If you need to retarded or advanced a cam to use it , you have the wrong cam.
Iowan, this just isn't correct. This is a custom cam that was ground 108 LSA on a 102 ICL, advancing a cam that much, combined with a narrow LSA has proven to provide a ton of torque. However cam advance is one tool that we use to make the engine do what we want by shifting the tuned peak as well as controlling cylinder fill A 108 LSA cam is commonly installed on 108 (called straight up) or even if using a generic 108 LSA box cam would be ground at 104. That's three viable options with the same cam. To think you wouldn't build an engine and manipulate intake centerline to your advantage is at best trusting the cam guy, at worst giving up power.
Now, lsugymrat bought this cam for a 390, yes that is true, and when doing that, picked a cam that is on the small side for the 445, however, that cam when installed straight up, will do absolutely fine in his heavy car with a stock tranny, converter and gears. It will also have the potential of making over 450 HP, which of course is not the peak a 445 could make, but with well into 550 lbs of torque, and pump gas friendly, should be very fun in the car.
Happy to discuss cams in detail, because all the valve events matter and interact with each other, but some of the comments concern me because you can't just look at .050, LSA, advertised duration, lift or overlap alone, each one plays upon the other
