Building a driver - use carburator or fuel injection ??

Building a driver - use carburator or fuel injection ?? - 12/13/11 09:35 PM
I am in process of building a 1970 B Body that I will drive - all over the place I hope ! . . . 360 with about 9.5:1 pistons, 1970 340 type cam, 727 auto and 3.23:1 rear end gears. Question I ask myself, is : should I go the route of fuel injection ?? You can get great products now, that you don't even need a return line ! They learn and then you just get in and turn the key. Granted it is about a $2k touch !!! That could pay for a lot of fuel with a carburator !
However, putting 10-15k miles on the car in a year, the ease of operation with the fuel injection would be appreciated - idle, start when cold, cold drivablity, etc. . . .
What would you guys do ?? I am good with a TQ for the 360, but wonder about upgrading to the EFI . . . .
Thanks
Mark

I'd go efi, especially if it's a 4 season car...I wish I would've put EFI on my DD before kids when I could've afforded it....my car is a bit of a PITA in the winter with the electric choke being somewhat finicky and winter blend gas...
I'd probably start with a magnum 360 and use the '96-up JTEC computer with a tuner.

For as mild of a 360 as you want, you should swap in a 90's magnum 360 and run it off of the stock ECU. You can still rebuild the engine and have the cam reground to be a little more aggressive like the stock 340 cam. Swapping in the stock electronics won't cost you much and ideally suited to an application like this.

I would go the TQ route .....with a 904 trans.
FI still is a PITA, expensive and does not work right all the time.

What happened to the company that had EFI units that resembled carbs on the outside.
Financial ruin?

Not if he would use the factory ECM and a Magnum engine.That setup is bullet-proof as far as dependability is concerned. He could even use the A-518 O/D transmission for even better economy and drive-ability.

That's what I'd do for a driver. Not the max hp setup, not the hardest/most expensive setup and pretty hard to kill.

Injection is so much nicer than a carb, I wish I had injection on my streeters. Sure would be nice when driving in different alititudes and not have to change jets.

I've been batting around the idea of running an early 90s TBI set-up with a Megasquirt system on my 318 Coronet. Depending on what the JY parts cost I could probably have a working system for under $600.

You can use a 92 Dakota wiring harness to wire the fuel unit on a Magnum 5.9 3 wires to connect. There's a thread in the tech archive I think. A member here named Scott [NFury8] has done this swap with a 2 pin 518 in a 69 W series CrewCab. Autometer sells a speed sensor that allows using the mechanical speedo. I'd use a Magnum engine either way

If you have the money,and you are not good with tuning carbs,then yes go EFI.
Me personally,I like to work on my cars for fun,and carb tuning is one of my favorite things to do. It cool to see the diff from changing one little thing. You pretty much only have to mess with a carb(once tuned right initially) if you are changing elevation and/or weather change,and at that it is usually just a jet change.If you get a wideband a/f gauge it makes fine tuning a carb very simple.

Re: Building a driver - use carburator or fuel injection ?? - 12/14/11 06:48 AM
IF I want to run a carb I use a ThermpQuad, easy to tweak and they just work when right, especially if you go with the 9800 aftermarket ones with the electric choke setup. The one on my Dart has sat for 4 years and I started it finally after a few years of setting. The accelerator pump was stuck but with some WD 40 and a few pumps of the rod it was AOK again and started running great, even on that old gas in the tank, even did a quick burnout in the driveway after everything was up to temp and working smooth again.
If I wanted max drivabilty and MPG I'd definitely go EFI, but like said many after market setups are way too spendy and you have to modify stuff to make it work. Some of the stock stuff and the later 360 factory stuff can can probably be done cheap and mega squirt and others might be a option if you want to go low bucks and aren't afraid to make things and do it yourself.
Simple, go TQ, more complex but maybe worth it EFI.

I agree. Then I'd hunt for used bolt on hipo parts from the Dakota guys. Cam, R/T heads, E-brock heads, etc.

