Alright So I have a 67 Mustang With a Ford 427 Sittin in my garage and I have been working on it lately... It is setup for drag racing and due to when it was put together by my dad the engine still requires leaded fuel (which racing Fuel is leaded) we have been tuning it up and stuff using regular 93 octane but I know what were doing to the inside of that engine and its killing me I am near the peoria area of Illinois does any one know where I can get 97+ octane leaded fuel for this ???

You can try locating a place that sells VP race fuel... such as link below in sources section:
Also another place you may want to try is local small airports.

any engine that had the heads worked since 1977 by a major engine rebuilder( or at least machinist) has installed hardned vavle seats for unleaded gasoline. check the compresion ratio using the various tests (smokey yuchknic is best) and see if you even need 97 octane>

Do they still sell the octane boost in auto parts stores? At any rate, you may want to change the valve seats and the valves. You should be alright then. good luck.

You dont need the lead additive if you have hardened exhaust valve seats.
What`s the compression ratio? if it`s really really high , then you need racing fuel, because High octane actually resists exploding.

leaded fuel is no longer available, Thanks to the E.P.A. you can run unleaded high octane in your motor, but you must have the heads removed and have the valve seats replaced with "hardened" valve seats to prevent possible valve damage from burning unleaded at high RPM,s in older motors
