Todd, you (and others) should make use of the search tool that John 
Gwynne put on the DIY home page..... ;-)  Find it at:

Here is what it found using a context search for LT1 MAF:

I've seen several questions/comments about the output of GM MAF sensors. 
I ran an airflow vs. frequency output today on the LT1 MAF that is used 
on the high output aluminum head version (F and Y car) and also on the 
LT4 (Y car). This is the largest diameter MAF sensor (3.5" O.D.) used on 
GM engines I beleive, so it would support the most HP. The flow is in 
grams/second and the output is in kilohertz.

         5gm/sec =  2 khz (idle)
        50gm/sec = 5.0khz
       100gm/sec = 6.7khz
       150gm/sec = 7.7khz
       200gm/sec = 8.5khz
       250gm/sec = 9.2khz
       300gm/sec = 9.7khz
       335gm/sec = 10 khz (max)

I hope that's of some value.

Great tool if used!   Thanks, John!
