408 vs. 440: Which Would You Choose?

Just out of a curiosity, how does a souped up 440ci small block with great air flow and equal compression compare? The small block has more stroke-doesn't that help with street-ability in regards to equal output?

What's his face ({BPE/BME??} am blanking out, asparatame? CRS?) sells the 4.125 or 4.25 cranks for the same price as the forged 4 inch cranks.

What about 440ci SBM? Is it really so unattainable?

I don't think we can get the over-bore from a magnum blocks, people have over-bored 340's & 360's a hundred thousandth's...

RAM says he doesn't like the 4.25 ?rod ratio's?? Wear on the bore??

Is this the anchilles' heel answer to my question?
