Simple answer to this question..........POWER is directly rated to air flow.......flow more air, make more power. Now the question to the question, is how much power you want to make.

If your goal is 700hp or less, either can easily do it, with the smallblock in this range only required to be slightly more exotic to achieve these numbers. And in a weight for weight car, the small motor should be quicker because of lighter engine.

If 800hp is what you want, both can still easily do it, but the big block gets more costly and the smallblock gets REALLY costly.

If 900 is your goal, this is big block land......... NOT saying a smallblock won't make 900, it will. But at that level the 900hp small motor will cost WAY more than the 900hp big block and be less reliable.

If you want a good bit over 900hp, this is big block land......PERIOD
