400/426 Stroker. Ever heard of one?

Even though I don't agree 100% with moggoblue9798, I just think the focus on stroke alone is wrong, extra cid = equal extra fuel and air(tq), more piston surface = more psi across the piston to be multiplied, + the multiplication effect of stroke = tq, it's all interrelated. Most overlook piston surface. There's no free lunch :) eg.. 360 vs 361 or 400 vs 408 or with OP 426 vs 426.

But to say he's plain wrong is wrong.
