Stroker physics - where the differences are?

Not that it's a small block,but thats whats beautiful about the 451 stroker. Stock 400 bore is already biggest of the big block mopars,the 3.75 440 stroke is all stock parameters, and if you use the 440 rod you end up with a very light piston. You then have a quick revving big block without the usual stroker issues associated with a long arm. The crank also gets lightened some during the build as well. It's really a win win combo.
