Chuck - Excellent as usual. With the exception of the 3/8" line running from the radiator to the expansion tank, that is exactly how I've done all the Cobras I've done and it has worked great.
I have somewhat different plans for my Forty as I outline in the Cooling section on my website - but the basic concept is still the same.. I'll post more later on my own build thread if I can ever figure out how to capture photos from my website to be used here..
I just want to also thank you on behalf of many who will get great value from your build log.
While you and Ryan may not be automotive engineers, you've proven that with determination and a logical approach you can accomplish nearly anything.
My Grandfather and Father taught me that as well.. I'm still working on it..
Kudos guys...
