Title: 1990 DELCO 9C-Application Index Sheets
Post by: SUPRCHY on December 07, 2025, 06:43:49 AM

Looking for a copy of 1990 Vehicle Application Index pages from Delco carburetor #9 P&S manuals. Hopefully the snapshot of a 1989 sample was attached.

Thanks,

I'm just trying to verify the last vehicle installed Quadrajet. According to the "internet" the last  passenger car Qjet was #17088152 and it was installed on Oldsmobile 403 VIN Y engines. They were claimed to be Cadillac Brougham, Buick/Olds/Chevy Estate Wagons. I have a copy of the 9C-Bulletins from the Big Book, but it ends in 1989. Just thought maybe there was a 1990 copy floating around that would verify if the above is correct.

Thanks for any info,

SUPRCHY

  The Cadillac Brougham used the Oldsmobile 307Y engine from I believe 1985 through 1989 for sure, and possibly into 1990. The Quadrajet used was the Electonic version. I had an '89 years ago and I think the carb number was something like 17086005, not positive now.
 But for sure the 1991-92 Broughams used a 350 Chevrolet engine with fuel injection, they no longer had a carburetor.

 Hope this helps.  Rick
