Comparing these two cams @ .050 duration is really a crap shoot & does'nt tell you anything , seat to seat timing #s will give a better idea on how these camshafts will behave (.004-.050") , could be chalk & cheese.

Depending on intensity #s the smaller stick may be longer @ overlap & be a dog down low.







You really would want more info on the cams lobe profile. With roller cams the 0.050" number only gives a general idea of the cams RPM range, but not the info needed to compare to fairly simular cams. What is the $130 "custom" cam? For that price I would guess it is a reground stock cam?
