I kind of agree we have a lot of head choices that will make more HP than a stock block 440 can handle right now. So why would you invest $7,000 in heads and related parts or more, in a block that is not a question if it will fail but when? What the Mopar market needs is a cost-effective aftermarket block that is not in short supply and costs twice what a typical aftermarket Chevy block costs. I limited my latest build to 600HP concreted the block and a stud girdle just to try and make sure it would hold up to racing a few years. I have seen a bunch of 700hp engines fail, with distorted cylinder walls and cracks in the main webs. And of course, the catastrophic failures when those distorted cylinder walls crack and hydraulic a cylinder at high RPM.
