440 HC, coil and ballast resistor

Post by hlequippe »

Hello,

I have had my Int III for a few months and want to take the opportunity of the summer months to do a bit of clean up of the engine bay.

1- My Ballast resistor is located on top of the engine between the carb and the distributor.

This seems a odd place to me as it is getting very hot in the engine bay envy more hot in this location. Shouldn't it be placed elsewhere ? Am I wrong in thinking that too much heat might impact it ? Thanks for sharing the locations of your ballast resistor.

2 - I have a strange coil on my car, it is big ugly and yellow. on top of that, I have not seen any brand or model on it. Anyone has any idea ?

Hervé

If its any consolation to you, that ballast resistor get A LOT hotter than the ambient air in its immediate vicinity, so I would not worry too much about relocating it as it won't make much difference to the ballast resistor. I would worry more about those two exposed terminals. Better replace them with FULLY INSULATED terminals to avoid causing an unintended short circuit.

As for the coil, yes that is an uuuuggggly one. Just remember that a coil is not just a coil. Generally you get coils suitable for electronic ignition (low resistance between + and - terminals) and then you get ones typically more suitable with points (higher resistance). If you do replace it with another, be sure to replace it with the correct type. I don't know which one would be suitable for your car. Hoping others will know.

Another thing I see in your pictures....

It looks like there is a fuel filter strapped to the coolant hose. If that is the case.... Now the fuel is being pre-heated by the coolant pipe as well as by the hot air being sucked through the radiator. Fuel being delivered to the carb should get there as cool as possible to minimise evaporation while in the float bowls and when the engine gets switched off. I suggest that you re-route the fuel delivery hoses to the carb to minimise heat exposure.
Best regards

BTW, what intake manifold is on your engine?

I think I see something else :D

Is there a rectangular opening in the radiator shroud below the right hand fan?

Thanks Philip,

I did already reroute the fuel hose to make it further from the collant pipe and I changed the location of the Fuel filter as well.

From what I can see on the engine, I have an Edelbrock Intake Manifold with a Holley Carb on it and an Edelbrock Air Filter. I have plans to replace the Holley with an Edelbrock 650 CFM (1806 is the reference if I recall correctly).

Another priority is to recreate the missing air deflector around the radiator. On another note, my car is a very early MK III dos it still has the MK II radiator brace.

Per your question, I have 2 fans with a slight offset for the rectangular format of the rad. SO I do have some empty space on the top left and the bottom right.

Why not go back to the original Carter? I believe the Carter Thermoquad is a MUCH better carb than either Holley or Edelbrock, the main reason being that it is so much easier to tune fuelling (no extra needles or jets needed, just a small screwdriver)

Please note that the fan shroud should not have any openings in or around the shroud, otherwise air will get sucked in via the easiest route and not through the radiator.

Another question then,

If I want to replace my points distribution to an electronic distribution, what you you recommend ? Id did that on my Triumph and it was one of the best modification I ever did to it

Here is my view of the rad at it is today, so I definitely need to work on the rad shroud on all sides of the rad

Morning Hervè

I have a friend wirh a Jauar E-type V12 and he uses the "Lumenition Performance" kit which also has voltage and dwell compensation. It works very well all the way to 6000rpm on his v12 and will thus do just as well in the v8.

Please note that you also need the bits that fit inside the distributor.
Best regards

The FF that has been entrusted to me for some attention, also has a fan cowl setup that limits air flow to the diameter of the fans. Its better to have a Mk3 cowling where the entire radiator core area is exposed to air flow when the fans switch on.

Philip, you asked the question about a Carter Thermoquad. Well the main reason is that I have never seen one advertised for sale new. On the other hand, I can get an Edelbrock 650 CFM 1806 for less than 500€ all taxes and Postage paid.

I have a friend with a Chevrolet Corvette who has an Edelbrock on his car.

With respect, Herve, I would rather go for a used, serviced (or even better service it yourself!!) Carter TQ than a new Edelbrock. There are excellent youtube videos on how to service the TQ.

Having said that, the TQ would only really come into its full right AFTER it has been tuned with a WIDEband oxygen sensor. I believe I could tune idle and primaries without the WBO but secondaries can only really be SAFELY tuned with a WBO.

Here is my car before being tuned: https://www.youtube.com/watch?v=Bp_7qpwbc9s

And here it is after I tuned it: https://www.youtube.com/watch?v=L8iLbZo-Er0

Philip,
The coil in the first picture is an Accel "super" coil of unknown vintage. They are oil filled. I have had these fail on street driven vehicles. A standard coil is highly recommended for reliability. At a minimum I would mount it vertically to avoid leakage and self destruction (mfg instructions state this in slightly different terms...)!

I just had my coil fail. I had relocated it under the fuse box. When I looked at it it was stamped MOPAR Made in USA. Obviously original. I have a 74 Drophead. Replaced it. All is fine. NAPA premium

I will definitely replace that ugly Coil and put a more standard one. In any case, it is standing where the AC compressor should be and adding back AC is one of the longer term (and costly) project I have for my Interceptor. I actually ended up finding on the Mopar parts catalog http://www.mopar.com/assets/pdf/catalog ... atalog.pdf" onclick="window.open(this.href);return false; the same coil as mine (Page 113) referenced as a high Performance Coil
