Cliff,
I recently bought a car with a 1977 350 Pontiac engine that has a 17057262 0177 ARK Quadrajet on it. I purchased your performance rebuild kit for it, it only took a couple of days to get here. I recently rebuilt a 1968 carb with your kit that runs fantastically.
Researching this carb, I found posts or messages by you indicating this was a good performance carb you may have run on your 455? The secondaries have a chopped 0, or D format. I thought that was an indicator of a poor performance carb, and believed an earlier style round secondary type carb would be better? Am I confusing this carb with another performance Rochester with the same number? Could this be an 800 CFM carb? And if it is a good carb, why would they put it on a very low performance, 7.6 to 1, 150hp 350 engine?

The 17057262 is far superior to the 1969 Pontiac carb in every respect.
It converts easily to E-choke is one of them, and has APT.
I don't know what you mean about "D" shaped secondaries, those were the intakes from 76-79, not the carbs....Cliff

Oh. That's great! I didn't realize one of those black gaskets stuck to the carb and was D shaped. Ha. How far off are they jetted for a 455 with a 236/252@50 cam?

They will need more idle fuel and slight recalibration (jets/metering rods/pp spring) on the primary side. Secondaries are WAY lean as they used DB rods in them.
Easy things to correct during rebuilding and they don't need a lot of help anyplace else.
I recommend having us put together a custom rebuild kit with tuning parts. We'll include an HP accl pump, high flow N/S assembly, idle tubes, jets, metering rods, PP spring, quick release choke pull-off and E-choke conversion (recommended).
Pretty much plug-n-play at that point, that's all that's ever been done to mine and it's been flawless now for decades.......Cliff
