The cam you have now, should be the same grind as the Ranger roller. It is ground with very conservative lobe center lines and has only .355" of lift at the valve: not the best thing for gas flow. Unfortunately, even if it is re-ground you will be stuck with a fairly wide separation angle and an Intake closing event that won't do a lot for cylinder filling. I have been building 2.3 motors since the 1980's and I have tried a lot of cams. You can't go wrong in opinion, if you pick up a Racer Walsh Stage 1 cam. It is a clone of the Ford MotorSport A-237 grind, which is probably the most versatile grind you will come across. You can use your current roller followers and if your valve springs are in reasonable shape, they will work with this cam. I would suggest an adjustable cam sprocket as well.
