This is the Briggs and Stratton Overhead valve racing engine. Fully blueprinted, ready to perform. We use our years of experience and expertise, coupled with our machining capability to transform this engine from ordinary to extraordinary. Standard procedure here at JRPW is to sort and hand select each piece we use, it is the only way we can achieve the results we both desire. To the limits, thats the way we do it every day. Each engine includes all throttle linkages, sleeved header/ muffler assembly and chain guard. Choose your color, and hold on, we are ready.
