800cfm Quadrajet #7042240 MB 241 ; Bought it intending to have built for my 455, but have since decided that I'm going to go the Holley route. Good rebuildable carb, all the linkages work smoothly, none of them seem bent. Only thing wrong with it as far as I can tell is the broken plastic vacuum piece, as shown in the pictures. I was told this came off of a running car. I don't think It has ever been messed with by someone who has no idea what they are doing, either. 80$ shipped via USPS, I am located in Billings MT.
Deal pending with 6769Riv. But to answer your question, they look good, they arent stripped out and there are no threads missing or overly worn.
