Something around .500" lift should get you where you want to be. Even the old 509 lift factory cam has powered many cars to low 12's. I myself would go with a single plane intake. You don't need more low end TQ with a big 440 and a dual plane will only propogate traction problems. Any of them from the Holley street Dominator to the old ED Tarantula or the new Vic are all good choices with not much to choose between them. I like the new Thunder 800 AVS for some kind of decent mileage and the least amount of having to constantly screw it with it once you set it up right, but that's just me. I've had to make love to every Holley I've ever had the last 30 years on street cars. They leak gas constantly from all their gaskets and the DP's suck mass quantities of the stuff. Great carb for a race car, not such a great a carb for a daily driver street car, IMO. I've seen the 800 EPS carb almost match an 850 DP on the dyno with a built 440 (within 5hp) and seeing is believing. I'm sure the new AVS is even better. A cheap Holley alternative would be the old 3310 vac carb for under $300. It will work fine with the right jetting and secondary spring. That's the most bang for your buck with the least amount of car savy required in my book.  Again, just my  2cents:

schweet sure does give one a lot to think about...is there a reason most people run holleys?....i've been looking at getting a holley street dominator...i think i'm gonna get the engle K58 W/ 520 lift.....

Can't answer that really. The way they look? 

I had a new 750 ED carb on the 360 I removed from my car to put the stroker motor in and a friend borrowed it to try on his 70 Dart. The best it had ever run was a 13.09. 340 car with Performer intake, a 750 Holley with Pro-form parts, a Huges hyd cam of some kind and headers with the original motor with 80K miles. First pass was a 12.86 and he said it was just a lot easier to drive. Never did get it back from him. He paid me full price for what it & the strip kit cost me from Jeg's. It worked excellent on my engine too.

The AVS has the added benefit of an adjustable secondary opening point and 800cfm. There are really lots of carbs that will work just fine including the street dominator (though I've never used one of those..) so it's really a personal choice. The AVS would be mine today if I was buying something new for a driver street car, especially with gas @ $3.50 a gallon. I doubt anybody would dispute the AVS will get better mileage. I'm sure you'll be happy with anything you get, as long as it's new

thats great thanks for the info! lol i like the looks of a holley better but unless the air cleaner is off its not like you'll notice....so what makes mileage better? from the sounds of it i'd better check out a 800 thunder AVS correct?

[71chally416]

The AVS would be my choice. That's also what your engine probably came with originally, except the new ones are 100% better and flow more air. If you really wanna do it on the cheap look at the reconditioned ones Jegs sells. $347 for the manual choke version.

If you have to go with an Eddy carb use a Thunder , personally i get the best results with more tunable carbs like the Holleys & Proforms

[71chally416]

If every last hundreth is important I would go for a ProSystem carb if money was not an issue. They have winning cars in everything from Pinks all out to Pro Stock
and I've never seen any carb closer to being right-on when bolted to a motor. It probably takes a decade of racing and tinkering with Holley carbs to understand how to adjust and calibrate them exactly right. You can easily buy 2-3 carbs and $100 worth of calibration parts and gaskets before you find one you really like, so the expense of the custom carb is justified.

If it's a young guy starting out that's trying to do things as cheaply as possible, who
doesn't yet understand air bleeds, power valves and accelerator pump cams who just wants to bolt a carb on that will will work good, then the AVS is a safe choice. If the calibration is off he can usually get it in the ball park with a simple metering rod change that takes a few minutes and doesn't spill gas all over the Intake like a Holley jet change does. The secondary opening adjustment is even easier to do. That's my thinking on recommending a carb for this young guy.

750 Dominator 

[Chryco Psycho]

the 750 Dom is an awesome carb just poor intake & Air cleaner selection for them

[71chally416]

And if over $700 is what you consider a "budget" carb 

[black71]

thanks guys i sure appreciate it....i am wanting to learn the tuning tricks but would i be better off to get the eddy for now and master tuning on that then jump to a holley?

[71chally416]

If you get one and then decide you don't want it I'll trade you my Demon carb for it that made over 500hp on the dyno.

[black71]

hehe schweet  i've gotta blast and paint my jambs and engine compartment then its time to drop the motor in.....i did get the whole car painted but the painter did a horrible job so i getta start all over again!

[Chryco Psycho]

Holley style carbs have far more adjusability & tune differently to an Eddy carb so I don`t see an advantage to starting with an Eddy carb
