Made a call to Edelbrock today.

Trouble getting aluminum? I know of about 4 recyclers local to me that have 30 foot mountains of crushed soda cans and hundreds of lbs coming in daily to feed the scavengers 5-10lb a day sales habit. Intakes don't have to be heat treated like a cylinder head so cast 'em with this plentiful 3004 scrap? Edelbrock states they use U.S. sourced material.
