I am interested in hearing if anyone has any views on oil consumption during the first 1000 miles a GM ZZ383's life. This was a long block assembled with all specified GM part numbers. Thus far my motor is using oil at a rate of approximately 1 quart every 325 miles. I am at about 600 miles now and wondering if this is just part of the break in. I was lead to believe that the plasma molly rings that come with this motor are supposed to seat very quickly. But I have read that in the past the big block crate motors had problems with these rings and oil consumption. I can not seem to find any informatin on this topic and would appreciate any feedback.
