Best Carter 4 Barrel Carburetor for a stock 273?

That can be resurrected? Based on the pictures it looks like it's corroded and/or seized-up, and more of a core than anything else.

Of course I could be wrong....
You are, The "corrosion" is fire retardant from an extinguisher
Not seized up
It is a core, im not presenting it as a slap on carb.
