Has anyone moved the MAF on the LT1 anywhere else?

This is sort of interesting reading.

Think we can use the MAF inlet from this car on the LT1 FWB?

It can support 500 hp, so it should be able to support an LT1, eh?

Unfortunately, many people rely more on shade-tree mechanics than true technical theory of operation when making performance mods to their cars. Because of this, it is quite possible to make a mod to your car that would "seemingly" unleash trapped horsepower/torque but actually does little or even results in a loss of power under certain operating conditions, if not all.
This intake tract mod is a perfect example. As was fairly well pointed out in the thread above, there's a lot more involved than one might think and certain changes made "could" have adverse effects on the driveability AND peak performance of your car. This is why I would stick to what has been tested and documented rather than what "some guy said" on a website somewhere. SOTP testing doesn't count either.

I have been wanting to do some moving of the MAF to get it closer to the TB and to straighten out airflow.

Mainly I think most theories on the air box are flawed. Most people think about the air as it is being PUSHED through the pipe. It is in reality "sucked". But I know you phyics guys will argue with me on it. How does it affect airflow? I suspect that the FAIK kits rarely gain much power. I have removed my first base, I think it has improved some, but at the obvious expense of noise. I am pondering putting it back in. No fuel economy improvements.

When I get to the track this year I will test both, with and without. My problem is that I am not an experienced drag racer, so I am concerned about my consistency.

Maybe use traction control to be consistent?

My K&N kit DID give me a little boost. From what I've seen on dyno charts, the K&N kit is good for maybe 10-15hp at most. You're right about the physics guys giving you a hard time. I'm resisting the urge to correct you too. ;)
