Okay taking a looooong shot here...
You're running with a doghouse fan shroud on a single-port engine. I'm assuming that Mr. Bookwus had upgraded to the doghouse cooler because of the commonly-accepted wisdom that it's the better system.
But... What if the doghouse fan shroud isn't a good match for the single port upper tins in terms of air pressure development compared to the original fan shroud? Or if the single-port upper tins lack some airflow-directing vanes that the dual-port tins incorporate? It probably doesn't need asking, but is the fan shroud a nice snug fit to the upper tins? Is it an aftermarket shroud?
I'm just making a WAG here: it's been a lot of years since I've peeked into a type 1 fan shroud.
