Well, the engine mounted fan was actually worse than the two efan options :(
About 7 degrees hotter everywhere on the rad...
So I'm gonna try this next week.

Engine fan pulling, efan pushing
A 440 with high compression, he was having the same problem, so he went with one pulling through a very nice looking shroud with one pushing and problem solved.
Still don't know why it ran fine for nearly an hour on the day we were test driving, and now that it was "flushed" it's garbage :(
I'll get the timing adjusted as well.
The joys of driving a former drag car that was made "streetable"
