    Re: Original or swapped N*

    On a Northstar the VIN of the original car is stamped on the side of the engine block down low on the right (rear) side of the block near the lower crankcase split line. You can probably see it thru the right front wheel well if you remove the tire and pull the splash shield back and look at the engine block beside the trans case.
