OVERHEATING
Based on the Bay Pic from post #49, I say Awesome looking and all looks in order. Kudos!
You either have a cheap T-stat or a nice looking radiator in appearance that is not functioning.
Also Based on that pic, I assume you have the hood seal installed as the attention to detail is great!
Spend the cash for a high flow Stat from Milodon, and or send that radiator to GlenRay for a full rebuild! I would also recommend a high flow pump from flowcooler.
There is no other good reason for your awesome car to be overheating at cruise. JMO!
