That should work, i just went to the local Auto Zone and got mine. They had several to choose from, It depends on what flavor you like, I picked Holley! Oh well. I had one with the lid that was also a filter element and she backfired once and burned right through it so i would say stick with metal top. Also all are not created equal so i also got a 1"1/2spacer to raise the filter base.
The Edelbrock foam filter top will catch fire. The K&N Extreme filter top is nice when you have limited space and need the air flow. A nice arrangement is a stock Ford dual snorkle(Mustang) air clear with it ducted to the core support to draw in cool air. There is an aftermarket air cleaner with same arrangement(maybe Spectre). Open air cleaners are cheap, but draw in a lot of hot air from the engine. Any good 14x3" air cleaner should give you sufficent flow. Lot of choices.
