The tail shaft is larger on a th400 and the case is bulkier. and the pan gasket is not square with the corner cut off like a 350

No I don't, Most of your cooling will be done by a trans cooler when running. Fins are better than no fins, and cast aluminum isn't as good at transfering heat as a sheet metal aluminum is. Steel is just fine as well. I focus on the cooler for cooling. The larger the pan the greater the heat sink. The larger the cooler the better the cooling ability.

the deeper pan will hold more fluid so that alone will help with the heat.

I use the heavy cast aluminum pan on my glide ..it helps to stiffen up the case..at least I think so.

Well, the more oil that you have in the system, the more heat that it will take to raise the temp.
