opinions on stroker kit?

I got word back from my machine shop that my 340 was seized up from a spun rod bearing and bent rod on cylinder 5. I will be talking it over with them Monday. But Im now shopping for a stroker kit.

The best pricing I have found is from RPM Machine http://www.rpmmachine.com/chrysler-stroker-menu.shtml
Im intrested in the 416 cast crank for the price ( comes with KB hyper dished pistons) but I believe I can maybe get it with forged ones. Or should I step down to the 372 and get forged crack for a little more money?

cast crank more cubes or forged crank less cubes all for close the same money?
