Yes.
It's 253HP for the standard 300m with the 3.5 (all 1999-2004 3.5's were "high output" used in the 300m) It was 255 HP for the 300m Special (a sport tuned edition of the 300m).
A Chrysler 300M uses ATF+4 transmission fluid.

No - the largest wheel that can be safely installed on a Chrysler 300M 1998 - 2004 is a 20 inch wheel with tires that are 245 35 20. This will provide the same diameter size and roll rate as the standard 225 55 17.
A 2000 Chrysler 300m does not have a heater valve. The cabin temperature is controlled by airflow doors.
the top speed on my 300m special is 149mph
