Thoughts on Gasoline?

What I do know is that in April of 1940 Nebraska University tested the 9N tractor and rated it at 20.29 draw bar horse power. I have documentation that shows the testing being performed with Mobile 68 octane gasoline. My question is with all the improvements in gasoline since 1940 how does that reflect in draw bar horse power with our old 9N's today?

Octane rating is basically to control spark knock or pre-ignition so has no bearing on energy produced. I mention it because it is available knowledge.

I think we need to take a good running 9N and put it on a modern "Dyno" and see what the results are. My guess is that with the improvements in the refining process we may see a performance increase of about 20%.

I still think the old flat head V-8 would have produced more horse power if it had better pump gas. What do you guys think?
