Thanks guys, for your comments. Jack, as far as scale, I can only go by what the box stated. However, the 13-inch Corvair tires l sourced from Modelhaus Tires look spot on and the Corvair engine from another 1/24 kit, looks to be just the right size. I had doubts about scale also but, I think it's a little too big to be 1/32.
Jesse, Bill: Thanks for the photos. As you can see, there is a whole lot of steel chassis surrounding, (and hiding), the engine. I wanted to avoid that so, watch for later photos and see what you think. Also, that is not the original engine as it is turbocharged. Apparently, this show car had a very busy life and a few engines. I have several B&W photos of the car in 1963 at Watkins Glen and the '63 Turin Salon in Italy where the first motor was a stock unit with a single, center mounted carb, and air cleaner. I also had no desire to replicate that strange exhaust system! I'll send a photo of the underside.
