To think that this highly touted speedway lasted only ten years.

It's a pity that Ontario Motor Speedway doesn't exist anymore.

The Nascar races at this track in the seventies was like a ghost town. My buddies and me used go watch all the great ones of the seventies race at Ontario and we pretty much could sit wherever we wanted.

Best looking Indy cars ever!

I remember being at this inaugural race with my dad and brother...Thanks for this upload...Shouts from Mainz, Germany...

OMS was a great place

I was there.  In fact, I'm somewhere in the shot @13:28

These cars were so bad ass looking. 👍

I was there!

I've never seen a video of A.J. Foyt coming into the pits where he wasn't mad and throwing stuff.  It happened every single time.

was the Indy 500 of west coast

this track is designed very similar to ims, it's a shame that it's not around anymore

This is a really neat video.I had no idea the race was so close between Pollard and McElreath

I got to see the first stock car race at Ontario, up next to the camera spot on turn one.
Got in free as well.
Real estate values killed this track, it was more valuable as lots, than it was as a race track.

Sound is almost impossible to hear turned all the way up. Great video.

I was there. Turn 3 bleachers.

I gave this video post a Thumbs Up for availing it to the public.  But, whomever did the script for this film, I'll give a thumbs down for the lackluster details of the race.
I recall listening to this race on the radio, announced by Roy Storey.  This race was not televised.
The track conditions described on radio as being hot and windy, with problems of blowing dust on the track.  
I had to check with online sources to confirm my recollection of this race, where LeeRoy Yarbrough took a commanding lead at lap 187 when Al Unser dropped out of the race; only to have Yarbrough's victory snatched away at lap 191 with dropping out from a blown engine.  Gee!  You'd think that detail could have been written into the script.

The way I remember Roy Storey calling the race, I thought the finish between McElreath and Pollard was closer than what this film described; but online sources says the gap was two seconds.
I wonder if the written script for this film would not have suggested the pending doom for Al Unser's car if it had been using STP Oil Treatment?  I've checked with online detailed photos of Unser's car that season, and nowhere to be seen was an STP decal.  The engine used Catrol Motor Oil

Sometimes I think to myself everytime I watch some Ontario Motor Speedway video: how would be good if it still exist!


And more: I am a cartoonist and comic book creator and I am planning to create a comic about an Indy Racing League's alternative version where the Ontario Motor Speedway still exists and the IRL runs on it.

The Big-O, brother track to Indianapolis Motor Speedway and it's was ahead of it's time. Track management had failed the Big-O. I always going to like Ontario Motor Speedway over Auto Club, any day of the week...

A lane wider, more banked made the track faster than sister but more famed Indianapolis.

175,000 attendees. Phew.
