Rule Amendment Brings NASCAR Nationwide Series Engines In Line
DAYTONA BEACH, Fla. (July 23, 2008) -- NASCAR issued a technical bulletin Tuesday amending the NASCAR Nationwide Series Rule Book. Effective as of July 23, 2008, 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."
"Eventually, all teams that upgrade to new engine packages will be subject to this rule modification," said Robin Pemberton, NASCAR vice president of competition. "Over the years in our sport, we've taken steps on numerous occasions to help maintain a level playing field among our competitors and we will continue to do so."
