its a 400... and i only get about 8mpg towing the enclosed trailer pictured. i'm going to swap carbs to an edelbrock carb i have and see if that improves any.
i have a rear main seal leak, and a friend of mine has a 454 he offered me for cheap, so i'm looking at probably buying that motor from him and swapping it in... if i can find a 5 speed at that time i may do that as well.
