302 2bbl Carburetor
I have a a 81 F150 with a 302 2bbl. I think the carb needs rebuilt but not sure what carb it has. The tag is missing. Anyone have a carb that would work or any suggestions?

pull it off, take it to your Ford dealerships parts counter and tell them order you a rebuild kit for it. Let them do all the legwork, they charge enough that they deserve the aggravation. I would probably just get the Factory rebuilt carb if they have it available.

I would probably go to a 4 barrel, just for the pure and simple reason that it will give you some power increase. The performance gains of a 4 barrel swap are over-rated in my opinion. On a stock engine, there is only a small performance benefit. Stock engines usually come with a carb that is capable of supplying as much fuel and air as the engine combination can handle. You will get a little help from a properly matched 4bbl. and intake. Be sure not to use too big of a carb. When you use a carb that is too big, It just kills your low torque and your throttle response. Most of the guys at the parts counters think the bigger the better. I have had much better performance on stock 302 engines with a 500 than I have had with 600 or 650. I have seen several 351w engines that do better with a tricked out 500 than they do with a 600 or 650. .

If you use a quadrajet (don't flame me), it has smaller primaries than most 2bbls, so it will yield better fuel economy, however the downside is that the secondaries are so big that you can watch the fuel gauge drop when you put your foot in it.

I use this pickup to push snow in the winter and screwing around in the summer. It isn't an everyday driver. Fuel econimy isn't as big of a deal, however I would like it to start and run good and I could use more power. Should I check some junk yards for a stock 4bbl intake and carb off a 302? What do you recomend? Also, is it as easy as taking one off and putting the other on?

Yes, it is pretty much just pulling one off and putting the other one on. Nothing complicated. If it were my truck, I would buy a new carb and intake. Aluminum intke will save you weight, and right off hand I cant really think of a stock 4 bbl intake I would want. The carb is going to need to be rebuilt if it has set up for any period of time, so you would be better off just buying new one. Personally, I like weiand intakes and Edelbrock, or Carter carbs, for street use. Edelbrock and Carter are the same carb, you just dont pay quite as much for the name Carter. Holley has some great carbs and some great carb intake packages. Holley actually owns weiand and they sell their carbs and intkes as packages. I know lots of people who love Edelbrock intakes, I just have not seen the broad power curve out of their intakes I have seen with weinad, just my personal opinion. The only carb I would be sure to stay away from on a stock 302 is the Holley Double pumper, Stock 302 just cant handle that quick shot of gas when you slam it to the floor.

Can you get q-jet manifolds for Ford, or do you have to use adapters? To be quite honest with you I have never checked because I have never even remotely contemplated putting one on a Ford.

Had my 70 302 engine rebuilt with the upgrades for the swap you are considering. Find there is more power than needed and rarely get into the secondary. Like using half a 4bbl. In looking back, realize the original 2bbl setup provided all the power needed. If interested in dressing out the engine, there is no noticeable difference whether engine has a 4 or 2bbl. Would go with alum intake from list mentioned previously. Suggest the polished over the satin. Although cheaper, find satin too diff. to maintain appearance, better to put the money up front than taking satin to polished finish, speaking as someone who has done it. IMHO
Anyhow, had an urge to chime in and add my $.02. Good luck and sure you will be please with what ever you decide.

I'm having problems with my '83 2 bbl and I'm also wondering if there is a simple 2 bbl carb that I can get that is easy to tune, but isn't a performance setup. My truck isn't fast, and I'm not trying to make it fast, just reliable.

I have never used a Holley 2 bbl, so honestly I could not tell you if it requires an adapter. I know the Holley is easy to tune because I have the parts breakdown for them in my Holly book. Simply put, it is just half of a Holley 4. If you call Jegs or Summit, they can tell you if it requires an adapter. I am guessing thats probably where you would be buying the carb anyway.
