I'd say semi easy drives(but don't be a puss) for 150-200 miles to break in the rear gears,tranny,converter.

The point is to seat the rings good,this happens in the first 20 minutes it runs which gm does.

My procedure is hard.Starting my 427ci next week and will hit the dyno on startup to seat the motor.After a heat cycle it will get WOT pulls.

For people hammering a car off the lot that is not good at all.It will cause premature wear of the clutch,A6 tranny and rear gears.Might not notice right away but they will fail early in life. Stuff needs to heat cycle and seat in.

Thats what I have been saying...
