My plans, your thoughts

The newer 09 and up 5.7 has the eagle heads, which are the larger ports like the 6.1 engines, the 6.1 intake will bolt right up to the newer heads if you wanted to. They are 390 hp stock and cams are available as well as an ECM to put in your muslce car. 35hp less than the 6.1 for half the cost used generally.
