Chevies had problems with transmission modulators that were vacuum operated going bad and sucking trans fluid into the intake.......I know trans fluid burns white and thick. Can't think of any way trans fluid would get into the engine on a Mopar though. A bad valley pan gasket on B/RB blocks can cause oil to get sucked into the intake runners but then the engine wouldn't run like a champ. If it were steam and coolant is coming through a mild head gasket leak you would likely find the plugs on those cylinders very clean but unless you do a leak-down test you might not know you've got a problem. A compression test might not show a minor leak. Try running the car with the rad cap off to reduce the pressure from the cooling system..... Does the smoke appear when the car is cold? Have you checked the valve guides? Seems to me white smoke has to be steam or trans fluid. Just my two cents.
