[1976 Grand Prix 455]

This is the number on the Rochester on my ‘76 Grand Prix. Can someone tell me what the numbers translate to and what the CFM might be? Thanks in advance.

Rochester, Pontiac division, automatic. from 76/77. Should be ~800cfm.
I had Cliff set up a very similar one for my project - you're GTG.

Anyone know what the “ASR” stands for/means?

I hope that's not one of the goof ball 76 units with 3 primary metering rods. I think those are all 7 digit numbers, at least the one I accidentally bought was....

17056266 is a 1976 350 cui LEMANS, GRAND PRIX, F A/T FED Quadrajet with
71 main jets, 43L primary rods, DB secondary rods, and 7044068 power piston spring.
It´s an 800 cfm casting with the APT under the aluminium plug like all the "good" ones.

Dang. More information than I could have hoped for! Thanks Kenth.
