All testing is being done with the hood up in the driveway. I have a rubber seal between the hood and body. For what its worth, once I managed to get the car to idle at 195F using the second pusher fan in the nose, I observed the following IR temp readings with my new gun:

- Intake manifold surface by the temp bung 180-185F
- Valve covers on header side 165F
- Carb body 135F
- Expansion tank surface 200F

This is in the hot sun with oil temp level at 215-220F.
