I had a convertible Firebird eons ago. After killing the rings with the first Vortech SC, had a balanced/blueprinted bored out block put in its place. Only 600Hp at the wheels, but it felt like the Hand of God pushing the car whenever I got into it. But I had to replace almost all the suspension, the rear end, added roll cage, etc. just to make it handle well. Miss her (sniffle).
