I went carb just because I like the look. If you want to use EFI, there is a vendor here that sells an EFI manifold that has the carb look.

I'm going with the EFI.I plan on doing alot of driving and I forsee some mountains in my future.I want better gas milage and the EFI gets better all around performance on the road.Roger

 

here we go again!

i am no expert, but i can answer why i went with carb. the EFI stuff was just too expensive, especially the high pressure fuel lines.

 

If you do a search you will find that this question comes up a lot. I planned on EFI, but as I get closer to completion I think I am going to sell all my EFI stuff and go carb. I am just more comfortable with carbs since that's what I grew up with.

 

Definitely do a search. Some of the threads on this are worth reading just for the entertainment value.

I went with EFI, I like the idea that I can touch the start button and varroomm! All modern cars have it for some reason.

 

dawg one thing is because of manditory emission laws even in bikes..ALL 2007 Harley-Davidsons are injected.

With these cars.I think it is a matter of taste.carb or FI,stick or auto,big block or small block.

Alot of us older guys prefer simplicity. When you have a good thing going,,,,,someone comes along and complicates the hell out of it LOL.

 

I am supercharging and it is easier with FI to tune.

 

EFI starts everytime, and handles temperature, altitude and humidity changes automatically. Carbs don't like such changes, and they get considerably less fuel economy. It also doesn't mind sitting in the garage unstarted for weeks at a time. Can't say that for a Carb. The only time you get more HP from CARB is possibly at full throttle, and the difference isn't much.

 

Carb. Easy wiring and very clean engine bay. Plus has more period correct look. I would only consider EFI if I had the Mass Flo setup. I had my wiring done in 2 weeks and that was from scratch. It's your car and your decision.

 

I went with carb because

-it's easier to install
-it looks cooler/more authentic
-EFI is more expensive and I'm a cheap SOB

 

Carb...

1. no computer and having to recalibrate it (depending on your planned set up)
2. no having 2 bungs welded into your side pipes for O2 sensors and then having to buy two O2 sensors (why are those things so expensive anyway?)
3. much easier to wire the car and a lot less wire
4. looks more correct for a Cobra

EFI is probably the way to go if you have the knowledge, tools, and experience setting up and toubleshooting an EFI engine.

i didn't, so going with a carb was very easy to set up. And then wiring the car (which was the most intimidating part of the build for me) was much easier as a result.

either way, building one of these cars is a blast!

Good Luck!

 

... can someone pass the popcorn...

ok, I went carb. I too spawned a multipage question like that as well 2 years ago.

I have a Holley 670 Street Avenger over a Hurricane Instake stradling a pair of Edelbrock Performer RPM's w/2.02 exhaust, 1.60 intake valves. This thing is running rich right now but out of the box, I got it running without much more than a screw driver. I am having it dyno tuned next month so it should light up the tires but right now, it's a blast to drive. I probably could figure out what jet to install and tailor the power jets but I would not have the benefits of a load dyon to see the effects accurately. So I'm letting the pro's handle this.


With EFI, I simply didn't want to deal with more wiring, O2 sensors, computers, more wires, and even with a Mass Flo system or Stacked injection to avoid the "5.0" look, it's just a lot of wiring.

For many, that's not an issue. Maybe I"m just old school (used to have a Carter 600CFM on a Mustang) and not too afraid to tweak a carb.

Either way, I think you'll enjoy the car.

 

I went EFI.

Start n' Go

No problems and plenty of HP

What ever you choose will be your decision and it will be just fine,

Cheers

 

First build I was scared of the donor wiring, never did a complete car. The kit came with the beautifully simple AAW harness for carb. If I ever want to inject it. The only part I do not have left over from my mustang days is an efi 351 lower. All that is needed (in my case) would be a return line a stand alone harness from mass flow or Wayne and 12volts of power with a relay If I do inject it www.verycoolparts.com, or mass flow inc . top right of your screen big ad , can't remember the wesite address. With efi once it's tuned your done. I havent had a carbed car in over 20 years and that was a big block with 2 carbs it was good on gas until you opened the secondaries . My engine builder is a carb guy I went with his advice . I have had several highly modified efi Mustangs , none with chip tuning ,and they ran great. If the carb setup turns out not to my liking, EFI here I come. Mass flow is nice , especiallyfor the vintage look, the price is right and all who have it like it , the same goes for Waynes stack EFI,Weber carb look and it's got more bling . The only disadvantage I see to a carb is mileage, the only disadvantages to EFI (if you don't go donor) is cost.Visit the sites look at the goodies , make your decision. Enjoy the shopping. Bob

 

Carb.

All the reasons stated above.

Love the MassFlo EFI, but at 3k, I can build my whole engine.

 

EFI for all the reasons above.
Start an go no tweaking I like reliability !

 

I stayed with the STOCK EFI system on both my FFRs, straight from the donor, very very reliable, starts everytime and best of all, for me they were free !
came with the donors,

Mine gets 17 MPG on the Highway and has 435RWHP stock.

Here we go again. I can easily fire either one after sitting for two months at a time. The only difference is the looks. An EFI guy never raises his hood at a show while a carb guy has it open all day long

Carb gets the nod for electrical simplicity.

Never say Never

I always raise my hood to show off the Monster, I get a kick of guys trying to figure out where the engine came from, I have heard guys say, look at that "Lightning" Engine.

Here is my car at a Show and I took OFF the hood (laying under the car in that picture) just to be able to show off the engine in all its amazing size. Always get a lot of compliments.

 

Snake bit, welcome to the family (and madness.)

EFI for me. Simple. Clean. Modern. Computer controlled. Starts on the first try.

Engine is a 2003 Mach1 281CID DOHC 305hp.

Nothing against EFI, went carb for the old school looks.

 

Sergio's SuperCobra is the best example for EFI in my opinion. I've driven that FFR and stepped out with a smile.

My EFI 302 did not provide the same results. I could run through the corners with the carb cars then the carb cars left me parked on the straights. Gordon Levy was correct when he suggested a Holley DP.

These are toys, not daily transportation. So not worrying about daily transportations issues ie: emissions (SB100) or cold start problems (I live in San Diego) or gas milage (it's a toy), I went with the most HP/$, most authentic, simplest system, a carb.

 

Hmm, low pressure drips or high pressure drips.

Some of it depends on your background. If you have messed with computer controls and feedback systems, EFI might be easier to deal with.

EFI parts are not cheap so it helps if you have the EFI from a donor or can find an inexpensive source. If not, a carb is a less expensive choice.

The EFI is easier to supercharge, which is a decent way to bump the power on a stocker. This can allow less up front expense and will let you learn the car. Strap on more power when your funds or experience allows.
