Finished rebuilding my engine and performed dyno test. In my four runs, power was consistent and peaked at 246 hp and 333 ft-lbs at the rear wheels. I was hoping for more. Below are the specification of the rebuild. This was my first attempt to rebuild an engine. Request input to unleash the rest of the potential in this engine! Should I just change the Carb or bolt on a Blower?
