If you are sticking to 3rd Gen Camaros(No LT1 or LS1). In bone stock form the 5.0 Mustang wins everytime(305 or 350). The best power number for a 3rd Gen Camaro with a 350 is 245hp. Although this is more than 225. They Camaro is considerable heavier also 350 in those years only had autos behind them.
