I was the first to say, that there's nothing bad about the others listed, they just get assistance achieving that price point by reusing many of the original components. Cranks, re-grinding cams, rockers, etc. ATK is owned by LKQ which is a large automotive recycler. You're not wrong saying that 20 ish years ago, when the BluePrint name appeared, we weren't doing some of the same things, But today through vertical integration, reinvestments, tooling, and expansion, we exclusively build 100% new engines. The only core we buy is the Magnum. Every other engine is new from the block up. We auctioned off all the teardown equipment even! Hope you don't think I was slinging mud at a competitor. It's a big enough market for all of us. You've been a longtime customer/ advocate and I can't have you changing your opinion of me!!! HAHA
