Thanks Russ, all.  I am gonna have another person, I know take a look at it. He is more familiar with older cars. I will keep you posted if I need a new manifold I will let you know

Rick, these engines are high compression, unless it was shipped overseas as a low compression engine.  The engine VIN stamp will have a special character in it.    

I have good intake manifolds for alot less than 400 bucks, please email me at russ@thecadishack.com

Hi Rick,

     If your present intake manifold is slightly cracked/leaking, the replacement manifold you buy will probably have an internal choke tube (about 10 inches long) that is clogged/corroded.   Ask about that internal choke tube.  Removing the clogged tube can be difficult - don't want to crack the used manifold you buy.  That tube controls the heat flow to the automatic choke and critical for the choke to open properly.  Just trying to help with your purchase.

Okay thank you Russ, and I agree with earlier comment about the nice job on yours. I was impressed by many of the pictures.

I’m not a mechanic and I am learning about this compression stuff and all that. After over two years, I finally got my 63 Cadillac back.

The carburetor needs some adjusting stalled at light coming home running rough at low idle and the mechanic is not quite getting it and admits. it’s not his field of expertise

as far as the compression they cannot get it above 15 putting a tester on the intake manifold.  Victory engines who did the final assembly believe these were a low compression engine, and that a booster would likely be needed if the brake pedal was to be improved much.  After installing and running the booster he discovered the manifold was leaking so now I am looking for a replacement manifold, I just seem to be able to find complete assembly at 400 bucks

The choke tube is not associated with intake vacuum. If it is, there is a crack in the intake allowing that to happen.  The choke tube runs through the exh passage so the fresh air being drawn in is heated for the choke assembly.

Hi Wayne.  Rick Yasenchack here.  In your picture "vacuum lines B4, the copper  line going into intake manifold-did this just side into mainfold without any fitting?

I'm thinking this is a source of low compression to the brake booser

Wayne,

     These are some before and after pictures!  You did a lot of great work on this car!
