got a 70 1/2 lt1 z28 with rs package. now how do I Identify if this stuff is all factory. the cowl tag says z28 on it but thats as far as I have gotten. it is also a auto turbo 400 car. from what I have been told this is a pretty rare car with the auto like 300 something made. 365 horse 350 lt1 motor, split bumper and the right front end. it needs paint but its not rotted as far as I can tell. and may need motor freshened it smokes a little but it has been sitting also for 6 or 7 years
