I am looking for an early Six Pack "Mechanical Set Up" these were fitted to certain Cars but of which ones in particular I am unsure, I do have a manifold for a 383 and a 440, so this is not necessarily needed although I would take it if a Seller does not want to split them,but he 3 x Holley Mechanicals is what I am looking for please.
Thank you for reading this :p
Grant :p
 
You have two manifolds? The 383 and 440 intakes don't interchange. Which engine are you working on? You won't find a factory "Mechanical Set Up" for these engines, they all relied on vacuum outboard carb operation. Why not stick with the stock set-up?

This is for your Jensen, right?

Hi Photon ;-))
Yes I do have 2 engines, I am working on both, I have a 383 and a 440, I also have 2 x six pack inlets, 1 for each the 383 and the 440,
I am looking for the earlier Mechanical set up but I wasnt sure what cars they were on, but it looks although Dave was aware, I just fancied have the mechanicals to bring the outboards in with the centre one from the beginning rather than waiting for the Vacum Outboards, I feel they would be more Adjustable, I guess I would need to advertise on a Ford Forum Photon, and yes they are for my Jensen, :))
Thank you for you interest Photon ;-))

Ford, I think had a manual setup previous to Chrysler's vacuum outboard setup. Not sure but I think one just sold on Ebay although listed as Mopar..........

Hi Dave yes that looks like them, thank you, so it was Ford that had them was it? would you know which Fords or which engines they were fitted to Dave please so I can narrow my search maybe?
Thank you also DAve :))
 
70 440-6 4-spd had mechanical carbs

Not on my GTX, or my old Charger r/t, both 1970 440-6 4 speed cars.
I didn't think any mopar six barrel ever came factory with mechanical linkage that I know of, of course I could be wrong.

Mopar did sell them through Direct Connection and all three carbs had accelerator pumps and the center had the choke, popular upgrade for racers in the 70's, and they are completely different carbs than the vacuum ones.

There is linkage that "converts" the vacuum carbs to mechanical also, but I think that was aftermarket type stuff, not sure what you have to do to the vacuum pods so that they don't interfere. Also if a setup like this is used, my understanding is that opening the outboards manually without accelerator pumps on them it will just bog and never work correctly.

Either leave them vacuum or get the ones with accelerator pumps on all the carbs.


here is a pic of the aftermarket linkage

there never was a mechanical 6-pak carb system from the factory. there was an aftermarket set-up that could be bought at speed shops in the early '70's. i had one of those mechanical set-ups on a 383 back in the day. drove good, easy tune, but really killed the torque off. vacuums are the best for street use. corvette 3x2 carbs work very good on a 383 but may require fuel line and linkage hook up mods. if i had to have a mechanical set-up i'd probably try a pair of 500's for outboards and a 350 center carb.

good luck
 
those ford carbs are very small. probably flow a little less than the Demon 3x2's which are only 750cfm at best.

Oh I see, I know TMP Carbs do a 3 X 500 cfm set up dont they Lew,I believe they are sort of reduced CFM's due to Annular Boosters which bring them to about 1350cfm which should be about right but I am not really a Carb Man just love Triple carbs, do you know anything about them and how they would perform on a 440 Lew?
Its only really a Standard Type 440 but built new and fresh with about 9:1 and stealth Heads, the cam I used was a Mildish one the same sort of profile as in an "E" series 383.

i don't know anything about TMP carbs. i would caution you to be careful about buying something "modded up to fit". cfm numbers for 2bbl carbs are mostly marketing hype and aren't real. i still look at venturi area/throttle bore sizes rather than relying on cfm numbers. the best suggestion i could give you is to use the factory vacuum carbs. the factory vacuum carbs will work on the 383 and work very well on a 440, plus all the brackets are easy to get. i've used the mopar vacuum carbs on 383's and 440's and feel they are superior to the aftermarket 6pak mechanicals in a street/strip car. i believe the vacuum carbs will average more torque over the entire power curve. the corvette carbs are vacuum and work very well on a 383 but have the fuel lines on the throttle side and automatic kick down linkage is an issue.
 
Ok I was referring to GG's white book that shows mech. carb conversions for 70B 4-spd and their numbers. So maybe not? I had a set of these years back and have seen several sets over the years. I've known of the aftermarket ones but didn't think they had the same numbers?
Course I'm a pinhead and left my white books in a motel a few weeks ago.
 
Grant, I'm curious, not trying to sway you.

Why do you want mechanicals?

Have you considered doing vacuum secondary's?

The only reason Dave was I was under the asumption they were more tunable/adjustable should I say. But looking at all the reports then maybe I am swayed Dave :))

Thank you Lew, then maybe for the 383 i will go for this, bearing in mind I dont have the Quick down issue asI have put a a 5 speed Stick Shift in the car now Lew, so do you know what model corvet or carb set I am looking for from a corvet then Lew, I do already have a Tri Manifold for the 383 you see ;=))
Thank you again Lew ;-))

Than kyou anyway for your input Mark ;-))
