octane booster?
I've got a 1977 F-250 with a modified 360. It needs atleast mid grade to run good. I was wondering if it would be cheaper to buy regular and throw in an octane booster or just buy midgrade

Well you know the price of gas in your area ? What is it $5 or So a bottle of octane booster to treat 14 to 18 gallons of gas? And the Hassle of making sure you always have a bottle or 2 on hand when you fill up on Regular.....
Or not worry about it and always use the midgrade!! With My 521" Cobra build..Istead of buying some 110 or 116 Performance gas to mix with the 93 Octane.. I'am going to use an Acetone Mix..To bring up the octane....Hell of alot cheaper than race gas..And plus it really keep the system clean!!

First of all I want to know what you did to increase compression in a 360! This has been the $10,000,000 question on this board for quite a while. We would be forever appreciative if you could enlighten us on this.
Next, octane boosters commonly claim an increase of 2-3 points. A point is 0.1 octane. So if you started with 87 octane and applied the booster, you'd end up with 87.3. Not a big deal.
Acetone has the potential to work better, but beware it eats rubber! I dont know in what ratio it would, but it is some nasty stuff, beware.
I'd just buy the premium. Most effective.
Edit: If I have some gasoline I want to keep good over a long period of time, I'll mix a gallon of Acetone with a small bottle of Marvels Mystery oil. Then, mix this with gasoline at about 5 ounces Acetone / MMO mix per 5 gallons gasoline. It keeps the gas good for at least a year, when I change it out. This is in my electric backup generator, which doesn't get used much. I'll also run the above mentioned mix in equipment in which I want to clean out the carburetor. Keeps varnish from building up.
