400 cooling and oil pressure issue

Ok fellas,
I very much appreciate everyone’s input so far. The fan blades are about 1” 1/4 from touching the shroud but yes you are correct when I was measuring some of the distances the edge of the fan blade was very close to being flush with the opening of the shroud.

also my vacuum advance does lead to not being plugged into anything.

I will pull the air cleaner off and get better pictures of the fan spacing as well today.

 

Ok fellas back to the question of timing. I ran the car till it got to about 170. Then I hooked up my gun. At idol in park with the vacuum not hooked up is 7.8-8• at 580rpm.
I hooked the vacuum into the carb where in the picture it’s been plugged my rpm shot up to 900’s and the timing was 31-32. I tried my best to take some pictures of the fan clutch distance. Again 7 blades at about 6” long from yesterday. I don’t know when I took the car in for a/c to be rebuilt if they replaced the fan clutch with something different then when I had the motor built and installed in 07.
I do have videos if someone knows how to post them. Or if anyone is willing to take my number or give me their email. As you can see I’m trying hard to figure this out. I just don’t have the knowledge.
Thanks Guys!!

 

Vacuum advance in hooked. The line doesn’t show on picture but on video it lines up with the 0 at 8•

 

With vacuum advance hooked up to carb where in picture it had a plug on it.

 

Just showing you temps and gauges after about 20 minutes of running and not sure what the hose is for the air cleaner that isn’t hooked up as well as distance of fan from radiator

 

The name or reputation of a place is only as good as the employees inside

 

Thank you Larry. So keep the vacuum hose connected to the carburetor and turn the idol down some. And I can also attach a T to connect the hose from the air cleaner, the vacuum advance to the carburetor plug I pulled off. Basically run those 2 lines together into the carb.
Thanks again much!

 

Ok Larry I got everything hooked up. I took some pics to give you an idea what I’m playing with. The vacuum advance is T to the air cleaner then to the carb. I did very very slowly get the carb to (I hope I was adjusting the correct screw) get the idol to come down. I pretty sure it’s the right adjustment screw because a half turn shot the idol to 1100 from 970. But backing it down seem to take a lot of turns. In the picture I attached I turned it 7 turns to the same position. I ended up with my idol after running the car for a bit in the drive way again at 570-600rpm and 9.8* timing fully warm. It wasn’t that warm of a day here to run it around to see if the temp will creep up. I just thought it was odd that I started the car hooked the timing gun up and the last hose to the carb and it was running at about 870-900rpm and the timing I did not check but would have assumed it would still have been at the 32 degrees that I showed. And as I backed the idol down my timing is right where it was with no vacuum advance or air cleaner hooked up.

 

Also I’m probably due for plugs. I just bought some ac delco R44TS until things get figured out with tuning it. Should I get iridium plugs or platinum plugs? There is msd wires that look fine. The plugs were wet and dirty when I pulled one to see how they looked.

 

No, don't use iridium or Platinum, just a waste of money.

 

I'd consider going a heat-range hotter than the ones that were wet and dirty.

Agreed. Fancy plugs don't make sense when used with carburetors. ESPECIALLY true when the carb isn't tuned properly, and doesn't have a mixture-control solenoid and O2 sensor for feedback.

 

Thanks fellas!

 

Thank you!

 

Correct. My timing did not change. So I have an edelbrock intake manifold. There is nothing there for me to hook up a vacuum line, or hasn’t been put if there is a way. So I went from the canister to the carb that had a plug over it and then the top of the T is the largest of the 2 connect points to my air cleaner.

If this helps. I did notice that when I had the T from just the canister to the carb. I put my finger over where the hose would interconnect for the air cleaner and the idol shot up BEFORE I adjusted the idol. But when I connected the air cleaner hose it dropped down some (the idol). Then I began turning down the idol.
This is where Initial connected the vacuum canisters to when I gave you the 9* disconnected and 32* degrees connected but it was a one way from there. I did the exact thing but added the air cleaner into it. I’m using 5/32 inside diameter vacuum hose.

I will double check nothing got pulled off

 

Let me rephrase this. My timing is the same as it was with none of the vacuum lines hooked up as it is now with the vacuum lines hooked up

 

I'm pretty sure that the vacuum connection you show in the pictures, on the side of that Holley carburetor, above the base plate, is a "ported vacuum" source. If you want a "manifold vacuum" source. there should be a similar looking port that connects to the base plate part, under the front float bowl.

It looks like there is another vacuum line connected to the manifold source already.
