Higher-octane fuel will do you no good and gain you no horsepower without the compression boost to require it. In fact, high-octane fuels can actually cost horsepower on a stock or mild engine, as the higher octane ratings make them harder to ignite. Good pump gas of 87-91 octane is MORE than enough for a gas 3020. If your '65 still has the oil-bath air cleaner, which I believe it would, airflow potential can be gained by installing an appropriately-sized dry air filter set-up in place of the oil-bath. I later 3020 paper element filter housing may bolt in, I can't say for sure. If you want to keep the oil-bath and optimize its performance, check the adapter on top of the air cleaner housing. It is located between the intake pipe and housing. There's a screen in there that can get plugged up after years of dirt and dust and can decrease airflow quite a bit. As far as spark, the easiest upgrade is an electronic ignition pickup in place of the stock points. Make sure to get the proper polarity for your tractor, either positive-ground or negative-ground. I won't say that an electronic seet-up will increase horsepower, but starting, throttle response and fuel economy will be improved. And you can run a wider plug gap for a hotter spark. Beyond that, getting the stock distributor rebuilt, blueprinted and recurved can increase performance quite a bit. As will solid-core wires. As far as the blower, are you referring to a turbo set-up as was offered for the diesels? One could probably be installed, but it will take some work to make it all function correctly. The main change that will need to be made will be to the carburetor, as pressurizing it with forced-induction will throw all of the factory calibrations off, and it will need to be modified in order to be operated "under pressure". You might also need to upgrade the fuel pump, as the stock units don't provide much pressure. What exactly are you looking to do with this 3020?
