'79 280 engine swap ???

I have a '79 280zx 2+2.. I blew my head gasket and am about to dig into it. But I started wondering what else could I do to make this car what I want it to be.
What other engines can be swaped into a '79 280 ??
Is an engine swap even worth it?

Any info that anybody has would be helpful... thanks.

Well... what do you want it to be? What kinda performance? can you afford it?

I'd say keep it simple and swap in a L28ET or another L28E and just supercharge it...
