I am trying to identify the intake manifold. It has a number 9 in the ID number area by intake 2. I could not find anything about this ID number in the olds information. Only an 8 and 10 was referenced. Thank you.
Carb. I researched the Rochester number and it appears to be from a Chevy. I would like to find the correct Olds Carb. Anyone know where I can find one?
You do realize that I answered your question three weeks ago, right? The block casting number is a 1968-1976 Olds 350. The intake is a 68-69 Olds factory 4bbl intake with divorced choke. Yes, that's why you need the correct carb, which would be 7028250 for 1968 or 7029250 for 1969. Of course, you also need the choke mechanism that bolts to the intake pocket.
Sorry Joe, I saw the picture but the intake had the number 8 where mine has the number 9. So is my intake the correct one? Also do you recommend someone who sells the correct carb for the car? Thank you.

Look again. The intake I posted a photo of has a large 9 and casting number 398663. It was factory installed on every 350 motor Olds built in the 1968 and 1969 model years. It is not original for a 1971. By the way, the 8 intake was a 2bbl intake, so obviously not the one I posted above.
I did not realize that 8 was two BBL and 9 4 BBL. I am new to this stuff.
And we're happy to help you learn. A rule of thumb is that if you ask a specific question (like about a 9 intake), the response will be to THAT question, not a different question (like about an 8 intake).
I did download the photo to my computer in JPG format. When I blew it up to view the numbers they became fuzzy (not enough pixels) so I could not tell if it was an 8 or 9. Thank you.
The heads have a 7 where the E is in your photo. The alternator is covering the other number. The next time I take off the alternator I will look at the other number. Thank you for getting back to me.

A '7' would be correct. Small block heads use numbers, big block heads have letters. So your '71 350 should have '7's.
Keep in mind the same head castings are used both sides so the driver side number is at the front and the pass. side number is at the rear.
Yes I checked both heads. The 7 is by the number 1 cyl on the driver side head, and the passenger side head has the 7 by the number 8 cylinder. Thank you for the info.
OK I am back with another question. I was able to purchase an Olds Carburetor to replace the Chevy Carburetor that came with the car. Next I purchased the solid line from the fuel pump to the carb. When I went to install it, it is off by about 2 inches. See attached photo. Is the reason for this is that I have the intake manifold number 9 for 68 to 69 Olds instead of the one for 71 Olds? And if so where can I buy one? Thank you again.
Looks like you got the hard line for a big block Olds, not a small block. The taller deck of the 400/425/455 motors elevate the carb relative to the fuel pump, which is why the BBO line is longer.
I just searched on line. You have to be VERY CAREFUL to check applications for some of these vendors. For example, Summit shows the same P/N fuel line fitting both Olds 350 and 455 motors. That should raise a big red flag, since the lines are different.
Fusick shows this one, but that appears to be the same P/N for the Right Stuff line that Summit claims fits both BBO and SBO. Summit could be the one who made the mistake in their listing, however:
Joe, That explains everything. I purchased from Summit. They also sent me an accelerator cable and return springs for a 71 Chevy / Pontiac. I have been trying to get a hold of them but no one is getting back to me. Looks like 60 dollars down the drain. After having a contractor rip me off for 27,000 dollars in 2013 I am getting very leery of ordering anything online anymore.
What about the Pontiac accelerator cable and return spring? How come Summit does not want to deal with anyone after they have their money? I just do not get it. My next step is to contact my credit card and tell them that I received the incorrect parts and Summit will not cooperate.

I can't speak to their customer service (or lack thereof). I've not had to return anything to them so far.
Does anyone have the length of the fuel inlet nut on the Rochester 4 bbl Carburetor where the fuel filter is located? Thank you.
Your 1971 carb should have the long fitting that accepts the 2" filter. The threads are 7/8" and the gasket goes under the hex. Later Qjets used the 1" threads and the gasket is at the very end of the threads.
I was finally able to purchase the correct fuel line. It is installed and the car starts right up. I returned all the parts to Summit. I am waiting to see if I will get a credit from them.
