When in fact most cases the exact opposite is true. They will generally make more power down low in the driving range than a stock engine. The biggest difference is that "peak" power occurs at a higher rpm point. However, that doesn't mean it makes less power at 3000 rpm or less than a stock engine does.

Paul has shown this time and again pulling his "built" engines down to 2000 rpm on the dyno. They might make peak torque at a higher 4000 rpm vs 3400 on a stock engine, but it still makes more at 3400 than the stock engine does and at every point below that as well.

But, guys that never run their engines on a dyno wouldn't know that, they just know what misinformation they've read on the internet.

I always thought is was common knowledge that in our world, Pontiac engines, particularity 455s that are in some form real 455s or stokers that make up most of the performance builds make power down low no matter what.
You can not kill the low end grunt of a 455 if you tried to. They have a lot of "suck" to them. Essentially the same reason you can run a bigger carb and not drown the engine out vs other brands.
