JIMS ® 131" BIG BORE KIT...

An easy solution to convert your JIMS 120" into a 131”. These kits are designed to work with an existing JIMS 120" Race Engine. The kit includes a set of 4 5/16" JIMS cylinders and a set of 4 5/16" JIMS pistons. These are the same cylinders and pistons used in the JIMS 131" race engine. Since the 131" engine was based on the same stroke as the 120", other parts, including the flywheel assembly, cams, etc... can still be used. With simple case boring - and this kit - your 120" can be converted into the awe- some 131" engine. Kit includes head and base gaskets and a center case bolt. With proper induction, exhaust and head modifications, this Big Bore kit will easily match the power output of the JIMS 131" race engine. This kit offers a great cost alternative for the customer that has already purchased a JIMS 120” engine. See instruction sheet No.1308-1350 on JIMS website.
