Post subject:  New to the Group.
Hi, I'm new to the group and I just wanted to introduce my self my name is Hutch and I have a 69 dart with 225/6. I purchased the car a few month ago and I am happy with it, I just need some advice on how to turn it in to a reliable daily driver. I have replaced a long list of parts on the car already. I have replaced the radiator, spark plugs, wires, cap,rotor,air filter, ballist resistor, msd ignition, alternator, starter,ect. What would be some other good things to replace or repair and how would I go about getting a 2bble intake? thanks for the help, Hutch. :)

Welcome aboard, Hutch.

Did you change the thermostat and hoses when you replaced the radiator?
How do the fan belts look - frayed, cracked, glazed?
What about the brake pads/shoes?
Might go ahead and change the fuel filter and check the rubber fuel lines for cracks - don't forget the one back there on the outlet from the sending unit.
Make sure battery terminals are clean and tight.
Does the heat riser "flapper" under the intake manifold work properly - opens and closes smoothly?
All bulbs burning brightly - inside and out?

Just a few things to consider,
Jerry

thanks for the ideas. I will check on those things. The fuel filter is good I changed that and the battery also. As for the heat riser what does it look like? :?:

Or things to add to the car to make it fun and more safe to drive... front & rear anti-sway bars and good shocks are always high on my list.

Image

The rectangular hole at the bottom / center of the above picture (exhaust manifold) is the heat riser valve-
(of course mounted in your vehicle you won't see this view)
but the round disc, to the left of the opening should move freely back and forth a half turn or so-
which operates that 'flap' in the opening...
If you remove the air cleaner, the round disc is a couple of inches below the carburator towards the front of the car-

And that flat shiny thing between the manifold and the round "counterweight" is a spring which, when heated by the exhaust, expands and unwinds, causing the "flapper" to close and block the opening. That redirects heat away from the bottom of the intake and out the exhaust pipe.

The shaft that everything pivots on runs through the walls of the manifold. Over time, it can rust up and seize, rendering the flapper non-functional. MOPAR used to sell a high-temp lubricant to use there, I don't know if they still do. The pivot points also wallow out, causing exhaust leaks. I'm not sure, but I think I remember seeing a MOPAR repair kit to fix that problem, too.

Ok I found the heat riser "flapper". Now I need to know how it should operate and how it should be hooked up if done propperly. If anyone has a diagram that would be great or knows where I can find one. Right now it moves freely but I think it is not hooked up correctly. Thanks for the help Guys!! Hutch

Not much else to be said about how it works. If it rotates freely and springs back to the rest position, you're good to go. There are small diameter pins protruding out of the manifold on each side of the heat riser. The one on the round counter-weight side is there as the anchor point for the coiled spring I mentioned. On the opposite side, away from the counter-weight, there should be a pin with a small spring stretching over to the end of the flapper's shaft. I believe (?) it's only there for anti-rattle - I can't see any other purpose for it.

Does your manifold have the round counter-weight like in the picture? If not, it will have one of some other configuration, but it will be there, nonetheless. Sometimes, the small pins may rust and break off, thereby disabling the coiled spring. :evil:

It's a different type of counter weight. The peoblem I c is that it looks like the spring should be hooked to something and it's not. It moves freely but I still wonder if it is functioning correctly? :?

both types of heat riser valves...

If the spring is not hooked to a pin, it won't work. Work the counter-weight by hand and see if you get any resistance.
