I remember a local Chrysler dealer having one of the winged birds back in '70. Couldn't give it away and eventually flogged it to a dealer west of Toronto. The ugly nose and extra price didn't appeal to too many. Look at the prices today. The COPO Chevelle that I bought new made a whole 260 rwhp at 5,000 rpm. Wow. A lean smog jetting in the carb and an advance curve that didn't come in fully until 5K rpm really killed the horsepower. Easily corrected IF you knew what to do. I did a lot of experimenting with jetting and the advance curve and before the first summer was done, I already had to put big tires on the back of the car to get some semblance of traction. Look at the prices today. A friend had a new L78 '69 L78 Chevy II. Brand new car and he took it right to the track. 15.1s was the best he could get out of it. Look at the prices today. These were the top Chevy engines and the lesser ones made even less power. The old saying, "The older we get, the faster we were." is true. The cars out there today would blow the old stuff right into the weeds. Sure, the old ones could make more power but didn't as they came from the factory. All said and done, we sold our Chevelles for good money, and bought our 13,300 mile 2005 Corvette in 2012. It does everything better than the old cars. Won't get the looks that they did, but that doesn't matter to us. I guess our egos are not that big. After six summers, we are still enjoying it.
