Out of Gas
#1
Gas gauge is not working currently so never knew how full or empty
the tank was.  Drove the car around on short trips.  Started the other
day and after about five minutes the engine stopped running.  Cranked
a few times, a couple of hits then nothing.  My mechanic stuck his
finger down the carb and came back dry.  Cool!  Empty tank.
Don't drive the car that much and only short trips so the gas has been
there for awhile.  Good to get it gone.  The engine, D0AE Cleveland,
has less than 5000 miles on it.  My mechanic wants to put some aviation
gas in it, 100+ octane.  You can take a jerry can to the local airport.
Probably need to retard the timing a bit, may to 6 degrees?
What say you?

Tell us about the engine!
I’m building a rowdy stroker 383 Cleveland right now so would love to hear more!!

With 100LL you can advance the timing, more octane provides more anti-knock. With lower octane you have to retard timing.

I don't see why you would want to retard the timing if running 100+ octane? The higher the octane the less prone to detonation. I will on occasion go down to the only place in town that sell race gas and put about 5 gallons in (place looks like a car show on Sat am during the summer). I always bring my tools with as I can advance the timing a little more with the race gas and have some real fun.

Very high octane gas is not really needed and can add to the heat in an engine. When I worked at lawn equipment factory out model shop ran lots of engine tests in hot and cold room situations. If you put high octane fuel in an engine it burns hotter for sure.
If you have a Sunoco gas station near you they usually have 90 to 100+ octane gas also. One here even still has leaded gas. Here is link to search for close one to you. https://www.sunoco.com/find-a-station
Lots of stations keep the no ethanol fuel here due to the number of older cars running. I think I pay $3.25 / gallon at local Citgo for 90 non ethanol. I also add StaBil and Lucas gas additive. https://lucasoil.com/products/fuel-treat...-treatment
My engine is a 351 C bored .050" over with cam and 4-V with 2-V heads.


When a man is in the woods and talks and no women are there is he still wrong??

One of the Dutch gov great minds future law idea is to give no less than €1500 / $1681 fine to someone running out of gas, if it's not due to a mechanical cause...
Currently it's a bargain as it's just €230 / $257...

The consensus is to advance the timing when using higher octane gas.
Currently set at about 14 to run California 91(?) octane E10. Runs pretty
good at 14. Go to 103 octane, no E, where would you set the timing?
Engine also has some kind of cam, not stock.

I would just try it at the 14° for a couple of days, so you get a feel for how it's running, and then try it at 16°. I don't know that I would go more than 16°.
