I know it's been awhile but I'm looking at putting the same cam in my 2004 5.3 RCSB. My question is how do you think the LS6 intake would respond to this cam on the 5.3 (also what would it do to gas mileage)? Though about putting a new torque converter for the loss of torque.? Also have hooker headers super comp (1-3/4") to install. Any advice greatly appreciated.
