Hello from a brand new newbie, my name is Fred. A friend sent me this link to hopefully ID a carb I just re-found cleaning my Mothers' attic last week. In the mid '80's, I thought I needed a carb for my GTO. A friend at a parts store told me he could get the right one for the car. I bought it, and then forgot about it as the driveability problem was traced to the distributor. Fast forward to now and I have a red and white GM box with a new, never installed Rochester quadrajet I know nothing about. The part number on the box is 17054819 and underneath that is 22-6057. On the left side of the carb stamped vertically is the number 17054910. There is a small yellow sticker on the left rear that says service. On the right rear mounting flange is the number 2847, looks like it was put on with a magic marker? If anyone on this site can shed any light on this carb, I will appreciate their wisdom in advance. Thank you very much.

 Actually, the number stamped vertically on the left side is probably the correct part #. 17054910 was a Service Replacement for the '73-'74 Olds 455cid SD A/T. The correct part numbers it was to replace were, 7043270 (1973) and 7044270 (1974). I also believe this is the 800CFM version as well. It came with .075 Primary Jets, 49B Primary Metering Rods, K Secondary Hanger and BV Secondary Metering Rods.

 Excuse me. The application for that carb was for a '73-'74 Pontiac 455cid SD A/T. Sorry. :)
