Every design element and every part of JIMS 135" Race Engine has been developed and optimized to produce a balanced, durable and very powerful racing engine. As it stands, unmodified, the JIMS 135" 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.
You want strong transmission? JIMSÂ® has strong! JIMS Fat 5 Overdrive is simply the strongest, toughest gearbox made. JIMS took advantage of its new, more compact shifter technology to increase the width and strength of every gear. The width increase varies from 18% to 53%, depending on the loads each gear set must carry. Big power is more popular than ever. Large engines like the JIMS 120 deliver double the stock power and torque. When such power is linked to the ground through high torque clutches and big sticky tires, the peak loads on transmission gears rise far above what stock transmission gears were designed to endure.
