Iron block LQ9 bored to a 408 if you want to use n2o or some other power adder. You can go up to 418 if your not hitting it with any juice. The longer stroke for the 418 makes more torque, but not good for anything other than N/A. Both these will produce great RWHP #'s plus high torque #'s, compared to building up the 346.
Plus, to get 470 RWHP out of the 346, it will not be the best "street" car. To get that power out of the 408+, you don't even need a big cam. You can keep it a lot more "driver friendly" with the bigger cubes.
