The connecting rods are from C.A.T. Power parts in factory 6.625-inch lengths. This H-beam design rod is lighter than the factory part, and Byron has had them bushed for full-floating pins. They are affordable and warrantied--that's a tough deal to beat. Byron feels no need to run a longer-than-stock connecting rod, as the factory 6.625-inch length is much longer than a comparably-cubed small-block Chevy with factory 5.7-inch or even popular aftermarket 6-inch rods. Note the ARP rod bolts for insurance.
