Not Ranked
The Lunati that I installed in my engine was retarded 6 degrees from the factory, and it said so on the box!! I know that it can deliver more torque by retarding, but why don't they just grind it that way to begin with? I used the Cloyes timing chain and gears and advanced it 2 degrees which still left me 4 degrees retarded. I don't know how it will perform because I haven't cranked it yet, but for sure it did rob me of a few horsepower.
