In today’s announcement from NASCAR R&D amending the Nationwide Series Rule Book: section 20A – 5.10.4 is amended as follows:
“At all Events, unless otherwise specified, all engines with a cylinder bore spacing less than 4.470 inches must compete using a tapered spacer with four (4) 1.125-inch diameter holes. At all Events, unless otherwise specified, all engines with a cylinder bore spacing of 4.470 inches or more must compete using a tapered spacer with four (4) 1.100-inch diameter holes. Unless otherwise authorized, the carburetor restrictor will be issued by NASCAR.”
