When I read this;

“We can’t keep pushing a 3.580” crank and 6.200 to beyond 1,000 hp,” Weber says. “We need to add some displacement. So we add a 4” crank with a 2.100 GM rod journal. That’s about as much as we can stretch and still be able to get the packaging correct. I like the 4” with the 2.100 because it has overlap between the rod journal and the main. That overlap is what transmits all the power from the engine. When you fail or flex a crank it’s because there isn’t enough overlap. The last journal transmits every bit of power and shock from every cylinder. The overlap between a rod journal size and a main size becomes really important.”
