Tomorrow I'm changing the "O" ring on the intake manifold. Is there any other replacement parts necessary besides the gaskets I would need. This is the first time I'm doing this. Any tips?
Any other general information that might be helpful to complete the pull and replacement?

The manifold is very heavy, make sure you have someone to help and a plan as to where you will put it when it's off. Setting it on the fender, even with a cloth can damage the fender. As stated above do not turn the carburetor upside down or even on it's side. Leave it on the manifold and set them down just as they sit on the engine. Make sure you use a line wrench to remove the fuel line from the carb while holding the big end with a wrench.
If I remember correctly you do not have to remove the distributor on the Pontiac 350. Be very careful not to drop anything into the ports. If you do, get it out before you turn the engine.
Good luck Suzanne!

Are you talking about an O Ring on the Thermostat housing? As for any work on the manifold if you remove the thermostat you need to drain the coolant into a safe container otherwise it will leak out all over. If you will actually be pulling the intake manifold from the engine it is more involved and you need to get the surfaces of the intake scrapped very clean. Also the cylinder heads and the valley of the block need to be scrapped clean. I use RTV Sealer on the valleys of the block instead of the rubber seals you get with the gaskets. If you are just pulling the thermostat housing, scrape it clean and put the new seal or gasket on it. When you fill the radiator back up, bleed the air out of the engine block by pouring the 50/50 Mix of antifreeze and water into the radiator slowly. Listen for air escaping out of the system as you fill it up. If you trap air in the engine it will boil the water and cause over heating. I run the engine until the new thermostat heats up and opens to allow the water to run through the radiator. Then I check for water level and then replace the radiator cap. You will need to check the fluid level the next day after it HAS COOLED OFF and fill add some if it needs it.

Sounds like you've already got a lot of good advice, but just to add a couple things. A little grease works good to hold the gaskets in place while you lower the manifold back on, or if you prefer, gasket sealant. #2 (pliable) is the best. Don't make the same mistake a lot of people make by using RTV (the blue or copper stuff) with a gasket. Those are gasket makers, designed to use without a gasket, and as such don't bond very well to gaskets. So, joints that use them and gaskets tend to leak. RTV also breaks down in gasoline (not something good for the intake). If you happen to get your plug wires mixed up and have to re-install them from TDC, remember the firing order on a Pontiac is backwards from a Chevy.

Which o ring are you talking about(distrubtor) Yhen you just need to loose 9/16 bolt and remove distrubutor from the engine. If your chaging intake gasket make sure you change oil after job is done and you might watn to replace termostat same time. Gasket, tube of silicon,gasket scraper or round disk to clean old gasket. wd 40 for rusty bolts and do not force old bolt, you don't want to break any old bolts..

Its heavy and its awkward because you're woking with your arms extended and anything you do is going to make those gaskets move so things don't line up. Get a helper with good arms to reach across from the other fender. Some people have problems getting the spark plug wires back right . lable them with masking tape and felt pen. Good Luck

If there is a bunch of whoo-haaw to take apart to get to it, take many pictures on a digital camera before you start, because I would of been in quite the sticky situation if I hadn't done that when I rebuilt the carburetor on my '76 350 v8 Nova. I don't know if that will be necessary for your situation, but as you probably know carburetors definitely have a lot of parts.

Generally not. just be careful with the carburetor while your doing this. Do not drop it, turn it upside down, or let anything get inside of it or the engine either.
By the way... Nice car! My best friend used to have a sprint. He let it run with almost no oil and seized the engine, I'm still cursing the day he was born. :p

suzanne make sure you label everything and also put the bolts in seprate plastic baggies and label them also get your self a hans manual for that year and also have the correct tools for the job including a tourqe wrench aslo mark the dist. before you pull it out and label the spark plug wires for the correct firing order
