now you are talking, pm DaveM about this im sure he will be all ears. installing a carbed intake is easy, the engine block may not have a fuel pump mounting provision as they cast over the later small blocks. an ecletric pump will solve that. other than that, eat that ozone layer!
To be honest I like the carburetor myself also. I contemplated the Lt1 then the TBI setup on a 350, but just end up using what I know and like the looks of. I think if fuel economy was the issue we'd all be driving civic's lol. What carb are you going to run? I believe you may have to swap distributors. If you have the stock electric fuel pump a fuel regulator should work.
im thinking theres a good chance the fuel pump mount is ready to go (including the hole for the fuel pump pushrod) on an '87 engine but i have no idea if the cam on a fuel injected engine has the fuel pump lobe on it. easy to check though. remove the flat plate that is over the fuel pump boss and look for a hole (5/8 dia maybe). insert a fuel pump pushrod holding it in place with your finger. have someone turn the engine over slowly by hand and see if the pushrod moves in and out of the block any.
i also have a feeling that 87 was the year they changed the angle of the two center bolts on either side of the intake (bolts closest to the carb). earlier intakes need some adjustment to fit correctly (meaning oblonging the holes and using some angled spacers) or finding a factory quadrajet intake off something like an 87 monte ss (which would give you the mount for an egr) or the correct aftermarket intake for that year of block.
i guess you could use the intake fuel injection fuel pump with a regulator but id be more inclined to use a mechanical pump.
you might want to think about what this is going to do regarding emissions legality before you do it tho.
you are right on the intake part "not as drunk", and if i remember correctly we used a manual pump on a swap over we did on a 55 chevy for my daughter...
If your heart is set to run a carb do you think investing more money into a 305 plus the time and effort is worth it. Or keep running the 305 as is and find an older block that don't require all the bells and whistles build what you want and drop it in. just a thought.
Always the critical responses to posts, if you have nothing positive to add, why spout off?
Since you have no sense of humour, I will explain.
IMO changing a fuel injected engine to a carburetor seems a bit backwards ( maybe not in North Bay). I was being a smart a$$ by making the statement of going to wooden wheels from todays current aluminum wheels and figured adding an "LOL" at the end of that statement would make most people ( maybe not in North Bay) know that I was making a joke.
I was going to make a useless post about some POS car having a bit of chrome under the hood, but some numbnut beat me to it. Stay on you side of the sandbox and all will be well. Just sayin'
You'll need a new distributor like a large cap HEI, and rewire for it. TV cable corrector for the throttle linkage. Some way to hook up the torque converter lock-up. As well as the intake and fuel pump issues mentioned above.
Can I ask why you want to do this? What is the goal?

to end the enslavement of the human race by computers, thats what im thinking. when murica launches that missile that disrupts all computers from working, diesels and carbureted engines will still be purring along
Why do I want to swap from tbi to carb Well the 305 is in my 48 chev p/u it is a 4 spd std IM a old guy do not like computers and like the old school look of carbs TBI to me is a pain old school carbs easy to work with. But I may find a old 350/305 carb motor and drop in . Has anyone did the tbi to carb swap ?If so how did it work out? One more thing WOODEN SPOKED WHEELS are on order they will look good on my truck LOL
Thanks for all the good info guys NOT sure what way I will go. One more thing can you remove all the ser# on the block all emissions stuff and get a way with it? Just asking
Technically you could get away with it as long as no one looked under the hood. given the choice Id opt for the missing emission component charge cause they will charge you with that anyway plus a few nasty federal offenses

TBI to carb swap Anyone done it? how did it work out?
I've done it. installed an 87 factory quadrajet carb and manifold. also installed an early hei dist. due to my engine having a factory roller cam I had to install a melonized dist gear. factory roller cam did not have fuel pump lobe so I installed a carter electric pump.also removed all the serpentine stuff and installed a regular rotation water pump and early type alt mount. thing runs fine.
you can install earlier heads on that block to get rid of the center bolt valve covers and this the installation of the early heads (86 and earlier) also allows the use of a regular intake where all the intake bolts are the same angle. this also makes the engine appear older. I have been told the moe looks for center bolt valve covers as a clue to the engine being from the emissions era.

actually in a way this worked for me when the MOE pulled me over last year, my engine in the tow truck is so filthy do you think that MOE guy wanted to get his hands dirty? i think not. he couldnt identify my engine and i played rather daft. i suppose he could have dug for the block codes but it was also 9 at night.
