ID Intake/Carb
A couple years ago I bought a VW and after talking to the seller he threw in this intake manifold and Quadrajet, saying it was off an Olds 350. I tucked it away in the trunk of one of the Cutlasses and didn't give it another thought until I decided to swap a 350 with 2 bbl into my '70 and figured a 4 bbl would be much better.
Is this an Olds 350 manifold? What application is the carb for? (PN 17057250 1317 APT)
The carb is clean inside and everything moves freely so if this combo will work on my 350 I'll rebuild it and swap them over.

That is a SBO intake and that carb is newer than the manifold. The carb is from 1977 and the manifold is pre 1973 (I think) due to the lack of an EGR valve.

Like Randy said, the carb is a 77 Olds Quadrajet.
It is a good design and can be set up to work well, just needs a little work. It has the larger primary bores and internal APT which can be modified to be adjustable from top.

You got the best of both worlds, later 800 cfm carb and early non egr manifold. Hopefully the carb moves freely and is cleaner inside. Buy a quality rebuild kit and clean it very well. It may be on the lean side, depending on what it is off and what is going on. My late 70's Holley reman carb had 71 primary jets, 44k primary rods, M hanger and CV rods. My 78 403 carb was the same except 73 primary jets and an I hanger. If it has similar to my 403 carb, it should be very close. I thread a plug where the aluminum plug is tapped into the airhorn. Then I slotted the APT with a hack saw, then it can be adjusted with a small flat screw driver. I gained a few tenths at the track adjusting it. Just count the number of turns from seated if you do remove it and modify it.

Thanks for the info everyone, very helpful! Now that I know what I'm working with it sounds like it should be ideal for my application.
That's good to hear, especially considering the price of them (free!). What identifies it as an 800 CFM?
Everything seems to move freely and it looks real clean inside the throats and from underneath; haven't stripped it down yet so no idea what lays within.
Recommendations for kits to look for and/or avoid? I'll pick up the Ruggles book before I start rebuilding it, hopefully late spring or over the summer.
No idea what it came off apart from it coming with the 350 intake. It was missing two mounting bolts and the other two weren't too tight so it's an assumption that the two were together on an engine. It will be going on a pretty much stock, low mileage rebuilt 350. Sounds like it might have a cam upgrade but I'll have to look through the rebuild receipts to see if there's any mention of that.
Great information, thanks!

Cliff sells quality rebuild kits and parts. Almost all the non CCC front inlet carbs after 1975 are 800 cfm. Cliff's book shows the bump in the primay's for 800 cfm.
