440 source engine packages

Big strokers, 500 horsepower isn't hard to get from a built 440. That's like 1.13 horsepower per cubic inch. That should be easily done with a 440

Hpw many have you personally built and/or dyno'd? What people like to say on the internet and reality are often not in the same space. I say that from direct experience on the subject at hand.
