What does this well-worn '57 Chevy have to do with modern stock car racing? Not much, except that this is the beginning of Chevrolet's 283 V-8, which appeared in all types of Chevys for many years. These engines use a connecting rod with 2.00-inch journals. If your rule book requires stock rods, you can reduce some bearing speed (and friction) by turning down the rod journals from 2.10 to 2.00 inches and using rods for a 283.
