Which Carburetor?

I have a 79 Dodge Aspen R/T with 360.
.30 over 360 around 10:1 compression
202 heads with a lot of porting and 2.05 Chevy intake valves
a mechanical cam with 236 duration @.50 lift
1.6 roller rockers
A Mopar M-1 single plane intake
A 10" 3000-3400 stall converter
Manual shift valve body
4:10 gears

I use this car for high performance street driving, about 50-100 miles per month. I would like this car too idle somewhat and be very fast when I nail it. I have tried a few stock Holley carburetors and I can`t get any of them to idle or accelerate for sh1t.
What would you recommend for a carburetor? I was looking at the Barry Grant "Speed Demon", "Mighty Demon" and the Proform 750 Double Pumper.

Yes those are all good, I think Demons Suck and Holley's are great too, but both of those talk forever to fine tune and get the tuning you want. If I was going to get a good carb, I would go with a Edelbrock, they can match you up with a Carb that will give you what you want. Personally I think their great. No tuning envolved.

I agree with Fyter, but as I suggested in another forum, take your ride to a local dyno shop. I became a believer when an aquaintance took his 502 GM Crate motor, and for $300, they rejetted his Edelbrock, Set-up his distributer, and got an additional 40 HP out of the thing. Oh yeah, and as far as your idle, I haven't known many big cam, single plane engines to idle very well. Great at high RPM, but usually a challange to keep running at the Drive-thru.

Any carb will provide what you are looking for, the key point is to take the time needed to jet it correctly. No carb is a bolt-on-and-run.

I personally prefer Edelbrock carbs, very simple and yet ultra reliable. I have an extensive set of instructions on my website on how to set these carbs up and maximize their performance potential. There are 3 seperate sections, read them all to gain the most benifit.

On an engine built to this level of tune, a cheapy-chugger isn't going to make it. The E-carbs are great for little bittly engines or low-RPM engines. The E-Q-Jet is a GREAT carb on the big Chevy.
What you really need is an AED 750HO. AED (Advanced Engine Design, Richmond, Virginia) takes the "good" Holleys and modifies the curcuits to get the best air/fuel ratio across the entire flow range. If you supply enough information about the application, they are capable of delivering you a carb that really is "bolt on".
As for the BG stuff (Demons, et al), I looked at the Barry Grant pro stock while at Indy last month. Holleys... Go figure. Don't buy the hype, and NEVER fall into the trap of "cheaper must be better". It seldom is, if ever. There are certain brands of high performance parts that have been around FOREVER (in car years). Some are "brand X" (Mr. Gasket, Accell, Holley (manifolds) Weiand, Doug's, etc.). Others are brand "A" (Hurst, Hooker, Edelbrock(manifolds and heads), MSD (a relative "new comer"), Mallory,
Holley(carbs). If you go to your local track and study the winners, you'll find the vast majority stick with brand "A". Go to an NHRA or IHRA meet, and you'll find 99% of them with brand "A".

I respect your opinion but completly disagree with your belittling comments. Yes in the competative ranks of NASCAR, NHRA, etc a performance worked Holley will provide about 5% increase in HP over a Street Holley or Edelbrock, but in street trim no one could tell which carb an engine uses unless they looked.

Each manufacturer's products has their unique advantages and disadvantages, yes the Holley advantage is slightly more peak HP but has the disadvantage of lower reliability. The Edelbrock sacrifices a few HP for that reliability and drivability, it is the owners choice on where their preference is. Thousands for big and small blocks modified to all levels successfully use both Holley and Edelbrock successfully.

You bring up a very good point that the Q-Jet is a fantastic carb and should not be overlooked as a contender, they provide a great comprimise between power, reliability, and fuel economy.

The main problem with any carb is that there are very few people who really know how to jet them correctly, and correct jetting makes an unbelievable difference

Volvord, they aren't "belittling" comments. They are statements of fact from some of the best carb people around. Holley makes more p[ower. Period. Rochester makes a more dependable and efficient carb than any of the other OEM types. The Edelbrock "Carter clone" is a difficult piece to get "right" . Most tuners have better results with genuine Carters. You must remember, AFB "technology" is nearly 50 years old, and has had precious few refinements. The Q-Jet is 40, but has had numerous refinements and enhancements over the years it was produced. Holleys are an ongoing project...
I don't sell any of the carbs. I advise, and my customers make their own choices.

If you're running a 360 with 4.10 gears, don't use Edelbrock.
