ARE ATK CRATE ENGINES GOOD?

[Mopar1979]

I have been researching different companies to try to find a 383 or 440 crate engine with at least 500HP. I have found a few, but i don twant to buy something thrown together. I want a balanced and blueprinted engine that is dyno tested and a good builder. Has anyone used ATK engines before? Do they build to your specs if special ordered? Any other companies out there that you would reccommend?

Thanks! They look like they build some pretty nice engines. The ATK look good from classic industries.
