I'm wanting to put a EFI throttle body conversion on my Dart with a 5.9 Magnum. I'm planning on driving this around the country so I'm concerned about the reliability of these systems. I really tired of carburetors after 45 years of dealing with them. I've use one setup that being an older Fast EZ on a customers car. We were really happy with the outcome. The two setups that I'm looking at are the Fast EZ 30226-kit and the Fitech Go Street. Any real life experience logging many miles on these??? Thanks

I've got about 800 miles on a Holley Sniper kit using their fuel pump. It's performed great.
Whoever's kit you go with though you should do an in-tank pump installation with some kind of baffle. This is especially important if this is a cross country cruiser.

For a little more change, the Edelbrock multipoint setup can be had for less than 2K. It features a single plane manifold. A specter tank from Rock Auto and you have MPFI computer controlled ignition and solid fuel delivery. With all the fiddly bits you'll need, It can come in comfortably under 2500.
No experience with it though. And, I don't know whether or not it batch or sequential fire.
At any rate, my research indicates that adding computer controlled ignition adds around $500 to any of the TBI setups.
Also, from what I've seen personally, the TBI's don't really like dual plane manifolds and you may need a single plane to be completely optimized.
Keep in mind though, I'm in Denver where single plane manifolds are basically useless with carbs if you want to do anything but buzz to the track.
The last one I wrenched a bit on was the single plane Magnum 380 crate engine. Wouldn't idle, stinky exhaust and weird part throttle behavior with the appropriate Holley, dialed in on a dyno. Fitech installed perfectly with a Tanks Inc. setup. The guy drives like a grandma and complained about the top end. Answer ended up being you need to drive it like you intend to use so it can learn, even if you only do WOT to impress your friends. The guy is very happy now, and even did the Central City Hill Climb, which is a reliability run with mostly traditional hot rods. Lots of flat head Fords.
Another guy is fighting with getting a Fitech running properly on a dual plane (mild 350 in a C-10). He sent the unit end for repair under warranty because of strange behavior, hasn't gotten it back yet but the guy is bummed because FiTech recommended a single plane intake to him and the current one is beautified to the tune of 40 hours of polishing and clear coating.
More info to digest. Good luck

BcudaChris I'm over in Grand Junction. I've been running dual planes on my street motors for years with no problems. The one EZ setup I did was on this 472 Hemi crate motor with a dual planes. The setup behaved very well. Started right up. Great idle. Crisp throttle responce. Ran great. No smelly exhaust and burning eyes. No fowled plugs. I understand that on a race motor a single plane is the way to go.

Shabby or loose wiring or connectors are the most common issues when things go bad. There's nothing more annoying than getting stranded by a lousy connection somewhere. True but being a retired Master Electrician wiring and connections usually aren't a problem for me.

I'm more concerned with failure of the pump, injector or controller.

I've been running a classic f.a.s.t box since 2009. It was 10yrs old tech at that time. Never left me stranded. Cheap walbro 255 pump hanging on the frame rail, noisy but keeps working. Street car.

I have over 100,000 miles on a holley projection, installed in 1996 has had one pump in the first year, one tps, one oxygen sensor. I know others have had disasters with these but I think you need a modern charging system to keep voltage high at idle, and good connections. My install is on a dual plane, frame mounted pump below tank, and the key in my mind is the 100 amp at 950 rpm neville alternator, it never low voltages at idle not the joke 100 amp factory case junk. One other item, I used the factory tank pickup, it runs dry all the time when low and the pump has never failed from that, it is a walbro. Low voltage kills these systems, I will go Holley for my next install.

I have four years and over 8000 miles on my system. No it's not a plug and play system, like you are looing for. But mine has given me no problems so far.
F&B throttle body with FAST EFI ECU.
