Looking for a Super 6 setup in CA

ALL Station Wagon Aspen/Volare were 2bbl.

Not true. When I was a kid, our family station wagon was a '76 Aspen with a 1bbl slant, bought new at the local dealership. I eventually inherited the car when I was old enough to drive. That was my first, and worst, slant six experience ever. One of the slowest slugs I've ever driven.

Never figured out how my Dad could've actually BOUGHT that car after a test drive...
