The “skunk stripe” upholstery, labeled as “cheerful” in the Nova sales brochure, is a Nova trait and is, as expected, in perfect condition. Inside is like outside, what’s not to like? Novas of this era are plainly attired with simple, functional interiors. And found here on Steve’s Nova Site is a thread about this Nova, written by Jack Duer in 2010. Gold Certificate winner and featured in multiple magazines“. ![]() The seller adds, “ Concours rotisserie restoration by Jack Duer with amazing results including the highest scoring restored Nova in the history of “National Nostalgic Nova. And once again, we find a set of authentic Chevrolet mag-style wheel covers. This Chevy is resplendent in its code K finish, Emerald Turquoise Metallic paint. The seller claims 4,860 hours were invested in this Nova’s restoration. So, what can you say about the exterior? Nothing really as it’s perfect. No word as to how this four-speed manual-equipped $225K car motivates, perhaps at that price point it can’t actually be driven. The compression ratio, valve size, carburetor, cam specs, and ignition total advance are the same for both versions but the Corvette’s engine is rated at 5800 RPM, while the Nova/Chevelle’s variant is recorded at 5600 RPM. As to what’s responsible for the difference between the Corvette’s 350 HP rating and the Nova/Chevelle’s 325 rating it appears to be how it’s measured. The engine’s casting date is May 19th at the Flint foundry so it does line up with a June build date and its sequence number matches that of the car. Here’s where the debate starts, this Nova is claimed to have a June build date though there is no image of the trim tag. I have seen numerous ’67 Chevelles with this desirable engine as well as 1968 Novas and Chevelles where it remained an option. That being the case, they stopped the availability of the engine in the Nova but allowed it to continue on in the Chevelle while the regular 350 HP version remained a Corvette option. ![]() got nervous and jerky over the thought that the L79 Nova would rob sales from the brand new Camaro. Supposedly, the six L79 Novas were built very early in the model year, likely in September of ’66, before Chevrolet’s Marketing Dept. For ’67, Chevrolet introduced an alternate version of the L79, rated at 325 gross HP for use in both the Nova and the Chevelle. In 1966, it moved from the Chevelle to the newly restyled Nova and it was a huge hit! Lots of high-winding horsepower in a very lightweight package. Chevrolet introduced their L79 engine in 1965, it was a 350 gross HP, 327 CI V8 and available in the Corvette and Chevelle. OK, so here’s what I have learned over the years. It is located in Portland, Oregon and is available, here on eBay for a BIN price of $225,000 (double gulp!). This spectacular Nova is one for close study. How rare? It’s universally agreed that there were only six produced out of a total of 106K 1967 Novas, but exactly when and why is at the center of the debate. For your review, is a 1967 Chevrolet Nova SS, equipped with a rare L79, 327 CI engine. Air passing over the radiator fins makes it happen.OK, let the debate begin! But first, let’s set the background. Once the heated coolant reaches the radiator, it needs to dissipate immediately. ![]() One other heat contributor is airflow, or, to be more precise, the lack of it. If you factor in temperature and humidity, it becomes easy to see how the cooling system becomes overloaded. At 5,000 feet, the boiling point is 201 degrees F, and at 10,000 feet it's 193 degrees F. The water in the radiator will begin to boil much sooner. This makes the engine generate all kinds of extra heat as it's working harder to do less. This means your engine is trying to do the same with less than half the available horsepower it originally had at sea level. Your engine's compression pressure is now 120 pounds per square inch after compression. Then, you drove up Pike's Peak to 14,000 feet above sea level. The compression pressure is now 194 pounds per square inch after ignition. But you just drove to Denver, Colorado, which is 5,280 feet above sea level. At sea level, your stock engine has a compression pressure of 256 pounds per square inch after ignition (with 8.0:1 compression ratio). The density of the surrounding air affects the amount of horsepower potentially available. The engine itself is also affected by atmospheric pressure.
