cd,I agree with you,the roller would make more power.better duration for a 327 and more lift.The power would increase everywhere,including the bottom end. A bigger cam does not "always" mean a loss of low rpm torque. neutron meters and kilowatts are different ways of expressing something that humans can kind of understand.
and thanks for reiterating that a wider power band is required to match transmission ratios.
I no longer have a desire to argue here. 327s make power at higher rpms than 350s.putting a smaller cam in a smaller engine is not entirely accurate for rpms. duration is time,lift is flow,o
