Take a trip back in time when two of the three professional divisions had championships go down to the wire. This coverage appeared on NBC's Sportsworld, one of three sports variety shows which thrived before the advent of 24-hour sports cable television shows.

In Top Fuel, Shirley Muldowney had to fight off multiple drivers for a chance to win her second NHRA championship at the final race hosted by Ontario Motor Speedway.

The race coverage was broken down into two episodes with one focusing on Top Fuel and the other on Funny Car and Pro Stock. This second part of the video features the historic Pro Stock championship battle between Bob Glidden and the late Lee Shepherd. Ron Colson wins in his final Funny Car race.
