I didn't read the whole thread just the few last posts but did you tune it? I doubt a ZR1 cam would work on a 4.8L properly without a tune. Sports cars generally focus on top end HP rather than low end torque unlike trucks. The stock 4.8 cam you had was probably better down low not to mention it was tuned for it.
