The conversion kit for a Holly is $130. The problem is they don't sell a 2bbl kit. You wind up with enough parts to do 2 2bbls. The shops that do a bunch of them only charge you for half of the kit and use the other half for the next guy they do a conversion for.
A Rochester is just bigger jets and some labor to enlarge some passages. You would have to talk to a shop to find out the cost unless someone here has had one done and will pipe up with the price.

Unfortunately I could not make the rules meeting but regarding B-Mods but it is my understanding that the B-Mods and Factory Stocks are going to alternate between Belleville and Tri City. If so I personnally am going to run at Brownstown or montgomery county because I am not going to be changing gears to race every week. That's crazy, if Belleville and Tri-City want to work together like that have one class run Tri -City and the other class run Belleville. that would make better sense. jmo

The problem is the tracks don't understand e-85. Folks all I every ran was pump e-85 in my crate. Lead big show at tri city till I screwed up couple years ago. Won features against some of areas best with pump e-85.. While other guys where running high dollar crate fuel.. I watch Adam kick run e-85 all last year. He never over powered anyone or out horsed cause of fuel. What's funny is the tracks think the other guys are just running pump gas!!!
Not much price difference in 93 at pump and 110 from home service oil in a drum, buy it by the drum and saves a lot of money 110 at the pump was only 5.75 gal last yr so you spend $10 more a nite e85 is not even available at any pump til June summer blend before that its e70 you have to mix it anyway and monitor it, been there sometimes its good sometimes it's really bad and done right its work

Where are you getting 110 for 5.75/gallon?
St.francois county or get on home service oil deal they sponsor over 200 cars and you get fuel basicly at cost or buy vp110 for 400 a drum maybe little more this year and it will last 10 nites we only burn about 5 gallons a nite in a Ss at granite and you can mix with pump gas and make it last longer .2 championships in a row with pump gas and 110 gas now and then works good
If you are having to enlarge some passages on the Rochester, isn't that making it an illegal carb to begin with?

No. He's only talking about passages that meter fuel, booster discharge hole, main wells, jets, air bleeds and emulsion. You could change these areas to calibrate the carburetor to work with any reasonable fuel yet the carburetor would still be tech legal because legality is determined by measuring the size of the areas that influence the amount of air flow through the carburetor.

Bingo. Thank you.
Any reputable carburetor shop (C&S, Jet, etc) is altering the sizes of the fuel passages in a circle track Rochester to run properly on regular gas too. That is what you are paying for when you buy one from them, adjusting the fuel passages that aren't adjustable from the factory unlike a racing Holley. If you recall, a lot of these carbs were manufactured during the gas crunch of the 70's and weren't exactly calibrated for performance. They are a 2bbl by the way. They were meant for economy. If this was illegal, at least 75% of the carbs out there would be breaking the rules.
The rules are intended to limit the airflow of the carb not the fuel flow. Actually by increasing the fuel flow by approximately 20% for E85, you are displacing air in the venturi and effectively reducing the airflow.
But then again, who's going to check the sizes of the internal fuel passages in a carburetor. And where would you find a list of all of the factory specs that were manufactured 40-50 years ago anyways.

B-Mod drivers we thought this was a great idea to rotate the 4-Cyl and the B-Mods giving the B-Mods another track to run at and putting something neat together for the 4-Cylinders.
After reading these posts and the negative remarks. Wondering if this still a good idea to run B-Mods at Tri City.
We are rotating B-Mods & 4-Cylinders. Bell-Clair is rotating Micros & 4-Cylinders.

Haven't seen many negative comments Revin. Think it's been a pretty good discussion of positives and negatives of e85. Think if more people where educated on e85 that it might change there minds.. Everyone thinks it's a big hp jump like alcohol.. It's easier to test e85 then any other fuel.
