what flywheel for a 273 128 tooth. with a 360 bellhousing

The 273 is going into my little racer.
While I build my racing eng.
So it should be good with the right pilot bushing. Any flywheel cluch recommendation?

That's another ??. Do I rebuild the 360 or what I think I will do is go big block.
383 Has a shorter stroke and I think easier to get parts.
I wish I can that 440 HP CHP Interceptor I had in the 70's
