So Im installing the 6 pack intake on the 70 Bee. Do to engine work-I did not know about- I did not want the iron intake shaved so Im letting them do the Edelbrock intake. 1970 I believe all if not most 6 pack intakes were iron so they would be the engine color. Trying to go with correct period look. I have seen a 70 GTX with the aluminum intake. What would you do? Thanks Dave
