Roger,
I think you are making reasonable choices.  I'm pretty sure the IO3= 60 will run well on mogas at 8.5 compression, but I have no direct experien= ce.  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 wit= h the higher volatility of mogas.  To protect against that I have seve= ral suggestion regarding the fuel delivery system.  While it's probabl= y 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 electri= c pumps contain internal check valves, so you can simply T the outlets toge= ther - 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 automotiv= e "Bosch" pump would require a pressure regulator and a return to the tank = - not terrible, but I would like to avoid the complication.  No "auxil= liary pump" required, and if you want you could make the lines from the pum= ps to the gascolator in one length of stainless and joined ahead of the fir= ewall (I'm thinking about crashworthiness).  If you keep the header ta= nk, it's a little different story, but the same principle.  Next I wou= ld 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 Airflow= Performance 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&a= mp;C a look.  Not necessarily the lightest starter available, just the= best.

Good luck building!

Gents,

After year= s on the ground I'm starting put my LNC2 together,
this a/C was taken ap= art 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 confi= guration would be :
IO360 - 8.5:1 - setup for mogas. (I will check engin= es 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: Lightwe= ight type ?
Superior sump or other not ECI.
Locally powdercoated.... = Need to learn about specfic coating is needed ?
Please help me do the ri= ght choices.

Best regards
Roger Iverin
