What Carb for Poly Stroker

You're kinda unclear on the cubic inch displacement.....at least to ME. You say 354 stroker. Does that mean it is a 354 NOW or that you began with a 354 ? Is 354 the current displacement? Chrysler did make a 354 Poly engine, so that's why I ask.
318 poly. 3.58" crank. 0.065 over. 354 current cubic inches, as opposed to 4" crank and 390+ cubic inches.
