I actually have no idea about the engine size. This Squareback was originally from Van Nuys, CA. I found it in a parking lot at San Diego State University in 1979. My son Evan and I drive it around town and think through its fuel injection's many neuroses. I've worked on it for so long that I refuse to let it die. The car's main job is to appear in the town's biannual 4th of July parade.
