I'm a firm believer in using what is on hand; selling the 2 and buying one is a possibility, only one of them is a sure sale at the moment, may be a while before anyone wants the Edelbrock, in the mean time, times a waistin', you're wanting to drive your car only you can't cuz no one has bought the other intake and you don't have any spare cash to buy the new one yet..........
Just bolt one of them down, and have fun with the car, not gonna make a real big difference which one; you're not building a Pro Stock engine, so don't over think what you're doing.
Good luck and have fun.
