I'm swapping to a TH400... (explored my other options- it seems to be my best one).
About a 4000-4400 stall appears to be the best match for my cam/rear.
How is this to drive around with? I don't mind looseness- but I'm concerned about keeping the heat down on longer trips (rare- but does happen)

Is anyone running this type of setup and how is it in terms of driving & what do you run for a cooler.
