Best carburetor and intake manifold for a 273?

I have the Edelbrock sp2p. All it really offers beyond 4 brl is dual plane, Improved low end torque.
You could get that from a later model cast iron 4 brl intake. Any would have the larger runners and create steps at the 273 heads though. The sp2p does match the 273 heads.
Performer intake today, different heads tomorrow ? It will always be just a 273 at heart though.
This doesn't mean I don't love my 273 in my a-body. I'm adamant about having more stopping power than going power so....
