"Been looking on the affordable fuel injection" No such thing. For the cost of the EFI set up you could have a nice big block in the car. You think carbs are hard to set-up, try messing with the computer, bungs, sensors involved for EFI, not to mention the fab work...unless you buy a Mopar pre-fab kit and those are $$$$$$$.

What exactly needs to be done for fabrication? I thought that unit was already set up for bolt-on to a SB Mopar application.....

And how much do you think it would be, total cost? What would you pay for a "nice big block?"

So how does buying a new bigblock solve carburetor problems???

The Affordable kit is a GM ECU and TB. I'll speak in some generalities here:
The 'standard' kit includes teh 305/350-sized TB, which is good for about 250 HP of airflow. The stock 454 TB and injectors (which they list for the 'over 360 kit') will be limited to maybe 300-325 hp based on the throttle body and injectors they use. They reprogam the chip to match the engine specs you give them. If you mod your engine too much, it may no longer perform as well. Sure, you could then adjust fuel pressure and put some specially-sized resistors on the sensors to trick the ECU, but personally I'd rather have one I could tune via a laptop.

As mentioned, Megasquirt (MS) is a good item for those that want to tune their own, or want near-infinite flexibility if they ever modify their engine down the road. MS (and probably the others, too) allow ECU 'learning' via wideband O2 sensor (that is above/beyond mere closed-loop corrections!). Try that with your carburetor! MS will allow you to control spark if you want, too – you could do fuel first and spark later (or vise versa).

Setting up the hardware, whether it be TBI or port EFI, depends on your budget, HP target and how much you are willing to do yourself. Low HP systems have lots more options (like the TBI or the Magnum beerbarrel) while higher HP gets more expensive (as usual).

it doesn't but thinking you can just throw a EFi set-up together and start driving isn't logical. Plus all b-bodys should have big blocks.

x2 on the bigblock!

Yes, EFI will take a bit of tweaking, just like most any other bolt-on-part shakedown. Probably more tweaking, but tweaking can be far faster, and if done via laptop can be done any time you drive the car, without opening the hood.

One HUGE benefit I see to EFI, though, is that it is far faster and easier to make fueling/spark changes than with a carb. If you have the knowledge/experience to know what an engine needs, it is easier to modify the system than with a carb (if you're computer savvy, anyway). No rods, jets, air bleeds, choke adjustments, distributor curves – all are changed electronically (some of them while you drive!).

I have a wideband O2 gauge on one of my carbureted cars. I can tell where/when it is lean/rich, but even the smoothest tune is a compromise somewhere, either in MPG or HP or idle quality. It also loves more timing advance when cold, but fights against it when hot. I use an MSD Timing Computer with to handle that, but that’s a crude compromise, too. With EFI it's adjusted via intake air and coolant temp parameters.

Yes, it can be pretty straightforward to slap on a carb and get to work, but there's no learning or envelope-pushing involved there.

, and all of the problems that carbs have while fuel injection is turn key and go. Not to mention rich idles and eyes watering, etc

in reality it would be cheaper to pay a competent carb tuner to tune what you have than it will be to install and tune an EFI setup.

Agreed. But where to find this 'competent' person? Not at a local garage these days - so it's specialty shops only. And they need to be within driving distance, because they really ought to have the car to tune it on...
