LS6 Intake Swap

[ducky]

What is it about our truck intakes, or I guess whats the difference in the LS6/LS1 intake setups that it allows to climb higher than our truck intakes?

In general, short runners are for higher rpm, which are normally installed on cars because they are lighter, and rev quicker. Long runners produce more torque on the lowend.
There are obvious differences also, but that's one reason to install an LS6 intake.

What kind of numbers are we talking about as far as losing lowend torque when installed the LS6 intake? Are they that noticeable?
