280zx front pulley: turf or keep?

[speedyblue]

I'm swapping an L28 straight from a 280zxinto my 240Z. Should I swap the front engine pulley with the 240z one or just keep the 280zx one? The 280zx one seems chunkier. How do they hold at high revs?(7000rpm only, not trying to kill the engine here)

I have a vauge memory of someone saying they don't cope with the revs.

Thanks

Keep the original pulley that the engine came with. There is really not much difference in size just that the original was balanced for that engine.
