are the casting numbers different on the different engines??? i have a guy who says he has a 3.8 motor built for a supercharger with only 20k miles. i want to make sure that this guy isn't an idiot trying to sell a normal 3.8. my friend says i can take oil pan off and look at the seam on it. he said the forged crank will have a thicker seam, almost a 1/4 across. are there any other ways i can tell if this is infact built with forged parts without taking it apart???
