This has probably been discussed a hundred times but wasn't having much luck with the search feature so guess I need to ask. I'm working on a budget 505 inch 440 wedge build. Was thinking of getting the 440 source stealth heads and now looking at a Torker II single plane intake on Ebay. But I've got a stock 70 six pack setup and wondering if staying with the six pack setup would be as good or better than the Torker single plane? I'm looking for good torque below 4000 rpm so which is best? This would be in a heavy b-body, 70 Satellite with a 727. Probably like to keep the gearing around 3.23 or 3.55. Thanks!

That's what I was hoping to hear, basically that I could expect as good or better torque numbers than the single plane. Got to get the carbs worked though, it's been on the shelf a long time. Any advice on the linkage?

From the sounds of it, its a street car... put the 6 pac on and dial it in... it will make more low end torque for the street.... plus you have it... I never cared for the 6 pac due to the hassle of setting them up... as for linkage, go with the same style they came with

If it was on a 440 i would say six pack but since it is on a 505 you will have to really work to get the six pack to run right and it will just be easier and cheaper with a single carb.
In the 1/8th with my 493

Then i went roller with ez heads and ran 110mph with the last setup

Since it's a street car torque from off idle til around 5k rpm was my primary concern and as you say I already have the six pack with what I'm guessing are either stock carbs or direct replacements. It's the manifold and carbs on my 70 gtx and been sitting for a long time on it's original six pack engine so I've got to go through them for a rebuild anyway. Since the gtx probably isn't going to get restored for awhile thought I'd just "borrow" them for this hot rod I've been working on.

I was looking at a Torker II on ebay this afternoon for around $150 but doing a little searching around on different websites it didn't appear to be that well liked. I was seeing more compliments for the Holley Street Dominator and Eddy rpm manifolds as far as torque was concerned. I had a Torker on my old 440/4 spd 72 gtx way back when and it didn't seem like it ran like it should have but that's been 30 years ago and my memory has faded a little.

I have ran both type of intakes on several different motors, if your staying with the stock size 440 intake ports use the sixpak and take the time and effort to dial it in to make it work like you want it to  The stock sixpak Holley outboard carbs are way to lean from the factory  Also a lot of them will either stick the ouboard carbs shut or open to quickly causing a bog. I have, and you can to, fix those problems, time and effort and maybe some money spent on parts and tools to modify the stock carbs  BTW, the Eddy Torker 11 440 intake is a slug, stay away from them  The Mopar M1 single plane or the Eddy Performer RPM are a lot better, 20+ HP and more torque gain than that on them compared to the Torker 11 on the same day and the same motor and with the same carb. with no other changes. As already said big C.I. motors like a lot of air, the more air the better Use the parts you have(6 pak) and spend that money on some other parts you need There are a lot of 6pak naysayers on here as well as in the rest of the world, once you get them(the sixpak) dialed in they will show the cars behind you, with the stock type single 4 barrel and single plane intakes like the Torker 11 set ups, your tailights in a heads up acceleration contest   More air, more power

Great info, thanks! With the six pack setup I like the idea of using what I've already got, leaves some money to spend on a few other things. Biggest single 4V carb I've got laying around is a 800 DP Holley. So what can I expect from the six pack setup after rework, 950 cfm?

hah no need to do that. Mine worked great right out of the box. I've adjusted them like I would any other carb. Intake and carbs are stock and pulls to 6400 w/o any issues.

but you have a 440 right? see what happens when you stick them on a 505, will you just crank that little screw on the side of the carb to feed it enough air to idle?

Don't worry about the CFM numbers What you will get from a decently set up sixpak is mind numbing torque and HP Make sure your rear tires are up for the task in front of them   The last dyno testing I did with a sixpak compared to a well set up Holley 1050 CFM Dominator on a good single plane intake with 440 port size headed motor made the exact same torque with both intakes, the sixpak set up made 8 HP more than the 1050 Dominator did I have dyno tested a bunch of different pump gas B and RB Mopar single four barrel motors of all different C.I. sizes and several different BB Mopar motors with sixpak set ups on similar prepared motors, all the six paks made peak torque at or below 4600 RPM and they made peak HP at or belwo 5800 RPM on the dynos In my bracket car all the six pak motors ran faster shifting them above 6500 RPM, as already mentioned The sixpak motors ran faster at the track than the similar 4 barrel motors did So if you only rely on dyno testing and don't take the parts to the 1/4 mile drag tracks in the same car with no other changes you will never know what the real world results are at the track when comparing single four barrel motors with a similar equipted six pak motor My first .060 over 440 sixpak blueprinted pump gas iron headed motor only made 470 HP, it pushed a full interior street 1970 Challenger 4 speed car with a 3.54 Dana gear and a set of 275x60x15 BFG drag radials to mid to high elevens through the muffs on CA pump gas It made more torque than HP also but I didn't focus on torque numbers back then so I don't remember exacly how much torque that motor made now  I built myself a 512 C.I. 400 block pump gas street stroker motor with a Eddy stock 383 sixpak intake with a set of stock 1970 440 carbs modified by C&J Engr. in Whittier,CA it had a set of midly ported 906 heads on it so it didn't flow a lot of air into that motor, that combination (9.25 to 1 comp. ratio) ended up making 612 HP at 5600 RPM and 644 Ft lbs at 4500 RPM on CA pump gas 8 yrs ago Sixpaks and strokers rule  I used to help a freind race a bracket 1968 Roadrunner, it started off with a Eddy 440 Torker intake, not the later Torker 11 ,and a 750 DP Holley, we switched that car to a stock 1970 cast iron intake with stock 1970 CA spec. Holley six pak carbs with no jetting or modifying them. That car picked up .15 ET and almost 2 MPG with the intake and carb. change only We switched it back later that summer and the car slowed down exactly what it had picked up earlier in the year

yes stock stroke 440, I guess it would depend on the rest of the build, unported stealth heads, mild cam and 505ci probably... however my next build will be 500+ci w/ a couple of whisltes, so the six pack will go on the shelf.