Re: Building a driver - use carburator or fuel injection ?? - 12/14/11 04:28 PM
I am all good with my TQ's. I have had one on my 74 Duster360 since I got the car way back when. Have rebuilt it a couple of times (over 100k miles since restoring the car in 84 !!)and it runs great ! I also changed the Lean Burn on my 77 New Yorker 440 to standard electronic ignition, and about a 75 non-lean burn TQ. That car RAN SOOOOO good ! You set the choke with one pump, turn the key, and GO. It had NO hesitation when cold, and after about 2minutes was off the choke and running great ! . . . I always figure if you follow the factory steps for rebuilding a TQ, then it works great ! Course the above cars are all stock, so that makes it easy.
I already have the rebuilt 360, so, I am going with that - I know a 90's magnum 360 with the factory TBI would be cool, but have this engine now, so am going with it.
The car is not going to be a 4season machine. However, I do love to drive long distances to carshows, and the early/late year shows run into cold weather leaving from up north here. I am ok with carb, or EFI - specially the new style that do all the hard work for you ! Specially something like the Professional Products unit that has it all in the "carb" style body, and not needing a return line.
Guess it will all depend on whether or not I have been a good employee and see some bonus $$$ this year ! If so, I think I will pull the pin on the EFI. If not, then rebuild one of the many TQ's I have.
Thanks for the input . . . always a great discussion.
Cheers
Mark

Carbs aren't magic at all... Carbs are a semi controlled fuel leak... Carbs are great as long as the person driving the vehicle understands it's a carb & not fuel injection.... Back in the eighties & early nineties I'd get people in the shop with a carb complaining, they drive a fuel injected vehicle 75% or the time but this old truck needs to work... "Well on a cool morning leaving the ranch, at the second stoplight making a left the ol' truck wants to die... She'll start right up & she's fine after that but..." Yeah, Right... So if I add a bit of tension to the choke to help it through that lean area it will be to fat & I'll hear about that too....
Or the "I took the car up to Tahoe this weekend & it didn't run very well... " No [Edited by Moparts - Family Friendly Site - Keep it clean]? We live at sea level & you took a carbed vehicle up to 7000 ft & it didn't run the same.. What a revelation...
So Yeah if you understand a carbs limits & your OK with that than no problem & I realize the OP would, but my point being EFI when it's right does take care of allot of things a carb can't deal with....

Re: Building a driver - use carburator or fuel injection ?? - 12/14/11 07:06 PM
if it's not a year round, get you to work every day driver, then I'd just rebuild a T-quad and put it on....
if I were going for an aftermarket EFI, I'd probably look at the FAST EZ-EFI. only thing about it and the PP copy of it are that they are fuel only, and a lot of the drivability improvements OEM EFI systems have are due to the computer being able to manipulate the timing curve in ways you just can't do mechanically.

having driven tons of both daily, and modified tons of both fuel systems, i have my preferences.
my duster is currently a well tuned carb setup. only carb left in the fleet.
its going MPFI, with computer controlled timing and a GM ECM. looking forward to doing injection again.
reason im going efi is for better throttle response, mre fine tunability, and all the benifits previosly talked about in the thread.

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.

Re: Building a driver - use carburator or fuel injection ?? - 12/15/11 10:38 AM
If the driving will mostly be near the same altitude, a carb with electric choke will work good and is inexpensive. If you plan to drive cross country at various altitudes, the FI will self adjust for the different altitudes.
Return line should not be an issue, it helps keep the fuel pump and lines cool.
The Professional Products ProJection III is pretty affordable TBI unit (about $1,500), and MSD is going to release their Atomic EFI in a months or two for around $2,000.
The Edelbrock Pro-Flow XT is a neat TPI type system, but costs around $4,000 (although it comes with a new manifold, and distrubitor.)

