USRA Truck Series Engine Rules Changes Announced.
San Antonio, TX (April 21, 2006) - United States Racing Association Race Director Rick Day announced today that two USRA Truck Series Engine Rules are being changed effective immediately.
“We have been watching the competition closely in the Truck Series and feel it’s time for a couple of mid-course corrections,” Day said in announcing the changes. “It’s never good to change rules during the season, but we felt these changes would really help even the playing field.
The two changes pertain to the Chevy 305, Ford 302, and Dodge 318 engines:
1. The maximum compression ration is being raised from 9.5:1 to a maximum of 10.5:1
2. The maximum hydraulic cam lobe lift is being raised from .313 to .333.
The rest of the engine rules will remain as written in the 2006 USRA Truck rules.
Any questions about these changes should be directed to Rick Day at (210) 827-4524. Rick’s email address is rick@sanantoniospeedway.com.
