Check out Part 1 and Part 2 of this series on building the next generation race engine!

Welcome back to Circle Track’s continuing experiment to see how an engine based on LS7 architecture will work as a full-bore dirt racing engine. Yes, Chevrolet Performance does sell the LS-based CT525 crate engine, and it is a great option for crate racing. But we know this engine design is capable of so much more, especially thanks to ever growing aftermarket support. And besides, why settle for a “mere” 525 horsepower when you can shoot for 600 or more?

In previous installments of this engine build we took a closer look at the major components and why we chose them, and we also documented engine builder Bob Cronin’s pre-fitting process. This time around we are finally putting parts together, and we’re happy to sit back with a Coke while CRD Engine Development’s own Cronin and Rick Fred does all the work. While Fred was assembling our short block, we could hear some of CRD’s LS-based sports car racing engines wailing on the facility’s two dyno cells, and we can’t wait to hear this 400-plus-inch bad boy fired up for the first time.
