Here's a picture of the Nova. It's not a good picture, but it's about the only one I have. It was actually blue but you can't tell by this picture!
I have no photos of the Chevelle I had, but it looked just like this- dark green, darker green vinyl top, white stripes on the hood and trunk. This one has the cowl induction hood, it's probably got the LS6 454. Mines had the 396/350, which was actually the 402 c.i. big block. And it was bored .030 over, had a Crane cam, 780 Holley, Edelbrock Tarantula intake...it was nice!
And this is actually Herb Ketter's picture, but my engine looked just like this- Tarantula intake, the carb. sat a little sideways on it, and I had the same air filter and the same Accel Super Coil ignition.That was about the only air filter option, or the hood wouldn't close. He also had a big block Chevelle, but I think he had a 427.
