Does any one know anything about it. I've seen them on the old school dragsters and want one in my 1965 Barracuda. I need to know if they make them and maybe a link to find one. Just the basics.
My 340 is built. If you need to know how built I'll tell you.

Thanks
 
As in single bbl carbs? I don't know of anyone that makes a sb manifold. you would have to get an injection stack manifold and make the mounting pads. And tuning would be a pain. So would the linkage. And you would have to get much smaller jets or you would flood it out.

not sure about 8 singles........ are you sure there not 8 stacks for Hillborn injection?

How about 6 X 2 bbls for a 440!

How 'bout 4 4bbls on a 426 Max Wedge?

Just remember that the more carbs, the less vacuum signal. That means the cylinder has to suck in air from a small space and not from a large space like a 4 bbl manifold.
Works great on an all-our strip motor but runs like crap lower in the rev range.

think the same as you here!
i seem to remember from some old hillborn (i would gues from the early 70´s) catalog i looked in where i work that they actualy had stack injection for smallblock mopars in there catalog back then, but i doubt they sell those anymore, since i cant imagine the demand for mechanichal injected smallblock mopar stuff is very high but i gues you may be able to find one used for a pretty large sum of dollars, and then you will have a ton of work to set it up to work properly but not impossible and it sure would be damn cool seeing!
sory if this is to far oftopic
 
I have done this with fuel injection on a VW engine with good results. I have witnessed comparative tests with Weber carbs, the EFI does much better with HP and response. See :http://www.aircooledtechnology.com/kitcarlson.htm You might be able to use the throttle bodies from the early T1 2.2L mopar 4-cylinder turbo cars. They are fairly inexpensive since some upgrade to the T2 manifolds and TB. There is a www.TurboDodge.com forum, you could WTB the TB in the classifieds.
 
Or you could possibly make a custom manifold. But either way you are looking at a pretty big hassle.
 
agreed, MAJOR hassle. i had enough trouble setting up two dueces on a chevy inline 6, although once i figured it out it ran GREAT. 8 carbs should only be used on nostalgia drag cars and wild show cars that don't need to be driven. and if you do manage to find a manifold, its probably going to be 8x2, not 8x1.
If your handy with the TIG welder, you might be able to fab some kind of sheet metal manifold, but again, is it going to be worth all the time and hassle. IMO, not. but it would certainly blow peoples minds at the cruise nights.

The 2.2 turbo cars were all multipoint injected. There were the early throttle body injected cars from 83-85 non turbo with a single butterfly throttle body but that system sucked out loud. It was total garbage, I don't see ever getting eight of those junkers to work all at once on one engine in my lifetime.
 
See I don't want to do the 6x2's b/c I've heard that it leaves some cylinders starved and i don't want that. 2x4 is just to generic for me. I don't have a hemi so i can do 4x4. 8x2 would work but i don't like the elongate-ness of the two's. I like blowing peoples minds so... I know how to Tig but getting the welder and everything. I'll talk to a guy. I think he knows a guy that might be able to cast one for not too much. The guy he knows made a set of custom 400 pontiac heads for 300 each.
Thanks though.
If you got any other ideas i'm listening. Any thought is progressive.
 
You can get custom made individual stack electronic injection for just about anything these days. I can't remember the name of the company but I saw the ad in National Dragster a little while back.

Casting heads for $300? Well maybe if you work at or own the foundry but machining them is the spendy part.

Personally I think stack injection is the way to go on this, electronic stack injection that is.
 
If you're sure you want to do it the easiest way would be to take something like a performer rpm airgap manifold. then cut the runners off and leave the base and water crossover. Then weld custom runners onto where you cut the runners off. I think four webber carbs would work better, one side per cyl. Inglese induction does a lot with them so you would be able to find stuff for them.
 
I know exactly what you are talking about. I have been on a similar search for the last 2 years and the closest thing I could find was a old 4x2 manifold for the old poly small block. Also been looking for an old Hillborn style injection system for a smallblock. The ones I do find are expensive for worn out junk and only 1/2 there. So my solution was to have a guy cut me some manifold flanges on a CNC machine - out of 1/2" steel plate then plane them flat. I don't mind the hassle of welding up the runners and a plenium (if I go that way). But they want a fortune for Stromberg 97's or equivilent. D'lortos and Webers are too much $$$. So now I am looking to modify an old mechanical CIS injection sytem (port) to look like a Hillborn. The idea someone mentioned about cutting an aluminum manifold is food for thought. If you find something of interest let me know and I will do the same
 
You used to be able to buy them in kits that you had to weld yourself, they are called "log style" intakes. They are easy to make yourself, the only thing is finding or making a good set of flanges. I would love to build one for my 360!

And they never made one for a small mopar, just big blocks and Hemis

I don't remember where I saw it but a guy was putting three carbs on his slant six and he used the carbs off a late 80's escort. He said you could buy them brand new for like $40. I'm pretty sure it was on one of the slant six forums. But they were small and would help carb signal.

is this what you are talking about?

LOL Exactly only a 65 cuda not a I don't know what that is.

You guys are helping a lot. The EFI idea i have thought about before but i like carbs a lot. not for proformance but for looks.
