Came out of my 2011 800 4. Packard Performance ported head with Ferrea +1 valves, Kibble White springs, Wisco 10.5 Forged Pistons, new Polaris cylinder, welded and pinned crank. All work done by Jedd & Jace @ Packard Perf. Runs great without a turbo and with one. Was built to run 12+ lbs of boost and only selling to go Z1. Very clean engine that will come with everything from injectors to exhaust. Still in Rzr and can hear run if needed also pics can be sent. Asking $2600 + shipping. Thanks for looking.
