I just finished my 350 build and was curiouse as to the best method for breaking it in. I am not going to be driveing it still for a while it has no interior and no lights. I was just looking at moveing it around the yard and in and out of the shop tell I get it painted and back togather. I am I safe driveing it that little bit or should I wait to be running it tell I can get it on the road?

Thanks
