Just wanted to give my opinion on the system so far. I have had it completed for a month now and am very happy. Spent considerable time and and money on the fuel lines and proper routing but other than that, the kit itself was fairly straight forward.

This is on top of an 11:1, aluminum headed 440, making around 550hp. Right away noticed great cold start and better throttle response. It still seems to be sorting out the transition between idle and cruise, but its bairly noticable. Goes lean for split second before it corrects itself, I think it still in the learning process and the weather has not allowed for a lot of driving.

I did have one problem. I, or thought I, upgraded the pump to a Mallory 5110FI. Suddenly after about 100 miles the pump had a major failure and broke internally. We had pre-filters and post filters in the system but it seems something got in there and caused an issue. Anyway, updgraded to all Aeromotive filters and had Mallory re-issue me a pump. So far so good. With this set-up at this HP it keeps up well. Only uses 70% duty cycle at 45lbs. Again still have some fine tuning. Love the product.

Looks great. Out of curiousity what cam are you running? Also are those straight or angled plug heads? If angled, what headers did you use?

I've been thinking of switching over to an easy efi from a gen VII I have been running for years. It's still a bit finiky and considering I built the car for my father I don't like to have to take time to mess with it if necessary. Thanks for your input.


When I die I want to go like my Grandfather did, quietly in his sleep. Not screaming like the passengers in his car.

Glad to hear another EZ EFI happy camper!

They system might just have to learn, but they have a setting ( i forget what they call it ) but it's what the acc pump would do for a carb, that can be tweaked to give more or less fuel at the transition.

Good luck and keep us posted!

Have you run the car at the track ... with this system and a carb? ... perf diff ? .. and MPG data ? ... cost so far?

10 - 16 AFR IIRC

I've leaned it out to 15:1 on a long highway cruise ( 3200 @ 70 mph) and got the 16 mpg's

it liked 12.2:1 at WOT on the dyno while I was testing for most power.

Whats nice is I was able to open the headers and the EFI compensated for the change - keeping it at 12.2:1

so you can't go higher than 16 to 1? ..... I have heard some tests on econo-boxes going as high as 25/1 using water-injection with it.

I dont think so - i'll have to look -

My plugs were lean, mean, and clean at 15:1 when I pulled them... i would not go any leaner on my motor...

LOOKS Great! I am glad to see you are happy with it, I will be buying that setup for my 408 once I get closer to actually being able to start it in the car.

What are you using for heater hoses, that is just what I have been looking for to use with my setup?

Thanks. I run the Lunato Voodoo 60304 hydraulic cam. Straight plug Stealth 84cc heads with a little massaging done. I think you will be happy with the upgrade. Word on the street is this will be the similar set-up that the NASCAR boys are switching over too. So expect a lot use of these EFI products.

Thanks for the heads up. I actually did adjust the Accel pump setting up a few clicks, but it made the transition a bit worse. Like I said, bairly noticable unless you were staring at the display.

Have not had it to the track yet with the EFI. Carb it ran 12.40 @ 111 with 3.23 gears. I am suspecting I may get some more MPH out of it with the ability to fine tune WOT at a touch of a button.

I have currently been able to gain 3mpg with the 4 tanks that we have run through it. A mix of City and hwy driving.

The cost is not cheap as there is quite a bit of cost(variable) in the fuel system itself. I am into it somewhere between $2500-$3000. But I used all AN black fittings and hose with a combo of formed SS hard line.

I have tried leaning it out a bit. I am currently at 14.1 idle AFR, 14.9 cruise and 12.9 WOT. I know those do not seem that crazy lean but these are dramatically leaner numbers than I was able to get with the carb. If I go much leaner at idle or cruise the car begins to surge I think we have found the sweet spot. I think these are pretty good numbers for an 11:1 big block.

Man, that really looks good. I have been wanting a set up like this for my ride. I dont think the $3000 is out of the norm. Although I would be curious to find out how much the Edelbrock xfi costs.

Yes, the hood clearance takes some thought. You can't use a normal drop base air cleaner as it hits the fuel rails. So we ordered a Spectre aluminum plenum box and it only takes up 2" of space. Has (2) 4" inlets on each side with 4" tubes. I currently can't get the tubes to fit so we are just going to run the plentum box with fine pre-filter foam covering the openings. I will post pics on that soon and it should work fine.

Someday when I get some time the solution maybe using oval tubing to get the hood clearance.

This is in a '68 Charger with an RPM intake, so results may very with different combos......bottom line is can't use drop bases with the EZ-EFI.

Thanks for the kind words. All the black hose is the Russel Pro-classic with combination of Summit, Trick Flow and Russel black fittings. Size -12 should be equal to the 5/8 heater hose.

Well you will have look at other solutions most likely with a stock hood and this EFI set-up. There are some options out there if you are serious. Like I said, check Spectre's website.
