no, forged rods are the same exact specifications as stock ones, in terms of shape and function. I have forged rods with stock camshafts and stock crankshaft.

Changing the rods simply does not change the power output of the motor.

i understand, but my idea of replacing the con-rod is with "lighter" con-rod material, if it is lighter, i think it will affect the lower power band. that's why when i change to the lighter rod, i will also change the camshafts. what do you think?

it seems that we have a misunderstanding about the dyno method. as i mentioned before, it was on engine. for the next step i will use on the wheel

Reducing conrod weight will have only a very marginal effect on the reciprocating mass. In other words, I severely doubt if you could tell the difference while driving it.
