470 vs. 500?

Personally I'd go 470 cause pretty much the biggest you can go and maintain good bore to stroke and rod ratios and plus it's capable of 500-600 hp easily. Above that I'd go stroker . To me you either add the torque through the crank or gears.

It would be nice to see the mileage people are getting with there strokers since they've been around long enough to prove or disprove longevity on stroker engines.
