I Run Vp Red Race Gas In My 70 Road Runner. I Heard Of Additives That You Can Buy From Sonoco And Vp To Raise Gas Octain By Mixing With Regular Pump Gas Is This True And How Are Others Driving There 12.1 Engines On The Street With Out Race Gas. At $10 A Gallon Im About Ready To Sell My Mopar Cant Afford To Drive It Anymore.

You can mix your fuels from VP, or drop to a mixture if Turbo Blue or Torco, Even Track Tek at around $300 per barrel, 50/50 or even 40/60 and cruisin' your ride would be a lot less costly. You could get the cost of fuel down to $3 per gallon. VP is good fuel but way over kill for anything you need. You'll need twice as much alky for the conversion and it IS hard on part's. It eat's everything.
E85 could be the less expensive answer. There is a larger initial investment, but i know that here it is less $$ than regular lawnmower fuel. And there are so many plants being built now that the fuel is not going away.
For years, TOLULENE was the main ingredient used to raise octane in fuels. It still works. A gallon is about 10 bucks, though, from your local hardware store.

I don't know how ethanol effects output in a normally aspirated engine. I know you need more of it. I turbocharge everything. E-85 would allow me you run way more boost and make more power. We just don't have any pumps here available to the public.

Any Ethanol added to gas will lower the total fuel's BTU's (energy)
The more % of Ethanol in the fuel the MORE you will need use to make the
same power as streight Gas. Don't confuse Octane being higher with the
amount of energy the fuel holds. That's a simple way to explain it. Hope that
helps shed some light on this E85 VS Race gas theory.
You'll need to run some HUGE jets in the carb or alot larger of a injector and
fuel map if it's injected. Don't expect to pull up with a gas tune and fill the
tank with E85 and have a monster... just won't happen. "Might" not hurt
anything but I wouln't chance it!
Anytime you change a fuel you'll need to change the tune. This is a bit more
tedious because of how different the fuel is.
I'm off topic.. well kinda... IF it were my Mopar I'd drop the compression down
to 10.0 or under if it's Iron heads 11.0 or under if it's Allum. Thicker head
gaskets or different heads will get you there... Doesn't Indy Cyl. head or
Edlebrock make a set for your car?

I Could Change The Pistons For Lower Cr`s. But , This Car Is All Origonal. My Mom Bought It In 1970 And Its Never To This Day Been Broken Open. The Starter,alt,belts And Hoses Have Been Changed The Trans Rebuilt But The Engine Has Never Been Tamperd With. I Still Have All The Paperwork For The Car. So Changing The Heads Are Out. I Found A Place That Sells Blue Tek For $8 A Gallon Thats $2 Less Than What I Was Spending On Vp Gas.
re: high compression engines
One thing to also remember is that the high alcohol content is hard on some parts unless made for it. It likes to eat things like: the inner coating of older gas tanks and fuel pump diaphrams. Your safest bet would be to lower your compression. If you don't want to keep the high compression heads you can sell them to offset some of the cost.
good luck

I have a high compression 427 in my truck.It runs fine above 4500 feet on 91 octane and stock jetting with 12 degrees initial timing.I live in Ely Nevada altitude 6435.I run an Edelbrock 750 carb on a Edelbrock tarantula high rise manifold.When I take the truck off the mountain I have to change to smaller metering rods and put in the silver springs so it runs in the rich portion of the metering rods at the slightest acceleration and on top of premium gas I add a 1/2 gallon of Toluene or xylene(Lowes caries Xylene $16 a gallon)to boost the octane.I have a 2 1/2 gallon gas can I pour the xylene in so I can get it in the tank without spilling it down the side of the cab.I have a 15 gallon gas tank.I have to back the timing down to 4 degrees and the vacuum advance timing limited to 16 degrees.It was allot of hassle to find this set up but detonation will destroy a good motor in a hurry.I plan to get a snow performance water/methanol injection set up so I can recover the power that detuning the engine this much takes away from me.Not to mention what a hassle it is to carry a timing light and make all those changes in the parking lot at the gas station 1/2 way to Vegas.
