Hi, first time post. I currently have a 56 chevy 4 door belair wagon and the current 290 small back engine is finally getting to tired to pull the car. I am at a cross roads for doing an engine swap. I don't care about brand or # of cylinders, but I am trying to make 400-500 hp/torque and get 30 city-freeway driving normally. So far I have been looking into modern cars that have similar or heavier weight mostly Audi and Mercedes, but they are expensive. Does anyone have any recommendations from other brands or is this my only option.
