Your cam looks good, you have enough exhaust duration. Your compression may be a touch high, ive heard of people running alky at 16-1. I wouldn't hesitate to try it. Im at 14.8-1 now.. I dont do anything in between races. except put more alky in trailer and in the tank to warm car up the next week. Come winter time i drain system, put a gas carb on it, and run the engine on gas with fresh cheap street car oil until it gets hot, with some antifreeze in cooling system, then drain gas and back valves off, done. Unless the engine is going to be rebuilt, then that is not needed. Also take the alky carb apart and spray it up for the winter. biggest down side to alky is the amount of alky you have to bring to track and store. we usually get 4-5 drums couple times a year. We have 2 cars tho. our other car is a camaro, runs 5.40 with bbc, rear mounted cell with magnafuel 500 for a pump. no issues, been 8.40s with it 1/4. | |||

C-14+ Don't waste your time with that engine on alky. If your busy towing your car around, then step up your game on a better cooling system and a 16v battery. strangemagicperformance.com oldsperformanceproducts.com WD dealer for just about all your performance needs. | |||

This is coming from a guy who never accomplished anything in drag racing. You couldn't get your car to run on alcohol so you gave up and went back to gas.  Worlds Quickest And Fastest 71 Cutlass On The Planet Earth | |||

I'm just gonna focus on the last part. I have seen this way too many times, people don't give alcohol a chance. They bolt it on and expect miracles and won't put in the time or effort to tune it correctly. No 2 engines are alike and no 2 fuel systems are alike. Rarely will you just bolt stuff on and go racing.

So very true. And most people don't do the things that really make alky work well. Many don't want to consider injection. some have no interest in a vacuum pump. Or a pan heater. Or changing anything about their at track practices or at home maintenance. Just pour alky in the tank and and give up when it doesn't work on the first pass. Alky is faster and cheaper than race gas in the majority of bracket cars. There are a few combos that are very refined that simply work better on race gas. And there are some big block heads that require different cams to make it work properly. But the majority of regular builds like Alky a lot. Foxtrot Juliet Bravo | |||

Why run on alky? my shytbox over weighted digger engine runs .983 on the 60ft and 200 up top with a 6.7 et, normally aspirated, cast manifold and a single carb with no oxy fuel at all. Now tell me once again about your alky? strangemagicperformance.com oldsperformanceproducts.com WD dealer for just about all your performance needs. | |||

I have never understood the “alky is cheaper” mentality. Yes alky is half the price, but you burn twice as much Last year I ran two cars on alky over the course of 2 big racing weekends (8 total races) and burned through 3 full drums of alcohol, 165 gallons.... This year on gas I burned 70 gallons. I spent the same amount on fuel | |||

Sounds like you need to work on your tune-up and technique when running alky. maybe the carb builder?? We've burned no more than 9 drums from first part of april until last weekend at the world finals. that's with two cars and running when its 40* out on couple weekends. its almost 1-1/4 gal a run pending how much warm up and how big track is to where your pitted. And there has not been very many off weekends, and most were more than one day weekends. | |||

The same could be said about your gas set up if you gained that much when you switched! If a motor is optimized and efficient it won’t see those kind of gains. As far as carb versus injection...same deal! If it’s a god carb and tuned properly, it will be as fast if not faster than injection. I had two of the best carb builders in the industry build me a gas carb and an alky carb...gas was almost 30hp better and made more torque...and we made multiple pulls with each and fine tuned both. I’ve also unbolted a toilet and bolted on a carb and they ran the same. All comes down to how efficient the combo is.

Here i am, Mr Strange Magic, Mr know it all. I come to tell everyone that alcohol is bad for your engine. yuk yuk yuk  Worlds Quickest And Fastest 71 Cutlass On The Planet Earth | |||

I went to alcohol in 98 and it was really simple. I put a Product Engineering fuel pump in my car with a rear mounted fuel cell and #10 line all the way up front to the regulator. Took a 9375 dominator and had Avanti convert it for alcohol. Bolted it on the engine and went to the track. The best the car ran on gas was 9.98/10. flat. Off the trailer it went 9.68. Captain know it all who thinks he smarter than everyone else decided to switch but would`nt listen to me on choice of carbs. Him being a Barry Grant ball washer decided to use a Barry Grant gold claw POS with McClintics dual needle and seat bowls. His car fell on its face every time leaving the line. So ever since then, he`s had nothing good to say about running alcohol and its all because he`s a failure at it. Worlds Quickest And Fastest 71 Cutlass On The Planet Earth | |||

When I switched to alky, I never saw twice the fuel consumption. Even with a toilet. I know everyone says you burn twice as much. And yes under full power, you do. But how much time do you run under full power? The same people who say you burn twice as much complain that their oil is full of alky as a rule. The volume difference really shouldn't be that much. I'm EFI now, and I burn even less. I really don't care what others use for fuel. I'm just trying to understand why some have the intense hatred for alky. Foxtrot Juliet Bravo | |||

Same here with EFI. My SBO i drove to the lanes and back to the trailer with a 3 gallon fuel cell and still had 60% fuel left over. Now with the 706 i tow to the lanes and back to the trailer and only use 1/4 of a 3 gallon cell. Worlds Quickest And Fastest 71 Cutlass On The Planet Earth | |||

$170 a drum for alky, $485 drum for gas. Simple math really .......... | |||
|
| DRR Sportsman |
2 drums of alcohol per one drum of gas needed. 340 dollars versus 485 is 145 dollars saved running alcohol 2-3 oil changes per 1 oil change from alcohol to gas is also a difference I’ve ran alcohol for 90 percent of my racing career, carbs and injection for 2 decades... after the switch to gas I’ll never go back | |||

With my 68 Nova @ 3000 pounds with the 540" BBC, EPD heads and sheetmetal intake with a birdcatcher on top and injectors at the base of the intake, making 1100+ Hp. I never ran out of alki fuel with a 5 gallon fuel cell, bracket racing driving from and back to the pits. And only needed a few squirts of pump gas for the first start up of the day. | |||
