Are there any concerns, negatives? postitives?
the (only) negative afaik is that it will flatten your wallet. The positive is it's the best plan for a high DCR/fast curve eng to elim deadly pinging. You'd want to add your quantity in the middle of the tank or else slosh it around thoroughly for a uniform mix. If you build a monster it needs to b fed properly. EDIT Forgot about the lead content advantage for your valves/seats but it'd take alot more than a gallon to have a positive effect on that

One gallon in a full tank wont do anything but waste $$$$$.I run 112 in my 440 on the street at times.It has 12.5 domes so it helps.Usually I just run 93 and keep my foot out of it.Rocky

Thanks Guys, exactly the feedback I was looking for. I was curious if it was worthwhile. I have heard that a 20% mix is good but not sure on that. I guess I will just keep on pump gas since i have no pinging issues.
What is your compression now and where is the timing set? 412 is a SB?

I used to run it 50/50 in my Harley..Clean burning and really livened up the bike..  A gallon will make zero diff in your car...try 4 gallons in a 16 gallon mix..
1972 Road Runner / GTX 440 4spd Dana 3.54 Just about to turn 26K original miles..

If you love someone set them free..
If they come back it means nobody else wanted them either..!!

av gas is not pure gasoline that is a myth that is old as I can think of. IT has a much higher lead content.
The main petroleum component used in blending avgas is alkylate, which is essentially a mixture of various isooctanes, and some refineries also use some reformate. Avgas has a density of 6.02 lb/U.S. gal at 15 °C, or 0.721 kg/l, and this density is commonly used for weight and balance computation. Density increases to 6.40 lb/US gallon at -40 °C, and decreases by about 0.5% per 5 °C (9 °F) increase in temperature.[1] Avgas has an emission coefficient (or factor) of 18.355 pounds CO2 per U.S. gallon (2.1994 kg/l)[2][3] or about 3.05 units of weight CO2 produced per unit weight of fuel used. Avgas has a lower and more uniform vapor pressure than automotive gasoline, which keeps it in the liquid state at high-altitude, preventing vapor lock.
Buy real race like c112. I run in it my stocker and it has a real distictive smell to it. But beware you can get heavilly fined running race gas in your car. It has lead in it and the federal road taxes have not been paid on it.
Ah...so many pedestrians, so little time...

Seemed to dry out my rubber lines very quickly & the dye in the fuel would tint the rear of the car
If it's "tint" the back of your car, then the tuneup is off.
I have to disagree...
To the contrary actually.
I have been selling at my business and using race fuel since 1984.
I used to run straight race gas in my street cars for many years, like 15.
Myself and freinds have run it straight in our 2 stroke dirts bikes, straight in jet skis, chain saws, weed eaters and many different gensets straight. So I swear to you too much octane and lead ain't gonna hurt any kind of engine(non computer). Sure it might hurt your wallet, but not your engine.
You don't want to run leaded fuel in a engine that uses O2 sensors, we sell a 100 or 104 octane unleaded for those engines.
Now the great thing about race gas, is that it has stabilizers and other additives that help for it to last a long time, drasticly different than pump gas, exspecially ethanol gas. 
The reason I speak up is because it's wonderful stuff to store your car with. I store gensets with it and they ALWAYS start.
I parked my 360 74 challenger in my garage running in 1987 with straight 110 Turbo Blue which is a leaded race gas. I started that car about every 6 months or so, sometimes longer other times shorter until 2003. I swear, The car never moved or left the garage, I remember adding Turbo blue in 5 gal jugs during that time. It never failed to start.
Today I drive that car a lot with the same fuel tank, same edlebrock carb, same fuel pump, same stock original steel fuel lines.
That gas helps things like your fuel pump last and my rubber fuel lines have never suffered. Rubber hoses, carbs, valves, pistons all LOVE lead and racing gas has lead, just like the good old days.
So that's my take on it fron 25 years of selling and using leaded race gas.
Some guys didn't like smelling my dirt bike in the woods behind me, I told them then try to get in front of me?  Eventually they would be running it and keeping up!
Seriously after a few years when prices starting climbing we cut back to 50/50 mix in our sport machines and muscle cars.
And I have run many gallons of ethanol gas from the pump while we are out of town with the car driving it in extreme conditions, all with the same fuel system that was subject to 100% race gas for over 15 years.
Drove it to the top of Pikes Peak 2 years ago, it made it to the top with no problem with unleaded 92 gas in the tank.

.
and I didn't know high octane was hard to start in cold weather. 
), more octane than the engine needs could actually lower your HP.
