holley identification??

I came across a carb, and I think it might be an 'economaster' but I am not sure. The seller gives the following information "there is a #487 on the butter-fly, Other #s are 6R-5643B 1-8149-1 0220"
I think a 450 economaster would work nicely with my L6, and not bog down the engine like it does on some of the larger displacement engines it was previously run on, but I am not sure what this carb is. I have attached a pic below.
