Story summary

NASCAR announced on August 29 that the Daytona Cup will use 465 hp engines and 4-inch spoilers.
The reduction to 465 hp uses a 0.84-inch tapered spacer instead of the 0.89-inch version.
A new drop-gear ratio and underbody aero tweaks keep cars in the power-band longer, aiding passes.
NASCAR says the package curbs fuel-saving and promotes grip-limited racing, though fans dislike the horsepower cut and it may be tested at Talladega when successful.
