Hi
I bought a edmunds dual intake for my 52 thunderbolt 327 to enhance a rebuild ,I got it from a forum member
The intake came with a couple of stormb erg carbs ,aero s ,which I had rebuilt
It has a hot water circuit as the dual manifolds are noted to get cold because of the vaporized fuel mixture condensing on the walls of the intake and making for unreliable mixture
One y 's the hot water line from the I heater line from the water pump and y's back after the heater coil in to the head to make a parceled circuit ,this feature makes the edmunds systems desirable
I also got a 288 head and put this on for a compression hike
I ran a 12 v - gr system with a pertronix in the dist so I could run a hot coil
I used the 518 a conversion to get the overdrive
So what happened?
Don't know ,I over heat
Hmm
The radiator is recore ,the water pump and thermostats ,replaced hoses replaced the heat tube looks ok the heater core replaced and seems to circulate ,
Is it my dual carb set up ?
Ps can I attach phone pics?

I used a dual master that came with a booster that's larger than the one for drums from ABS the company that supplied all of the other hardware it was a generic system that the fellow and I figured would fit the fifty two
After a couple of pics went back and forth I sacrificed the driver side fresh air vent put a plate over the hole for some mounting real estate the supplied pedal dropped right down where the stock one used to be
I lived where there was a huge hill and had fade be the bottom ,now I live in driver maniac houston ,and am satisfied with new stop power
Abs supplies the parts that the other guys sell ,very helpfull you can look at thier catalog and figure out what unit would fit
Also manifold vacumb from the 327 was enough to run the booster

I used a power gen , a generator outside and alternated inside, they're direct bolt up , and switched the distributer innards to a pertronix system painlessly .the pulley I switched to the original one but it had "ford "stamped on it !

Hey maby the water outlet for the heater that I "y'd" to run a parrelel circuit through the edmunds manifold IS the overheat issue
It would be easy enough to block off the water tap and retry
Changing out the water pump ,replacing the hoses to the radiator ,replacing the thermostat didn't help , the heat tube . I withdrew it as much as it would slide back without removing the radiator amd it looked perfect ,a brass one not the corroding steel replacement
The heat tubes to the carburators are not installed maby the little chokes are in the choke position ,but the engine runs smoothly ,

I did the once popular 288 head on the 327 for the compression hike ,and am plagued with a mysterious overheat problem !
.radiator is record,hoses replaced ,I took out the thermostat ,I'll replace the water pump this weekend and maybe get brave and pull the heat tube but I replaced it before .
Could it be the 288 head. . ?

I still have the 327 head ,but I wonder ,an internal blockage ? Or a difference in the morphology of the head ? I'm mystified

I have a edmunds intake and it splits the radiator outlet to the heater to run through the intake too but I don't think this would overheat the thunderbolt ,?..
Can an ignition faulty wiring cause an overheat? What about lean carburator ?
Can I post a phone pic ?

Radiator defiantly worth a recore for the money ,if you want increase cooling you can put a high efficiency core in it ,you can take one of those temp sensors and shoot it at the radiator several places to see if there's shunting in it while the engine is running ,thermostat stuck? Or installed upside down? Radiator hose have a bend in it or. An obstruction ? How about an obstruction in the head From rust or gunk ?

Thanks for the thoughts
I was under the car yesterday and realized the mechanic had hooked up the pressure switches to the wrong pressure tap on the transmission ,according to the instruction sheet for the swap plus did some creative wiring not same as supplied diagram

I did a double swap ,the ultramatic to Chrysler 727 is a a popular mod ,
Then one step extra to the OD Chrysler 518
The 727 to 518 is popular also to get the OD and torque converter lock up so I went ultramatic to 518 !
Two switches run by pressure off of one tap (#4] each actuate sat a different hydrolic pressure
And are supplied voltage (12v)
The set up has a vacumb switch which will only send the power if there's vacumb which I borrowed at the base of one of the carbs
I'll go to 12 v to power the switches for the trans swap and re plumb to the propped tap the fellow used the #3 tap I don't know if this is actually different but I'll try to hook it up to the right thing and reassess

Is there a HEI distributer that would drop in to the thunderbolt ? I have a " early 8 cylinder delco system currently with a pertronix point eliminator
I think my overheat may have been a stuck thermostat, I took it out for now
And have crossed fingers

Hi I used a ultra torc 11 adaptor for the 727 then went a step further and put in the overdrive 518 so it has two pressure switches ( hydrolic)
The two switches lock the torc converter and
Put in the overdrive
They are 12 v neg gr switches
I used this module to isolate and sply the 12 v from my 6 v system
Www.6 to 12 volt.com they are for 12 v accessories like a sound system
I think ,my electrician hooked it up wrong
It's warm with the car off
Which in my book means it's got to be shorted ,
Alto the car didn't know which gear to be in in was hopping all over the place
Then I over heated and don't know of that was related or because of a new rebuild or what , ! Quite a day
So I thought I would abandon the converter and go to 12 v
So I could get a power gen , a new pertronix for 12 v neg
Take my packard starter to the starter shop?
Get a 12 v solenoid for it ,will it run backwards if it's neg ground.?

And resisters for the dash gauges . Then I can just power up the switches w 12 v and maby she'll fly

Hi ,for better or worse just put a Chrysler 518 a trans in my 52 200
It has 2 12 v electric switches ,that I tried to power using a module that supplied 12 v neg rom 6 v pos system it heated up today and the car didn't know how to shift itself
Hmmmm
So I'll maby go 12 v and skip the module
So this is probably an old issue for 6- 12 v conversion
I can get a 12 v neg power gen
A 12 v pertronix drop in and a 12 v coil
What about my starter?
Where do you put the resister for the dash ?
Also had a fresh rebuild now overheated
I had the valves adjusted
The thermostat works
the radiators recored
I replaced the heat tube
There's a 288 head
There's a 2 carb intake ,too lean and hot?

I just had a maiden voyage with my new power front discs I got out of Los Angeles wow these suckers are great!,, the thunderbolt ended up making plenty of vacumb to,pull the booster ,stock wheels fine
I think these guys make the parts that everyone sells in thier kits
Very satisfied
