1969 Imperial progress thread

[Big_John]

That is what I love doing. Unfortunately, it is more of a curse than a blessing most times. I learned that trying to get someone else, you have to rely on, to match your standards is not fun to do. It will take more time, but I will finish this project in a way I will be proud of eventually!

There are "only" two financially big things still on the Todo list (besides a lot of small things which will sum up too of course) ...
The engine and Interior (I’m going to try and reuse the vinyl from the door boards, but the seats have to be completely new.)

I decided to do the Engine next, because I can do more things around it then when doing the seats first.

So next thing will be getting all the engine parts into the hot tank and then to the machine shop.
The machine owner will also help me picking the right parts I will have to buy to do a proper rebuild on my engine.
I will post the finished list of parts on here as well when I have it to get opinions from you guys as well.


So last week, I started engine work by removing all the dowel pins and expansion/pipe plugs and then grinding away all the casting flashes on the block.
Still ways to go with that, but the temperatures dropped into the negatives in my shop again...

All of the dowel pins were stuck in the block so I had to weld nuts to every single one of them in order to attach a slide hammer to them to get them out. But in the end, that worked just fine.

Are you planning on resurfacing the engine deck? That's the only reason to take those out.

Be careful with what you replace them with. I've seen guys snap off hardened deck pins, so I stick with the non-hardened pins like original.

Yes. Thanks. Something still not right. Appears I have no cam to move it. I took it loose and ran the motor and manually connecting the points did nothing either even when the switch was turned off. I tested the switch and it's perfect according to FSM but I still have 1 speed and no park. I'm going too order a rebuild kit and try that. I think the gear is the problem.

there are different styles if internals on these motors. Maybe you have a mix match of different versions?!

Gear and Cam are both different.

I think the machine shop is going to resurface the block, yes. That's the plan at least. but they will measure everything and see if it's necessary.
I pulled the dowel pins no matter what, so they don't have to. Machine shop time is expensive.

I'm planning to buy new pins from 440 source. They don't say anything about if they are hardened or not. But I will ask them. I have a list of questions for them anyway. Thanks for the tip!

Thanks. Mine looks like your 69. It must be the cover switch or wiring. I found the speeds. Dash switch must be grounded. Still no park.

When you move the wiper switch in the "off" position, the rotation of the actual motor is reversed. The big white gear then moves in a way so that the slope cast into the white gear moves a lever hinged to the cover to a more inward position. This lever then gets caught in the hook which is attached to the cam on the output shaft. The cam then moves the output shaft excentrically thereby elongating the travel of the wiper linkage, allowing it to move the wipers down into the park position. This movement stops when the pin cast into the cam opens the switch located in the cover, interrupting current to feed the motor running in the "park" direction.

If the park stop switch is bent open, the wiper won't reverse, so no park. The wipers will basically stop at whatever position they are when you move the switch to the "off" postion.

On the earlier wiper motor models, if the grease is old and chunky it might keep the hook of the cam to move outwards, so it is not caught by the lever mounted to the cover, resulting in a contiuous movement. On the newer type motors the same can happen if the spring pushing the cam outward breaks.

Note that the cover has a small metal tab which must be set into the correct detent cast into the wiper motor housing. Which of these locations is the correct one depends on the body line as the three speed wiper was also used on B- and E-bodies. For a C-body, it is the upper one.

Another Thread is very informative on wiper motors.

You are my new F'in hero. Great work.

I tried to repair mine. Cleaned everything, replaced bad wires etc, not as nice as yours, but cannot get park to work no matter what I try.

FIXED. I kept putting the cover back on with the switch on wrong side of center post

I dropped my engine parts off at the machine shop last weekend and talked with them for 3,5 hours about what my goals are and which parts I should buy.

My stock cast iron heads are junk, so going with aluminum cylinder heads is out of question.
First I wanted to go with the 440 source Stealth Cylinder Heads, but the engine builder didn't like that they have the same general combustion chamber design and spark plug orientation as the OEM heads. Apparently, it’s a known problem of the OEM head design, that the spark plugs don’t reach far enough into the combustion chamber which results in a suboptimal combustion.

He recommended the Trick Flow PowerPort 240 heads since they have a way better design. They are almost twice as expensive, but I will go with them anyway.

Further he told me, that he had too much trouble with flat tappet camshafts in the past few years. Apparently, the quality of flat tappet camshafts nosedived for a while now... Because of that, he does not offer to use them anymore. I was planning to go with a hydraulic roller setup anyway, so I am fine with that.

Initially, I was planning to use the 440 source Bushed Stainless Rocker Arms, but he talked me out of it, because it’s not necessary for my targeted RPM range. My OEM stamped steel ones are in excellent condition and just fine, so I plan on reusing them.

I hope I can reuse the stock rods as well, but that depends on the final bore size and the resulting compression ratio. Maybe it will be necessary to increase the stroke a little bit.

I had the vision of a “Sporty Luxurious Coupe” since I started my restoration. So that’s the goal.
She will still be a cruiser, but I want to have a little more power available when I want a little fun.

Below is a list of parts I am considering right now. Any feedback, recommendations and general input is much appreciated!

Because one cylinder has some rust, I don't know the final bore size yet. So, all the related parts are just placeholders for now, until I know the final bore size.

You’re continuing the excellent level of detail and craftsmanship that is aligned with the Imperial name!yummy!
