Hi all, I'm a new member and I'm new to the forum. I'm trying to restore my 1973 Sedan Deville and I'm looking for diagrams for the engine vacuum system and also for the HVAC system. If anyone can share it I'd greatly appreciate it. Thanks in advance.

This car is beginning to cost me a fortune!  :(

I'm trying to do it right - this is my first foray into auto resto and I never anticipated just how expensive it would get! I want the car to last, and I want it done once and done right! The problem is that I feel like every issue I uncover and attempt to rectify begets 3 more...  :o

Matt,
I would guess that the total "investment" in something like a 73 SDV when it is at the stage of say a #2-1/2 driver would be in the neighborhood of 10-14K. With that as reality, you can go from there.  It is normal that many of these vehicles were not well cared for during the last few years of their active driver hood, so normal wear and tear will most likely be throughout.  That said, when complete and in a "dependable" state, these cars can offer years of pleasurable driving.

That's what we call "creeping elegance"!

I agree with your methodology, do it right, do it once, be done with it and then......enjoy!

Only real issue these days (for me anyway) is the quality of parts available.

Keep us posted on what's going on with that beast.

Thanks for the replies and I will keep ya's updated! What I want to do with the car will take me a while and cost a decent amount, but I am thankful the body is straight and (mostly) rust free. I really want to get as much power as I can out of the 501 block!

500, not 501.
The trick I "try" to use is to pick 1 project at a time. Get it dependable and then work on the spit and polish.
Also, when you pick a project, study it in detail because while you have something torn apart you may be able to get to something else.
And as suggested above, be sure you have a manual.
Good luck-and post some pictures!

The standard motor for a 73 would be a 427 cubic inch motor.  You can if you like, spend a few extra bucks for a little more power. This is the 511 inch motor in my 73.  If you want this you had better stop worrying about the cost. LOL.

"500, not 501."

The cause of much argument and confusion --- the stock engine in his '73 IS a 501 series engine --- of 472 cubic inches.  The 501 series 500 cubic inch engine could be found in the Eldos and later in the rear wheel drive Cadillacs starting in 1975.

Mario,
It looks like I am entering the four stages of senility.
1. you forget names
2. you forget faces
3. you forget to zip up
4 and finally you forget to zip down.
