im looking into fitting a light weight crank pulley too my k series engine i want to keep the same dimensions tho will there be any neggative effects or will it just let my engine rev quicker

Don't think that a lightened crank pulley will make much odds as it's not particularly heavy to start with and not a very big diameter.

Is the standard pulley also a harmonic dampner?

don't think so im just trying to save as much weight as possible if its any help its a rover k series

It would seem that the pulley isn't a TV/HD.
