My upper block is a complete block. The lower is a little less than half, with the passenger side open. The rad on the passenger side is your cooling radiator. The one in the middle is the A/C radiator. I also ducted the remaining opening to the rad so the air that does get in must go through the cooling radiator. My fan does not come on very often since I did this version. But on long steep hills, the car will get hot enough to turn on the rad fan every time. The fan takes care of it. Brings me right down to normal operating temps.

Your stock t-stat begins to open in the 170s F. It is fully open by the 190s. My car will move between 194 and 199 when fully warm and driving on the freeway or something on a HOT day. If it goes as high at 206 generally the fan comes on right away.

Hope that's helpful to you...

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
