I have 2 k5s with 2 305's and 2 q-jets. I bought the '85 6 years ago and have always been fighting with the carb. I bought my '84 in january and the everything is fine with it execept the front drivers side (alot of damage fender,hood and grille/radiator mount are screwed for good) makeing it illegal to drive so I figure I will switch the 84's carb to the 85 to get it running better for daily driving and take the 85's carb inside clean it up adjust it then put it on the '84 and make the final adjustments. I noticed they weren't quite the same when I opened both hoods but proceeded to take them off. When I tried to put the '84's on the '85's i ran into a problem and they are way different and wont interchange. Question is, 'What should I do?' I know all I have to do is adjust the 85's and put it on but i dont want to mess with it much longer and am getting sick of it. i am thinking of putting the '84's back on the '84 and just getting a new carb for the '85. My dad has told me forever and, I am seeing myself that the carbs from this time period were really good or really bad. Looks like i got a really good one and a really bad one. Anyway I am wondering what you would do. Would you rebuild the '85's q-jet get a edelbrock, holley or something else. I have an old carter (mopar) that I could make work for the 305 but I wouldn't want to put an old 440/6 carter carb on there. My budget is so tight it is cutting circulation off to parts of my body. Rebuild would be cheaper but new would be easier. I'll get some pictures of the carbs. It would probably make things alot easier for you guys to help me if I did so, I will. What would you do?
