mopar aluminum intakes

Part numbers and casting numbers aren't necessarily the same thing. The numbers on the stock intakes are casting numbers. The numbers that are on the LD340 intakes are a part number (although they are cast in), this intake was available over the counter at a Mopar dealer or any Direct Connection dealer. In some cases the casting numbers were the same as the part numbers but not always this is why it is easy to get the two mixed up.

What perfacar is saying is that the Mopar part number LD340 did not come on a car from the factory therefore NHRA does not allow it for use in Stock Eliminator. Now some other sanctioning body may allow it's use but NHRA does not and from reading perfacar's past posts I know he means NHRA.
