This "size of your crank" thing has gotten way out of context. Besides, I thought it was about con-rods, not Johnsons.
Low RPM, high TORQUE engines tend to have very large heavy con-rods & pistons, too. AS the need for speed (rpm) increased, the mass of the moving element in the engine (again, con-ron & piston) rapidly decreased. On second thought, the johnson does apply. Higher reving engines tend to have shorter cranks.....
I also don't dispute the HP capabilities of the PowerStroke engine, if you can afford it! Those injector prices are sky high.
