Builders: Square engine, Over Square, or Under Square for you?

Take a 400 block and add a 3.75 stroke. It don't get much better than that.
You can rev a 451 to the moon if you have the top end to handle it.
If I was to build a stroker it probably be 470 is the biggest you can go and keep all the so called ideal bore stroke and rod ratios. I get that the short deck 451 is ideal for the 3.75" stroke but I'd have a problem stroking an engine ($$$$) that ends up same size as a overbored 440 :)
