Sucks you have to go through this but my guess on the full story is the intake you were shipped was a return to Summit as it came shipped in a brown box and not an Edelbrock box. Edelbrock addressed this issue months ago and all of the intakes they are shipping are good which is why I am thinking what Summit sent was a returned (unused) item.
I would return the intake and reorder from Edelbrock or somewhere else. Chances are slim to none that you are going to get another returned part.... especially if you order from Edelbrock.
