Don... tell your brother to put some fancy smelling race fuel in a baby food jar and when he needs a fix to open it and get his sniff... tell him to save his money and put 87 to 93 octane in the car.. he DOESNT need race fuel

I know that back when racing gas was cheap and easy to get back in the early '90's, I would put some in my 9.3 compression 440 and the car ran OK.
I did find that I had to reset the float levels in the carb though. The other thing I noticed was that the engine ran rougher and at a higher decibel with pump gas vs. race fuel.
Often I would fill the tank at the track with the lowest octane leaded race fuel and run the car. It was only a little more in cost per gallon at a U.S. track compared to what pump gas cost in Canada.
The car ran so smooth and quiet with race fuel that I could actually have a conversation with someone in the car. With pump gas there would be yelling back an forth. The benefits of leaded race fuel would last for several tanks it I topped off the tank with pump gas several times while driving it on the street. It seemed to work for a couple of weeks which proves that I only needed the lead or a minimum octane boost to keep the engine happy.
I wish they still made gas like that at an affordable price.
Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen!
Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!

Sorry for the confusion. I thought this was a thread about octane #'S, not - smell. I ( or someone ) must be on the wrong web sight. 
You came to the right place......lol
I actually started the thread because my little bro insists on thinking he needs 110 fuel in his 9.5 compression 360 n/a motor. I tried telling im it might negatively effect his performance, but he continues to run the stuff because he likes the smell of the stuff  crazy...yep.....but if I can convince him his car will run better without it, may wean him of it.

Why in the world wouldn't he go make a couple runs on 93 octane? He could even put a dash of grape fuel fragrance from Summit, smells like race fuel, I've used it a couple times for car shows and car cruises.
It's my little brother... He won't listen to anything I tell him.
Most of the time he just likes firing it up in his garage, rapping on the gas pedal, and sniffing race gas fumes.... Would be sad if it wasn't true
 
The smell of Cam 2 is very addictive, there is nothing wrong with your brother just because he likes to fire up the motor to get his cam2 fix,I have done it before and I am ok. 
Testing in California has shown that "breathing fumes from racing fuels may cause hair loss"....  
If you like drag racing, support your local track.

Cool, Keith. He has a little black 66 dart Gt with the factory white bucket seat interior. 360, eddies, 750 Holley, excellerator, 1/58 headers 904 and 8 inch. Weighs 3300 with him, all steel, no fiberglass. Cam is a way to big 258@50 solid with his low compression motor. Car sounds like a healthy super stocker in the water box. been 11.38 with it but no better since the heads were done

I have 12.5 compression with aluminum 72 cc heads in my street motor and run straight 110 Sunoco, though I think it could be a tad faster with 108.
When cats here mention 93 pump gas, do they really mean the actual 93 octane pump gas that comes from the pumps at the local Mobil, BP, Sunoco, Shell? If it is, I suspect many of you may at some point have problems stemming from all that ethenal that floats in the stuff. that is why I strictly use 110. I wouldn't put pump gas in my Mini-bike.
An alternative to this would be 94 unleaded and 100 unleaded Sunoco/VP I guess.
I use the 93 super unleaded they sell at my local BP,Chevron and Texaco. Have been for years and have had zero issues.
