So Tony showed me what they do...
Here is the Stock LT1 TB, notice the huge lip and the very large crossbar... Both which would greatly affect airflow... (I get this as a Professional Pilot and Aeronautical Engineer)....
Here are the areas they "port"...
And the end result...
As a guy who works with good airflow keeping him alive, that looks like a pretty good improvement to me...
I'll report back in a few weeks when I receive my intake... But at this point, I'm pretty optimistic...
