I think the above statement concerning the limits of CIS is a typo. There are several CIS 930s on this board that go over 400HP to the rear wheels.

Other than tensioners there is not much you need to do externally to your engine to protect it at that level. If you decide to go into the engine there are many things that can be upgraded but may not need to if 400 is your goal.

Keep your A/R ratios in check, don't over-rev, change the oil regularly, and keep the normal operating temp of the engine under 220* and she should live a long life.
