I think the compression in the bigger motors is too high to do a pull start but if you can do it post an update.
Reminds me of a bad joke.
Guy was stranded on the highway, dead battery. Blond pulls up and asks if she can help. he says "yes, I need a push start but need to get up to aobut 30 MPH before the engine will turnover on its own". She says ok, jumps back in her car, backs up about 50 yards, floors the pedal and gets her car up to 30 MPH. The rest is history...
