Paul & Tracy,
I have built a mockup of my RV-4 firewall (I received the fuselage
kit last week, but I built the mockup in June) and I am going to
use a layout similar to what Paul shows here.  I think that the
P-Port engine is going to require a cowl bumb, so suddenly making
the bump a little bigger and on both sides is not as
objectionalble. I am planning on building a cowl like Allen Tolle
used on his RV-4.  Mike Wills is also going to build a cowling
like Allen's.
Paul, BTW how are you planning to x-brace the motor mount when you
use the redrive plate as the main mounting point?

I am going squeeze diagonal tubes in somehow but they don't really have
to meet at the firewall. The way Mike welded them to the top of
the landing gear legs is a very good way to do it.

Come to look at it if you use the stock starter location it is only a minor 
modification to Tracy plate. Cut off the bottom and notch the spot where
the starter goes with a band saw and you are done. All you then need is a
couple of longer 10 mmm bolts.
