gmpp intakes ok i have been searching for intakes for my 408. decided i want to go carb style intake with 4 barrel throttle body. the rpm range on the gmpp intakes are closer to my cam ,than the eddys so i want to go with the gm intake. ok now the question is, there are 2 part numbers ,one is 2553416 and the other is 25534401.now i have asked several places if the first number is the one with the holes machined for injecters, because it is listed as efi but none of them can say for sure or they just say no. so witch one do i need.has anyone actually bought one? they are identical except for the holes right? the even have the same part number cast on them. please help.
