67 442 Qjet question

My 67 has a Qjet that by the numbers is from a Cadillac. At 6000' elevation its puking out 7% CO at no load cruise. I wonder if anyone would know what main jets and needles this carb came with? Carb Number 7027036. TIA

I have now found info that this carb number was fitted to the olds 330. Can anyone confirm?

Thanks trip. Thats the info I found as well. The 3 shows that it was a caddy division by number breakdown. Thats what the confusion was. I also found the power piston stuck in the up position. I have to get in there and clean it up. When its down I'm reading about 2.3% CO.
