Holley 2300 tech specs

farmall57 I think my carb is closer to the 1710. If you look at the picture I posted, you will see that the bottom of the venturi is 1 1/2 inch wide. Which matches more with the 1710. I honestly believe that I have the 275 cfm model. I don't live above 7,000 feet. I live in the central valley of California. We do have most if not all gas stations in my home town that have gas with 10% ethanol. So is having the 60 jets ok or should I get a renew kit with the correct jets. Also I noticed that the metering block has a four digit number stamped into it. The number is 2325.

The .060 is big for a 304 and the 275 cfm mixer. It will be overly Rich and that can be bad on rings etc. If you are running a stock 304 and e10 you could run a .055 main jet and still not be lean..
Running the .052 mj on my 304 and it runs perfectly on pump fuels. More is not necessarily better.
 
Since the Holley spec book shows the #60 jets for the 1711 and #53 jets for the 1710 the 1711 has to have something different in the venturi, I'm thinking it must have the larger venturi size.
 
So am I going to be safe running it on my stock 304 with the 60 jets? If not then where can I find the 55 jets for the e10 gas?
 
The 1 1/4" venturi is in the 'g' series 2300 carb. You don't have the 'governed' carb. Just a plain 2300 275cfm carb. Living under 2000 ft elevation, the #52 main jets should work well, as has been suggested. The main jets can be purchased at a speed shop or maybe you can order them from your local napa store.
 
The ethanol additive won't damage the metal of the jets. The central valley of CA appears to be mostly under 400 ft elevation. There isn't much 'down' from your location. Use a 'low restriction' air filter element in the filter housing, if you have the 'dry paper' housing on the engine. Look at the k&n e-1100 element. A bit taller than the stock IH element, so it 'lifts' the lid above the housing base and allows much better breathing for the engine.
 
I'm not worried about the ethanol hurting the metal. I'm more worried about the jets getting clogged. My home town is around 81 feet about sea level but I do like going to the mountains ever so often. I don't have a air cleaner for the 2300 yet because I'm running a 2210 on my 304. Which has quite a bit smaller air cleaner opening then the 2300.
 
The ethanol fuel 'by itself' won't clog the jets. Clogging a main jet happens when there is no filter in the fuel line, allowing trash to pass from the tank to the fuel bowl of the carb.
While the mounting circle of the air filter housing is different for the different carbs, the 'filter element' should be the same.
The #52 main jets shoud be ok up to ~ 5000ft but the lower air pressure will start to be noticable at maybe 4000 ft. That is why the need for the higher air flow filter element becomes important. That e-1100 element lifts the lid off the base allowing air to reach the filter through the 'gap' around the lid as well as through the snorkle.

When I get a air cleaner for my 2300 I'm going to go with one from eddlebrock, Holley, or some aftermarket one that's open all the way around. If I do go with a more stock one that's fully closed except for the snorkel. I'm going to connect tubing to the snorkel to get more fresh cooler air into the carb.
 
The 'aftermarket' air filters will only supply the heated/expanded air from the engine compartment. The main jets in the carb will be 'sized' to provide the air/fuel ratio for that 'expanded' air at the elevation of operation. If 'cooler = more dense air' is supplied to the intake system, the fuel ratio will become more to the 'lean' side. Depending on the elevation of operation, this more dense air supply May require a larger main jet size to bring back the fuel/air ratio into a better balance.
