but doesn't a carb give the car a sixties old school personality?

Yea it does and especially good for garage art... LOL Carbs still work obviously but EFI is definitely the way to go unless you are building a drag car or something that will operate at WOT most of the time. However, for day-to-day drivability EFI is the way to go.

Obviously the car is yours and so long as you are happy with the set up it doesn't matter. I went to EFI on everything I have and will use EFI should I build something new. In my case I had an original 6 pack setup on my Challenger which doesn't get driven very often and I have gone through and set up those carbs a dozen times which I got tired of. Alternately my 01 Viper and my 10 Challenger can sit for months and fire right up without issue; so I decided that my 70 challenger needed the same. It doesn't start as easily as the Viper or new Challenger but definitely better than with the carbs; more importantly it idles well, throttle response is excellent as is acceleration.  Best of all, I can change pretty much everything with a key stroke or mouse click, I can see exactly what it going on from idle to WOT at a glance; no guess work, no reading plugs, no changing needles and seats or jets, etc. It runs the same in any weather.

Not at all bagging on your carb, I ran them for many years, just giving a another view point. I am sure that car is a beast and a blast to drive.

As I've gotten older I've come to dread leaning over a hot engine playing with gasoline... forty years ago it was what we all did & never gave it a second thought... These days I think about fire & how even if I get away without getting burned my car that I have so much time & money invested in will get damaged... I've tweaked many Holley's, Carters & even a few Rochesters... None have ever worked as well as EFI, more HP, maybe, better overall drivability day in day out, hot weather, cold weather, sea level, 9,000 feet doesn't matter, twist the key it starts, it idles, it leaves from a dead stop without a bog, a stumble, a flubber....

Many years I made a living wrenching, use to build allot of carbs, I could fix allot of problems, I continued to do carbs long after allot of shops weren't doing them & wondered why other shops were passing on easy work.... Then I got a customer who had a carbonated truck but his daily driver was EFI... I built the OE Holley on his 460, he was thrilled with how much better it ran but there was a problem, only on cold mornings it would die at the third corner leaving his house.... I played with choke tension, choke pull-off high idle steps.... problem was it would go lean just as the high idle fell out....  I made it better but never perfect.. Anyone who grew up driving a carb would expect & accept it... This guy only drove EFI stuff & I couldn't make him happy... Back in the day carbs were fine, our expectations have changed.....  And while I grew up with carbs I sure appreciate a good working EFI...

so is FI-tech the economical way to go for my car?
Have they worked out the bugs on the unit that allows you to keep your
regular fuel pump??

No sure what bugs you have heard about so I cannot comment about that, but no EFI system will allow you to use your normal fuel pump unless you also use something like the Fitech "command center" (Edelbrock has a similar system) but in general these systems are not well accepted. Anyone serious about EFI also installs a EFI fuel system.

Agreed.. Command Center from the outside seems like a cool idea... The reality is a EFI tank with an internal pump & a full flow return is the best choice.... Returnless is easier & works pretty well, modern cars have gone that way but in the first tries in OE applications the injectors got bad deposit issues because there's no cooling... In a return system the fuel going back to the tank pulls heat from the injectors... They solved the deposit issues in OE applications with non-stick coatings but I'm not sure the aftermarket injectors have the same coatings so rather then take a chance I choose to run a return system...

Can you run a return system if I just have a 10 gallon plastic fuel cell in the trunk?

is this ram jet setup better than an FI-Tech setup??

You can, though personally I'd want a bigger fuel cell cause when I get in my car to go somewhere I don't want to be stopping every hour to refuel....

FiTech isn't the greatest system by a long shot, it's pretty basic, it just replaces a carburetor... There are plenty of port injection systems which are going to have the potential to be more precise... FiTech is cheap & easy, it self learns so you don't need to either learn to program or pay someone to program, it's far more advanced than a carb yet doesn't cost much.... Until FiTech came along Holley sold their similar system for over 2K, now they sell one for 1K.... But I'd rather give my money to FiTech since I've been burned by Holley in the past & when I had an issue with my FiTech system FiTech took care of it with no BS...

I have both; a Holley system and a Fitech system; as stated, the Fitech is very simple and intuitive but not as comprehensive or versatile in terms of tuning and eking out every bit of HP.
