Quote: If your goal is more "snap", I'd replace the cam and valve springs, put a good ignition system on it, and either get it properly tuned, or learn to tune it. You can get beyond 400hp very easilly without gtting into anything beyond the cam, and that includes the factory intake and carb. If you want to rebuild it properly for performance, it will cost somewhere between $4-5K depending on parts choices. But from what you say you have, and say you want, you have 95% of what you need. Work with a good knowledgable builder, do what is needed to get your result, and don't break the $1200 mark.
