Neat!  I remember reading about Flamborough and Cayuga in Wheelspin News, and seeing pics of the cars there.  I always thought they must have been the coolest tracks to go to!  Being in the Martimes, we didn't really get much coverage in Wheelspin, though.  I still read it from cover to cover each time I got one (everybody received a copy upon entrance to the track IIRC).

Atlantic Speedway was a 1/2 mile oval, with relatively long straights, so you could really hear the engines winding out as they hit the back half of the straight.  The cars could hit some decent speeds, but that also led to some fairly substantial wrecks.  IIRC, most of the other tracks in my area were 1/4 to 1/3 mile, which were mostly turns with short straights.

Another tidbit of info was that they had a street tire rule to keep costs down as the endless competition to have bigger and stickier rubber than your competitors was driving costs up, so you will notice the Road Hugger belted tires on the car.  That's what they raced with as a cost control method.  Drawing from a smaller population, they had to keep costs down to get enough cars to show up each week.

Also, at this track there were two classes initially: Modified and Sportsman.  The Modifieds were full bodied cars and didn't look like what they were calling modifieds elsewhere, which were typically open wheel cars with a half coupe or compact body on the chassis.  I don't have a breakdown of the rules, but the Modifieds were faster, obviously.  Outwardly they tended to have larger tires but I don't have an intimate knowledge of the differences.  Later a mini-stock class was added, which at the time was Datsuns, Toyotas, Pintos, etc.  I don't recall seeing any Vegas in the class - maybe due to the engine issues they were having?

Yeah, lol on the vinyl top.  Ya have to remember in 1974 those half vinyl tops were the latest and greatest thing, even if they look a little out of place on a Camaro.   Gotta keep the sponsor happy!
