Default VP to Sunoco reference

Is there a VP to Sunoco equivalency reference chart anywhere and typical tune changes between fuels?

For up to date and correct specs, go to each manufacturers web site, the specs change often.

Is there a leaded fuel with a lower octane (100 or less) out there that is NHRA Approved?

What you want to pay attention to is the SG and RVP of the different fuels. Similar specs on both will usually need similar jetting and perform close. If either deviate you will likely need to make changes. As far as lower octane than 100, what are you looking to lower octane for?

I have a 9:25.1 Compression Ratio Motor. It would run much more efficiently on a lower octane fuel than 110.
