Joe, I never got to see a drag race at Ontario, but I did see some Indy car time trials on a visit there in the mid 70's. That facility was huge. The video you found showed how the staging lanes and even the burnout area actually started on one of the curves of the race track. Pretty wild. Here's a good question...does anybody recall when they started raising the body on Funny Cars after backing up from the burnout? I seem to recall that was never done back then, and this footage seems to bare that out.