Many reasons not to use standard choke.
#1 - it does not fit all intake/carb combinations, and negates the use of a spacer (unless you modify the choke rod.)
#2 - OEM choke will respond slow (if at all) unless using mainfolds with heat valve, along with heads and manifold with heat crossover. For performance the heat crossover is usually blocked, headers used, and I think the air-gap type intakes don't even have a crossover?
Overall, I'd go FI if it is in the budget.
Also, sorry about posting about the Edelbrock XT, that is a big block system.

Would FI eliminate the "steaky" fuel smell? I can't get my daughter or wife to go for a ride in the old clunker because they complain their clothes smell like gas afterwards.
I'm a cheap SOB, but it might be worth the extra $$$ if I could eliminate the smell of gas for 2-3hrs in the garage after getting home.

Re: Building a driver - use carburator or fuel injection ?? - 12/15/11 11:56 PM
I would go FI... tolerent to different blends of gas, altitude and temperature. Thats the biggie. Another mile per gallon or so is a nice bonus.
I think the stock style 90's FI is now tunable. You can probably find somebody to help with a custom tune on a Magnum based engine if you step up the power a bit. FAST EZ EFI would be a good choice also.
On the fuel smell, if its coming from gas boiling or evaporating out of the carb, FI would stop it. If its caused by venting, maybe not. Vapors from the vent don't usually make a big stink so likley FI would fix it.

Mine is definitely a boiling problem. Car wouldn't even start after sitting. Added an insulator carb spacer and it cured that problem.
It's an Edlebrock carb, car starts and runs great.
But the STINK is aweful!

If you vent the fuel tank with a return style system you'll have fuel vapors..... If you do a closed system venting into a carcoal canister with a controlled purge there won't be a vapor issue.. Thats how I'm setting up my wagon
BTW Sorry Doc my Thermoquad percolated fuel same as my other Carters & Holleys.... Drive a car for a couple hours to get it good & hot then park it in a closed garage.. You'll be smelling fuel... Especially with the garbage fuel these days..Not so with a late model car...

As you know I have been to Tahoe and even higher altitudes. My car feels like it's missing 100 HP in Tahoe from when I'm at home at 800 ft. Even though I jet it way down and even give it more timing. It's a PITA changing jets and needlies every time we go to Tahoe or Reno to visit family.
And like what was said about exhaust smell, it's pretty bad in a challenger with stock style exhaust through the valance and the wind blowing the wrong way at a light or something. That's why I run AC almost all the time so the wife don't complain about the exhaust smell because the windows are up. FI would be great for that.
I used to run straight 110 leaded race gas and everyone noticed the smell and it was not too bad smelling. Then I started really driving my cars and couldn't afford race gas. Premium gas smells pretty bad by it's self. So last summer I dumped some grape scent into my gas tank and it smelled like grape for while. lol
I have return fuel lines on both my challengers and they don't smell like raw gas when I park them inside a garage after driving them. Now I do run stock style air cleaners that keep down the sound, smell and evaporation rate of the fuel bowl I believe. I vent both gas tanks back to the valve covers.
Come spring my exhaust will smell like cherry and vannila.

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.

So my choices are $2k for FI or

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 !

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

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.

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...

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.

I love my efi conversion, I have put about 4000 miles on my car since march when I completed it and I dont know if I put that many on it in the 5 years prior I owned it. Not that it ran bad with a carb, it just always runs the same now. Bought a dakota with a 5.2 mag, used the pcm and wiring and in 3 months of weekends it was up. For performance I would still use the carb, but I dont think I would build another driver without efi.

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.

I am a hot rodder. Holley's weren't the end all. Someone had to experiment with them. Guess they never came with an altitude compensator. They weren't that advanced.
Someone had to devise a blow out check ball, gaskets that didn't shrink every time you pulled the bowls off to change jets. Advanced tech?
They quit using Holleys on Mopars, when? I ponder the reasons why?
