1974 Nova Custom LM7 Swap - Speed Density Question

[Brians74Nova]

I bought it with a Swap already done (kind of). The person I bought it from didn't know much as he bought it from someone who lost her husband and she didn't know either. So as I go along and learn both classic car basics I am also learning about LS swaps (I know it's an LM7). I can assume this person did quite a bit to the engine since it has a nice Holley Pan, Cam kit, etc... but I just don't know everything he did. First thing I need to figure out is the IAT sensor (Missing) and the MAF sensor (Missing). I am starting to wonder if it might have been deleted and converted to speed density. How would I check for that?

UPDATE I finally found where they hid the damn plug for the MAF/IAT They had it hidden inside the fender.
