Comparing the newer comp cams version to the MP one is not an apples to apples comparison.
You can use this cam with less than 4.10 gears and 3500 stall and get good results.A lighter car will not suffer as much as a heavy car in this situation.
Case in point 25 years ago I had a 440 6pak in my 70 charger r/t with the .509 cam,4 speed,and 4.10 gears.It ran like a raped ape.I put the same motor in my 72 charger behind an auto with a 2000 stall and 3.23 gears and it was a PIG until you got above 3000rpm.I was 19 years old and that was my first lesson in gearing(lack of) and camshaft operating rpm.
