The problem with your data on first couple pages of this post is that you are referencing mostly manufactures rated specs. Not true dyno results. A engine marketed as making for example 70 horsepower and 426 ft/lbs of torque when it mass produced every engine varies in performance. It might actually make 71 horse and 430 ft/lbs of torque for example. My point is that the rated specs are rounded off approximate numbers. To prove my point I have put gathered resources from Nebraska dyno tests to shine some light on this. All engines are same stroke and bore, same engines basically just different fuel application. All numbers are peak torque and horsepower results from test records.
