Title: Quadrajet information needed
Post by: grin68 on July 04, 2017, 07:47:08 PM
I have several QJ carbs that I need help in identifying if someone could help me out...

The first one is Rochester Quadrajet 7045222 R6 0515 so from the internet I think I have it identified as '70-'75 Chevy 4bbl Auto built on the 51st day of 1975 is this correct? It was stamped vertically.

The second one is Rochester Quadrajet 7041208 DN so from the internet I think I have it identified as  '70-75 Chevy 4bbl Auto built in 1971 but dont know what the DN stands for.

Are these worth anything?
Any and all help will be appreciated. Dan

Opps forgot a set of numbers on the second carb 7041208 DN 2520... (the DN would be the plant not to worried about that) this one would've been built on the 252nd day of 1970?

 7045222- 1975 Chevrolet Corvette 350cid, Federal, High Performance, Auto. Trans. Yes, you have the dates correct. .072" Primary Metering Jets, 46K Primary Metering Rods, "K" Secondary Hanger and CH Secondary Metering Rods.

 7041208- 1971 Chevrolet C/K 20/30 350cid, Auto. Trans. .074" Primary Metering Jets, 39B Primary Metering Rods, "K" Secondary Hanger and BA Secondary Metering Rods.

 These are the stock metering internals. As for the "DN", yes, that was a plant code given to a specific car from the factory. It was ONLY used on that car.
