Hello Koos,

I ran into you at this car meeting in Drachten the other week, you were looking at this wiring diagram in a Chilton manual for a Cadillac Seville remember? I made a promise that I would scan that particular diagram and mail it to you, but lost your card..........

So if you still need it, let me know.

I have a used Rochester Q-jet from a 1978 Riviera for sale,
came from a perfect running 350 engine. Let me know if you're interested.

 

Go with the 650. I had one on a 350 buick back in the day and it ran strong.

 

4bbl used by the factory was a 750cfm.

 

At LEAST a 750 CFM!!!!!!!!!!!!! Nothing smaller! Try and stay with a Quadrajet if you can. I have the Holley 750, and I believe the Quadrajet is a much better carb for mostly street driving after its set up correctly. Mark

Sorry Koos, this is what i meant:
between thous two, go for the vacuum sec, Q-jet replacement (spread bore)!

I'd strongly recomend a Quadrajet Spreadbore 750cfm or 800cfm. I also have a 69 Buick 350. The original Quadrajet was really corroded as the cr sat for the better oart of a decade in the original owners garage. When I bought the car it ran a slow off idle. I rebuilt the carb and it ran like a champ! It pulled very strong and the quadrajet is so easy to rebuild, tune and fix. I ended up stripping out the threads at the fuel intake and put in a Holley Street Avenger 670cfm for the time being. The Holley can't compare to the Rochester. Maybe I should have went up a size. Who knows. But I do believe that the Quadrajet is a better carb. Flip over a Spreadbore and look at those big coke can secondaries. Now compare that to the silver dollar secondaries of other aftermarket carbs. Any questions?
I'm currently looking for a a new Quadrajet 750 or 800 cfm to rebuild and use or fix my original.
Wait, actually, ya go with the Holley. In fact, I've got a nice new Street Avenger I'd be glad to sell you really cheap!
