Hi. We dont have much snow here so I was wondering what the proper motor break-in would be. This is a new rebuild with overbore and new pistons and rings. Should I lift the back off of the ground to vary rpms? Should i use short run times because of lack of snow to cool?? Also what is the clutch bolt torque spec? Its a 94 xlt 580. I would like to break it in and get it ready for the snow. Thanks.
Do not try to break an engine in on the stand. It really should be loaded more than just the weight of the track to break in correctly. You also don't have any cooling without the snow. Just wait for snow and run it for a half hour or so without being abusive and you'll be good to go.
Where I sled: Pounding my way up and down powerlines all around North Bay.

With a Dyno, or not at all. You can't load the motor enough on a stand, and you won't get a good break-in. There's a really good web-page about prpoer break-in procedures, if I have time later today I'll try and find it and post a link.
