Ready to go HUGE with your JIMS TC88A or TC88B engine! These kits are all new with our new pistons provided by Wiseco. We’re partnering with T-Man because of their experience with these engines, their superior customer service, and their development of other parts that compliment this kit, creating a total package that delivers 150 ft./lbs. torque and more than 150 rear wheel horsepower! The bore is blown out to a whopping 4.375 with a pump gas friendly compression ratio. As with all Revolution Cylinders, they are warrantied for life against warpage and plating defects! The kits come complete with Revolution Cylinders, forged piston kit, and gaskets.
