How much more power can you really make? Do the BB 530's flow much more air then the 500's? How's the torque curve? Are the BB's designed in a way to allow productive higher boost levels? I've got an old set of 500's now and am considering an upgrade along the new exhaust manifolds etc. If its deemed productive I'll do the cams as well. Any opinions appreciated...thank you.
