It is the original OEM pulley size. These temperature changes haven't been happening with the exact same setup in the past so I suspect something failing.

I guess the simplest thing to do is change thermostat to high flow unit. Any recommendations on model.?
Car also has the OEM Pontiac intake manifold.
