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.

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.

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

Cool .... have you tried REALLY leaning-it-out ? ....what is the range of the AF #'s ?
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.

it looks great.did you have any clearance issues with the hood?what kind air cleaner are you using?
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.

i have 68 charger also, and i am using drop base air cleaner right now with my indy dual plane.
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.

Installed
Very nice custom plenum. I have the same Spectre plenum on the car now and made it work.
I do not see any heater hoses?

Check your timing, specifically the mechanical advance. The EZ-EFI does not control timing and with some of the light advance springs installed in performance engines, the weights are on the verge of opening at idle. The EZ computer sets the idle speed in neutral but the advance weights have advanced the timing a bit so the idle speed is up. As soon as you drop it in gear the motor lugs down a bit, the weights drop in and timing retards and the idle drops to a point where it stalls. This happens with carbs as well but with the EZ-EFI it is very touchy. Get the distributor recurved so that there is no advance before around 200-300 RPM above your idle speed in neutral.
Using one of the lightweight springs and the lightest of the stock springs has worked well for me to fix this problem.

I ran a TB years ago (projection) and it was shorter than the eddy carb that it replaced.
just thinkin out loud if your TB was shorter than a carb like mine was and you ran a holley street dominator, maybe a 68 unsilenced or other round filter would fit under a stock hood

. The guy installing it has had it for 3 weeks. The car starts perfectly but once put into a Reverse or Drive it dies. I think he posted about it on here earlier this week.
