The crank has had the rod journals turned to 2.2-inch diameters to accept Chevy connecting rods. This opens up rod choices tremendously, and Kent has chosen Eagle H-beam rods in 7.1-inch lengths. The big ends of the rods have to be machined slightly thinner in width to fit on the Buick crank, but it's not difficult and does not affect the integrity of the rod whatsoever. The rods weigh 852 grams and carry a part designation for Chrysler 426/440 engines using Chevy rod dimensions (PN CRS7100C3D).
