Has anyone run this manifold?http://www.aaamarine.com/servlet/the-17 ... arb/Detail

There are people running this intake. Are you thinking about going this route? You may want to use the search button. Part number is 5041. Have a good one! Wayne.

Sorry I should have searched first.Just curious to see what the others thought of it on a stock motor.

here is not a link to a 2x1 setup, but something to consider about the 2x1 setup. there is stuff on the board about the 2x1, and some cool pics. i know, i have drooled over them. but i dont remember my search queries. good luck.

BOOSH!!!

Oldblue, no need to apologize. The key to the 5041 would be a matched set of one barrels. Slantsix Dan had some of these for sale a while back. You could also adapt (no big deal) a couple of small progressive Weber 2bbls and this may work as well. There is a good carb article in the article section on the home page. The 2bbl conversion that the link mentions would be easier. I have some extra 2bbl stuff , let me know. Also if you heart is set on the 5041 we can beat the price from AAA Marine.

Here's how it looks with two progressive 2bbls on custom mounts and all the rotating rod linkage cut off/filed down

Cool.Thanks for the pics.How is the mileage compared to the one barrel?Would a single progessive get good mileage on a modded one barrel manifold?

I think that fuel distribution would be poor trying to feed 6 cylinders.
If I remember correctly there is a write up in the articles page (go to the home page and there should be a link to Articles)

Edit:

Sure enough, Josh wrote an article on carbs. Here is a quote from the article regarding progressive carbs.

"The staged type of 2 bbl gives us the best hope for improving mileage and power on a stock slant 6. These carburetors usually use a nice small primary venturi for low speed use that will give good throttle response and economy while having a larger secondary venturi for increased power when needed. This type of carburetor is common on many 4-cylinder engines such as 2.2 Chrysler products, Pintos, Vegas, and Rabbits.

A Slant 6 Club of America member in Sweden used a Weber 32/36 DGAV carburetor on his Valiant wagon. He went from 19 highway/15 city to 22 highway and a little less than 15 city. This is in a wagon with 3.55 gears so you may do better. He reports "a definite improvement in torque" and "with a heavy foot the acceleration is much better than with the old carb". He blames this extra acceleration power for the slight loss of city mileage. He also used an adapter to bolt this carb to his 1 bbl manifold so power should be increased further if this carburetor was mounted on the 2 bbl Super Six manifold. You can read more about it in issue 54 of the Slant Six News.

Another route to go if you have a modified engine would be the Holley 2305. The 350 cfm version should do quite nicely on a mild engine. The 500 would only be for more heavily modified motors. The 350 may sound like its only 40 cfm smaller than the Holley 390 cfm 4 bbl, but it isn't. Holley tests its 2 bbl and 4 bbl carburetors differently. They use a 1.5" of Hg (mercury) pressure drop for 4 bbl, while 2 bbl carburetor flow numbers are generated at 3" of Hg. So the difference is actually much greater than the 40 cfm that the numbers indicate. There is a formula to convert between the two, but I don't have it handy. One other thing about this carburetor: It uses annular discharge booster venturis that give a better metering signal. This lets you get the jetting closer to optimum without suffering bogs and hesitation. If I can stand to part with the money, I may try this in place of my 390 4 bbl to test the results. If not I'll try a Holley/Weber carburetor off of a Pinto or Vega.

Update! The Holley 2305 is no longer available. They didn't sell well and were discontinued.

I did try a Holley model 5200 that is nearly a direct copy of the Weber 32/36 DGAV. It even says made under license by Weber in the float bowl. The carb I got was off a 1980 2.3l Ford Pinto. It had an electric choke that made installation easier on my modified '66 Dart. This carb was a disappointment on my modified 225. I expected better low-end torque over the 390 Holley, but I lost torque. It also had a nasty bog if I opened the secondary too soon. The accelerator pump that works for a stock 2.3L was inadequate for a warmed up 3.7L This would probably be a good carb on a stocker as was the experience of a Slant 6 Club of America member, but my engine didn't respond well."[/i]

I'm not running it yet but its on my bench waiting for a second carb. i have two b series GM carbs but they are to tall. If any one has a line on a pair of stock carters..one barrel Im looking. does any one sell after market one barrels?? ....i have a slant six 62 lancer 225 and love it

I may have a matched pair of brand-new (not "remanufactured") 1bbls; send me a PM if interested.
