Of course comp cams is in the business to sell cams, not give advice on how to make an existing cam work, so i guess i shouldnt be surprised that they didnt suggest advancing the existing cam.
btw, i know that a cam can be installed advanced or retarded by moving the timing gears, but how do you "alter" the centerline? This is how the cam is ground...
on a related note i dont think any cam would make a used vortec 350 with tbi in a 4x4 3/4 to. Truck with 265 70r16 all terrain tires "boil the tires"...
