What is your build? Hard to beat the RPM but your stock air cleaner will not fit under the hood w/o a drop base. Many options around, Street Dom, M1 dual plane, even an old CH4B will be better that the stock unit. You should be able to use your stock linkage on all of them. I've used CH4B, Torker, Torker II, and RPM w/ all the stock stuff.
If you grind the "Edelbrock" off the CH4B and paint it, most will think it's stock.
