350 Chevy operating temp

[Bulldog]

OK, now I feel a little dumb. The first time I blocked off the radiator I only loosened the fan shroud and inserted cardboard. Upon closer inspection, to get the cardboard between the radiator hold downs; I only had covered 70% to 80% of the radiator. Before I changed out the fan, I decided to cover 100% of the radiator. I removed the radiator hold downs and leaned the radiator and shroud back allowing be full access. I used some reflective foil insulation to cover the entire radiator. After a little test drive, the engine was running at 210* (insturment cluster guage) and I even saw 215* at one point. The cab heat is decent now considering it's -30* outside.
