Hello. I'm going to purchase the Edelbrock Performer RPM for my 440 that's in my 71 Road Runner pretty soon.

Before I do, I would like to know if a 3 inch filter will fit or a 2 inch filter and if I need a drop or flat base to have the air cleaner fit under my factory dual call-out hood.

I do not have the car with me to check measurements. What are the measurements that I need to run; taking in for instance: Net height from carb flange, filter height, drop distance and the distance I have to play from the top of the manifold plenum to the top of the hood?

I appreciate all your help.

Thanks,

Adam
