JIMS^® Engines

Every design element and every part of JIMS 131" Race Engine has been developed and optimized to produce a balanced, durable and very powerful racing engine. As it stands, unmodified, the JIMS 131" Race Engine delivers 135 ft/lbs torque and 130 Horsepower. It is strong enough to produce much, much more.

JIMS has concentrated development on building a solid foundation for further modifications. There is enough case material to support a bore size of 4.800", substantially thicker than a stock Twin Cam.

JIMS did their homework, built the parts, tested, refined them and tested some more. After thousands of miles and hundreds of dyno hours, the result....a JIMS 131" Race Engine. The JIMS 131" Race Engine was then sent to a renowned independent test lab and tested some more. It passed. It prevailed. it won.

JIMS proudly offers you the JIMS 131" Race Engine, the best foundation for racing possible.

Race use only. The JIMS 131" Race Engine is NOT a street legal engine, its a racing engine. JIMS has made every effort to produce an engine capable of high mileage. However, drag racing is and has always been our primary objective. Every detail including displacement, cylinder heads, cams, carburetor size and ignition maps have been designed, developed and combined for the single purpose of getting through the lights first.
