Yes, 36 mm are the right size.

But you better have a really long wrench

36mm is the correct socket size but the torque on this sucker is huge, something around 300 lb ft. If you are building a really hi-po motor you should consider the Frank Fahey crank hub, expensive but worth it. I have seen front hubs crack and break on track/race cars that are driven at high rpm consistently. That being said, I have also seen stock motors go on track and run for thousands of laps without a problem. It probably has something to do with driver smoothness and just dumb luck.
