suggestion as to the best pump to
pick that will supply the required 12 psi or so. A typical automotive "Bosch" pump would require a pressure regulator and a return to the tank - not terrible, but I would like to avoid the complication. No "auxilliary pump" required, and if you want you could make the lines from the pumps to the gascolator in one length of stainless and joined ahead of the firewall (I'm thinking about crashworthiness). If you keep the header tank, it's a little different story, but the same principle. Next I would make every attempt to keep the fuel cool on its way to the engine. The gascolator should be mounted as low as possible ahead of the firewall and in an insulated box. The standard mechanical fuel pump, which is now the "backup," should be boxed-in and positively cooled. The whole idea is to keep the fuel under pressure and cool. I know the AirflowPerformance system is available with a return line, but I would
recommend using the Precision Airmotive Experimental unit. Maybe it's just because I've worked with those guys for many years and think highly of them. You can add the Airflowperformance return line to it as well.
As for the electrical system, give B&C a look. Not necessarily the lightest starter available, just the best.
Good luck building!

Gents,
After years on the ground I'm starting put my LNC2 together,
this a/C was taken apart and robbet by HighSpeed Composites.
I will need a lot of advices and one big issue is the engine
configuration.
This is what I have bought so far:
ECI kit engine: (will build engine myself)
(IO) - 360 8.5:1 pistons. (constant speed)
No harness, fuel injection,
mags, starter/alt.
This is what I think sounds like an suited configuration would be :
IO360 - 8.5:1 - setup for mogas. (I will check engines components, not
sure about tanks wil take it)
Fuel injection: http://www.airflowperformance.com/html/site_html.html
Mags: One p-mag and one slick.
Alternators: Lightweight type ?
Starter: Lightweight type ?
Superior sump or other not ECI.
Locally powdercoated.... Need to learn about specfic coating is needed ?
Please help me do the right choices.
Best regards
Roger Iverin
