5-101.bk Page 2 Friday, March 17, 2006 11:05 AM SPECIFICATIONS higher horsepower ratings and future emission standards. These changes require increased displacement, higher peak cylinder pressures and a superior engine cooling system. This was all accomplished without a substantial change in engine weight. Improved Design Compared to earlier designs, the E7 engines include improvements required to accommodate Engine General Specifications *Wet includes oil and coolant Engine Features Page 2-2 200 SPECIFICATIONS Characteristic Description Weight (wet*) 2300 lbs.
