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..
A boat, a GMC truck, some Craftsman Tools, LOTS of Zombie Protection, and a few Goldfish..
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...
