Not the exact same but, I fit one under the hood of my 69 Road Runner with the stock un-silenced air cleaner housing but, I did have to put a shorter filter in it to make it work. Even with the shorter filter, it was close. I never slammed the hood due to fear of outtie dents; I would close it and push down to ensure it was latched. Never had an issue though.

Although you mentioned not using one, I later put a drop base in and used the stock filter size.

Even later than that, I switched to a DP4B intake and use all the stock stuff now. The DP4B is about 3/4" higher than the factory intake which, will go back on the car at some point.

I'm interested in the FAST class so; I've slowly been shooting myself in the foot performance wise. I've just been curious to see the effects of the changes and have been doing them in steps backwards.
