really depends on your rear gear and tranny combo..I have 3:73 gears and a th350 with a 2500 stall...I have the comp 268H..Im a little under cammed for what i want, but if I didnt have the gears and converter I would be over cammed...comp cams are fine..they had some bad blanks a while back...now they are over compensating....make sure you break the cam in correctly...use EOS from GM(engine oil suppliment) along with following the directions to a tee...call comp,crane, lunati, crower and anyone else you can find and ask what they suggest...then go with the smaller grind...better to be under cammed then over cammed
