1968 Chevy Chevelle with a 454 Vs Toyota Supra?

My brother and i have been arguing this for several days now. in a drag race, quarter mile, which of these cars would win, i 1968 or 69 Chevrolet Chevelle vs. a Toyota Supra with a turbo. My dad and i say the Chevelle would win but my brother says a supra would win. ive seen the videos on youtube and the chevelle takes off ahead but the supra comes back and wins at the end but in the video the supra is a 1987 model and you cant tell what motor the chevelle has in it but i dont think its a 454.
