Helping a young neighbor who's Dad recently passed away, clean out his garage/ shed and came across these two Carter/Quadrajets. I have no idea the CFM rating of them, hope someone can help. I've been told that Quadrajets can be a pain to rebuild and finicky to work with so I'm thinking the neighbor's Dad, who had a bunch of Corvettes, may have pulled these and replaced them with Edelbrock or Holley carbs. Can anyone ID them? Should I just trash 'em? The numbers on one are...8904 1901, 0983 W......and the second carb is 7044217, M1 ....FF. Any help is appreciated.......Thanks, Don.
