I'm getting ready to pull the trigger on this.
I have the 289 4v in it now an dafter i figure out what transmision combo I'm going with the 347 goes in, it has a stout cam in it and I figure formeasy streetable driving EFI is the way for me.

Anyone have any experience with it?

Its not the system you're looking at, but my dad just put an MSD atomic system on his 70 Torino 351C 4bbl. He said he hit the key and it fired right up and idled really well. I haven't seen it yet but it sounds like it runs good! EFI has really come a long ways and can be pretty user friendly.

I put a basic FiTech (600 HP) system on Cosmic about a year and a half ago and still haven't got it tuned to where it is "user friendly". I was hoping that it was self learning, but doesn't appear to entirely be the case. I still need to pump the gas to get it to start, it runs rough off idle, and bogs at WOT. There are base settings that need to be entered into the system and some simple calibrations to adjust the throttle positioning sensor etc. In my case, I can't get the engine to run decent when I get anywhere near their recommended settings. Numerous calls to the helpline have not helped, and they are apparently overwhelmed with calls. You need to leave a message, and they might return your call in a day or two, not convenient while you are waiting with your head under the hood! I went with FiTech because of good reviews, competitive pricing, and wanted it to look like a polished carb. Personally, not happy. Take care! Cary

Seem's like I read about larger cam's with low vacuum not working with the Fitech system.

Based on reviews between Summit, Jegs, and here as well as some buddies, I ordered it....
All brands (Holley, Fast. and FiTech have mixed reviews. Car Craft just did an article on the FiTech and raved about it.
Ordered the fuel system too, so The car is still in the air after the last 3 weeks projects so I guess next time she hits the ground the mods to test will be
3:80 Trac loc
SS brake lines all around
TCI deep transmission pan
TCI transmission cooler
Rear discs
17X7 fronts
18X8 rears
and EFI

I expect it'll feel a little different

I have a 78 F350 with a 460. It was the worst starting truck I ever had. Set the choke pump the gas crank it over until it fired then pump and crank more and play with it until it warmed up. I installed a fast EZ-EFI. During the install I puled the IGN switch to gain access to wiring when I put the switch back and was installing the tumbler I bumped the starter and the truck was running and i hadn't entered the tune parameters yet. Even when it is below Zero and the truck has been setting for months all I do is turn on the key so i hear the fuel pump and then crank and the truck runs. No more long warm ups to keep it running I love EFI.
Only use the brakes to stop and get gas.

STPro,
You should bring that Mark 8 to Atlanta 11/11 for the SSHS17 shootout!
I will be there with my CTSV wagon

Got the system, pretty straightforward install.
Would be finished tomorrow BUT, imdecided to run the return into the tank drain. Went to pull the plug and with very little effort broke the brazing holding the drain bung.
I'm thinking I probably avoided a future leak, there wasn't much holding it in there

So I pulled the tank, going to try and braze the bung back on tomorrow, the tank is absolutely spotless inside.

Anyone else have this happen?
Tips?

That does sound like fun. Most of my summer projects will be out of the way by then. I will have to start working on my tune in the car so it could be ready in November

Hi Boatmangc and everyone else,

I just joined the forum today, and completed an installation of the Go Street 400 and FiTech frame mounted fuel pump on my 66 202 with a 289 on Monday. The engine would initially fire up and then die with a low battery. I charged the battery overnight and it fired right up yesterday. I adjusted AFR and idle a little bit (14.7:1 and 700 rpm) and then shut the engine off. When I tried to restart the engine immediately after shutdown, it would just fire once and shutoff. Once the water temperature went below 175, the engine started up. I'm going to play with it a little more this afternoon. From just idling, I am very impressed with the healthy throttle response and the robust sound through my Carven R mufflers. It sounds much stronger than with the Edelbrock 1405 installed.

I thought about using the drain plug in the forward right corner of the tank for a return line, but didn't. I instead cut my filler neck in three places, drilled a hole in the center piece, installed a bulkhead fitting, then pieced the tubing back together with filler neck hose and clamps. I plumbed the return through the original fuel line. I got the idea from the 2" Moroso filler neck return line kit I purchased that was too small. I'm leaking a little bit from the fitting, so if I can't get the leak to stop, I will get 90 degree tubing welded into that section.

From reading through various forums I'm finding that electrical connections, particularly the white wire to the key, are very important. I have also gathered that patience, research, and trial and error will be important to get this right.

Please post an update when you can.

Further update on mine:

I was not getting voltage to the ECU during cranking, so I ran a wire directly
directly to the ECU (white wire on Go Street 400) from the battery through a
toggle switch - it fires right up now.

I also relocated the fuel pump from just in front of the driver's side rear
wheel well to right in front of the gas tank and behind the differential.
I used an aluminum bracket that I had made several years ago for something else
along with a 90 degree shelving bracket for extra support and bolted them through
the the trunk. The pump is much quieter now.

The Good: The engine fires right up with no pumping and I can zip down the road
. with no warm up. My gas mileage is up from 13 and lower mpg to almost
. 16 on today's fill up - can't wait for the AOD or T5.
The Bad: Fuel sloshes around when low and can cause stalling and weird fuel pump
. noise - I fill up at a quarter of a tank now like I should anyway. With a carb,
. I had a slight, almost unnoticeable surge at idle in park; now the surge is more
. noticeable because the ECU is constantly compensating to remedy the problem

I have started isolating vacuum line but haven't found a leak yet.

Give us an update when you get it going.
