I know someone who want's to swap the truck intake for the F-body/C5 intake for more upper RPM power,what all would need to be done for it to work? Thank's,

I thought all hte vacuum lines and electrical connections were a direct fit, but I'm not sure.

How much torque do you lose with an LS1 or LS6 intake?

 

This has been posted before. The truck intakes are better for our trucks than the LS1's. You may get some increase with the LS6 manifold however.

If you are going to change the manifold and are willing to pay a high price. The new FAST intake is out and that may produce a couple more HP than the LS6.
