You could try going to your local small airport adn running 100 octane low lead (100LL).

Yes, you can mix it. Supposedly, it doesn't stay mixed over time very well - so just shake it or use it up.
Costs anywhere between $3.80 - $5.00 per gallon

If you can get Cam2 for $3.00 a gallon, that would be a good choice. Just check the "Motor Octane" number of that variety of Cam2 that they have. If it's in the ballpark of 97-100, you'll likely be fine for running anything up to 215psi or so (I don't know all of the details of your setup, so there is a little handwaving going on here).

Did you build the motor yourself, or did someone else. You should try to find out the specific octane requirement for your motor. There is no fixed octane rating solely based on compression. The things that are factored into it are also the dome/piston shape, porting, and timing. For example, I know of some builders who can make a 200psi motor that can run on pump gas.

well the motor isnt completed yet.. i was planning on running 33 or 35cc domes which ADAracing says will make about 185-200psi and was mainly just trying to find out kinds were out there and what was the cheapest!! i plan on doing some cyl and case porting along with running an aftermarket pipe.. so right now i have no idea what this motor will put out psi wise. yes im building the motor by myself minus some porting

Like njfl said many factors can determine what octane fuel you should use. Cranking compression is a baseline but you really should talk to a reputable engine builder with your setup to get a recommendation on fuels. I am running a 84mm case ported 62t case with 61x ported cyl and 35cc domes. I makes about 205 cranking but the squish is about .055. I run a 110 octane leaded fuel at $5 gal from a local pump. I have had no problems with it.

I can buy Sunoco 110 leaded at a local pump, so that's what I use for practice.

Prior to racing, I switch to the Sunoco 104 unleaded (called GT Plus) for racing since leaded fuel is illegal (gotta richen up the carbs just a little bit when I make the switch).
