Sure Sellers:

• With proper induction, exhaust and head modifications, this Big Bore kit will easily match the power output of a Jims 131-inch race engine

• Kit includes a set of 4-5/16-inch cylinders, a set of 4-5/16-inch pistons, and all necessary head and base gaskets

• Since the 131-inch engine was based on the same stroke as the 120-inch, other parts, including the flywheel assembly and cams can still be used
