is it worth the effort? (cam)

going to a longer duration usually gives you a higher rpm band and may give more HP
you loose low end torque
which means to get that or more torque back for launch and after shifts you have to run a looser converter and a lower gear or shorter tire
have you done everything with the existing combination-- ignition curve, carb tune, chassis etc??
360 magnum what year and compression
has it ever been rebuilt?
what's your cranking compression with the carb open?
if yo do still have a good working high (er) compression early 360 motor or the late lower compression one- makes a difference
