MANY reasons 451 ? .. but you only really mention TWO ...  
.... and I have a feeling that the OP will have an app that does not apply to what you are suggesting.
Was in a hurry, but main point is the choke may not warm up as fast without the exhaust heat valve. Also, depending on the combination of ways the crossover could be blocker or removed, the choke may not see much heat. Then there are the issues of physically connecting a choke bolted to a manifold to a carb, not to mention, it would need to be a carb that will accept a stock type choke.
Anyhow, if buying an aftermarket carb for a daily driver, a unit with an electric choke is an easy choice. If you want the best driveability then the fuel injection.

Does the scent additive really work? So my choices are $2k for FI or $10 every fill-up? ($2k/10 = 200 tanks) Might have to give it a try

Get a TQ with the altitude compensator and mod it!

a12rag, why is the idea of adding a return fuel line such a big deal to you? I mean if it is, I don't think plumbing in fuel injectors and wiring the whole thing together is something you want to do. Adding a return fuel line is the least of my concerns with going to efi.
Sounds to me like you'd be happier with a themoquad. I ran one for many years and daily drove the car and it performed well. The trick is to start with a pre-smogger thermoquad instead of one with all the emissions jetting and ports. 
No big deal to add return fuel line, however, was just saying that with modern technology, and no need for it, then why not ??? The car is a California Emmissions with vent line running back to the tank. So return line is no real issue.
I love my TQ and don't have any issues using one, but just thinking forward (like upgrading am radio to hidden stereo, or drum brakes to disc, etc). . . Calgary is 3,500ft up and heading down from here I do know the altitude does affect the carb cars - usually never been enough to make me want to have EFI . . . but if there is something better, then why not move forward with the times ??? I know it is much more expensive to start with, but over the long run, it is something that will pay for itself (certainly with lots of miles put on) . . .
Just thought I would see what everyone else's thoughts were on this kinda thing . . . appreciate everyone's input !
Cheers,
Mark

If I had the money I would be running EFI... I worked in the carb lab at Chrysler and seen carbs over the years(and I use them) plus I did alot of the early injection stuff.. for a stock engine I would just hang a production unit on it (like was said)... to me EFI is the BEST way

Now we're talking! Need some more info on the scented fuel additive, PLEASE!
Sorry, didn't see your post until now.
It "works" makes your car smell like grape or whatever. The brand above in my first picture is OK but this brand seemed to be better. The first stuff I showed came from Summit Racing, this stuff came from a candle making company and seemed to be better/stronger. One bottle would be good for 2 tanks of gas a long as you filled up a second time when your at about 1/2 tank.
Love Fla...

Something to consider as far as why to use a stock system vs aftermarket... OE software is designed to be trouble free but if something does go wrong there is self check diagnostics built in & the ability to store fault codes... None of the aftermarket systems I'm aware of have this.. Why Not???? I installed a Holley Projection kit 15 years ago because it at the time was getting great reviews in the magazines.. I'd been making a living repairing EFI & other high tech electronic stuff for Ford since 84 so it's not like I was over my head.. Well from initial startup there were two bad components, I got that fixed drove the car, got the tuning worked out & had an intermittent issue, but since the only time you could see it was with the laptop hooked up & the car acting up & those two things never seemed to occur at the same time it took awhile to fix the car.... What it came down to is the idea of fuel injection is great, Holley's execution was terrible, they sourced the cheapest components they could find with no regard for the reliability of the system... And with no built in diagnostics it compounds the problem... Looking back in a way Holley was smart, they poisoned lots of hotrodders to the idea of fuel injection assuring the sale of carburetors for many years to come.... I know there are lots of well made aftermarket EFI controllers, they have improved dramatically but if your combo is mild enough to use an OE PCM that's the route I'd take...

My daughter daily drives a truck with a carburetor. People act like carbs are voodoo magic nowadays...funny how things change because that's how FI used to be viewed.
Yes, it's like suddenly something that has worked great literally forever suddenly sucks because something different comes out, when this is hardly the case in reality.
I say flip a coin and use whatever. Both can work great in good hands, but both can totally suck on the same token for the same reasons.

Would love to try my 340 with FI going up Pikes Peak. I have had my 1405 equiped 340 up it twice now. It's a challenge for a carbed car to do it I think? I don't think my car would make it, if it was tuned for at home which is about 800 feet. At the top I don't think my 340 would do a burnout in the gravel? It sounds like a motor boat and when you give it more gas it don't do much. At the top when I go to start it, the motor spins almost twice as fast. The first time I thought someone stole my spark plugs it was spinning so fast,then it fires.  The air is really thin at the top. Todays cars with FI I think adjusts on the way up and people take it for granted that the vehicle will make it. I've proved that I can adjust for different conditions now with a carb, give me FI. 32 degrees this day.  90-95 degrees this day, the top of Pike's Peak 14000+ feet.

When I was doing the early proto type injection I
made a run up there(Pipes Peak), I didnt have the right
prom in the computer and had to stop and change over
to a different calibration... it was running so DOG
FAT... I was afraid of fouling the plugs and I didnt
have any spares in the car I was driving... after
a quick prom change it was no problem... like I said
that was the EARLY injection days for Chrysler

I believe it, it's a steep hill that keeps on going.  Kinda sucks that more of it is being paved all the time. I'm sure it's best so they can maintain a road for us to drive on. When you are on the gravel I found myself wanting to keep my RPMs up and momentum going around the bends and you sure could feel the suregrip working the whole time. I would be worried with a open rear end on a wet icy day like we did have in 2009.
