I doubt it. The LS1 manifold is the most restrictive of the bunch besides the FWD LS4. The truck manifold likely did about as well as the LS1. Look for an LS6 manifold, or get the Dorman copy.

Actually the truck intake is on par with the LS6 intake to the point that other than looks they are nearly identical HP/Torque wise with the LS6 only edging the truck manifold by a couple HP.
