Uhhh...If its a 350 2 barrel it should get decent gas milage 20+ on the highway. Most 350's of this era only made like 150-165 hp unless it is a "special" version with a different cam. also tons of low end torque. My friend has a 77 trans am with the pontiac 400 and gets 25 on the high way, the 400 in 77 made 180hp and something like 300+ f/lb of torque. You may want to check the carb and tune it. The quadrajets are efficent for a 4 barrel carb and you could pick up a carb and manifold for a small block chevy for real cheap. Also want transmission is in it? If its one of those 2 speed POS's then that is probably the cause of the more milage. Yank it out and put a Tubo 350 or 400 in it, and you'll see an improvement, or better yet put a 4-speed muncie in it.
