360 Advice Needed - Autocross / Street Engine Build

SOLVED! The fan was on backwards... :(

I mounted the shroud tonight, and the problem became very obvious. A ton of hot air blowing out from the grill!
With the shroud in place it moves a lot more air, and I could tell that the fan was pushing not pulling.

For some reason all this time when I've been looking at the engine, I always thought it spun clockwise when sitting in the drivers seat.
I noticed the writing on the fan belt going around, and then looked at the fan blades. I messed up big time on this one.

So a little history, this clutch and fan assembly was swapped on with my old 360, which cracked the block then overheated. (I now suspect it was the other way around!)
I guess a lot of this work / expense could have been avoided by looking at the fan rotation the right way... :BangHead:

At least it should now be a pretty stout build! Just hopefully didn't miss anything else like that.
