WHITE SMOKE

Hello everyone I have a question about my 70 Challenger R/T
on the way to a car show my R/T started blowing a lot of white
smoke from the tail pipes and water also so I brought it back home
and was running real bad like trying to shut off luckily made it to me house
and was wondering what could be wrong with it before I tow it to a specialty
shop ? Any help will be much appreciated....Thanks in advance.
P.S... it has fuel injection.
