CRATE ENGINE CHARACTERISTICS
ROUSH Crate Engines are high-performance engines that are based on and operate like the engines designed and produced in the 1960s and later. However, unlike engines of that time, ROUSH Crate Engines (like other crate engines currently manufactured in the marketplace) produce significantly more power and torque. As a consequence of this, these engines have characteristics different from the original production engines upon which they have been based. The following characteristics are not covered by the ROUSH Crate Engine Limited Warranty and should be considered before purchase.
Additionally, It will be the sole responsibility of the installer/end user to select components and optimize the vehicle system based on each vehicle's unique characteristics, and it's intended use. This includes, but is not limited to the selection and/or optimization of the vehicle cooling system, air flow adequacy, A/C system performance, etc., and the suitability of the vehicle and its systems for the end use and environment (weather conditions, altitude, etc.).
Specifically ROUSH Crate Engines:
- Are assembled with larger operating clearances
- Will likely have a rougher idle due to the high performance camshaft design
- Will likely make more mechanical noise
- Will likely consume more oil during normal operation
- Will generate more heat due to the increased power level
- May exhibit non-production-like drive characteristics at various speeds and load conditions
- Will likely consume more fuel due to the increased power level
- Will produce +/- 2% of the advertised power
- May, as configured by an installer or end user, only be legally used in emissions-exempt applications.
