Engine and Transmission Tech

I am sure this question has been asked before but what would be a good EFI to put on a Ford 302 crate engine I have a Summit Racing carb on it now but would like to upgrade it to EFI. I was looking at the FITech [fitechefi.com] the price looks good but not sure if it worht the money or spend more for a diffrent brand.

Thanks

FiTech is what I've been watching. The Go Street EFI- 400 seems to be a lot for the money & reviews from folks who've used it are positive. If you want timing control too, you have to step up to the Go EFI 4- 600.

I'm not ready to switch yet so I've not researched but you'd want to be sure the sensors are readily available parts you can get at any parts store in case one goes out while you're away from home. Also, you'd want a plan for dealing with the situation the ECU went out on the road too. Not sure whether they sell spares or how much they are. Maybe packing the current carb as a backup for long trips would work.

I was thinking the same thing keeping the old carb as a spare in the trunk.

Was also thinking about the Fuel Command Center and mounting it to the battery compartment and moving the battery to the trunk, that way I can run the old fuel pump to the Command Center and vent it easier to the fuel tank and if the EFI goes bad i can put the old carb back on and bypass the high pressure pump.

Moving the battery to the trunk increases the polar moment and the center of gravity of the car. Why not use the space on the other side?

Its a 1980 single battery shelf has no lid on the drivers side would have to cut it out and build something for it, maybe i can move the battery on top of the back shelf in the car and then mount the command center in the battery well behind the passenger seat.

I would leave the battery in it's original spot Abe.
Precisely for the reason that Jim stated.
The stock position is nice and low and relatively central for something that heavy.
And it offsets the weight of the driver to some degree.
That means that handling is compromised if you raise the battery and move it rearward.
Safety is also a concern.
As most will mount the battery in a plastic "marine" box that will not contain the acid and lead filled bomb during an impact.
The use of the fuel command center is also problematic to me.
I would place it in the marketing gimmick category.
Using it now means two fuel pumps and associated wiring, a split high and a low pressure system, additional fuel lines, venting and mounting brackets.
Simply using a high pressure pump and a return line would seem to be easier and far more reliable.
Throttle body fuel injection like the efi400 is a transitional system.
It's marginally better than a carb. but not as good as port injection.
The OEMs used it for a very short time, mosty for cost savings, but also due to the slow ECU speed of the day.
It certainly has it's place, but by the time you've installed it you've already done 75% of a full port injection system, so why not finish it and reap all the rewards?
I would give a good long hard look at the stock Ford EEC IV system.
It fits the vehicle.
It's cheap as chips in the wrecking yards.
It's dead nuts reliable.
It's tune-able, with huge aftermarket support.
Parts are available at any corner store.
No matter where you go you're probably only a few feet away from somebody who can fix it.
And many on this forum have used it already so help is just a mouse click away.

So once again, there's my scotchy scotch induced ramblings.

Live like you mean it.

Fred, great info. To start with (and to start simpler, let's assume he wants to control fuel only. What else would be needed to make it work with EEC-IV?

EEC-IV computer
Throttle body
Throttle position sensor
Port injection intake
Fuel rail
Fuel Injectors
High pressure fuel pump/system
Crank trigger
Crank position sensor
Cam position sensor?

I drove an 86 Mustang GT for many years. It had the speed density system. Aside from the TFI on the distributor, it was reliable. That car got over 25 mpg on the highway with the T-5 and 2.88 gears. I loved the torque of that combination and I would use it on another stock-ish 5.0. I think the heads were a large part of the torque and economy of that engine, the E6SE heads. An alternate head would be the F7TE 'GT40p' head.

Two words of warning about the SEFI systems - don't use an under-hood air cleaner on either speed density or mass air, and don't use a K&N air filter on the mass air system.

I have a Rover 4.0 engine for a project and think it would be nice to stroke it to near 5.0 liters and adapt the Ford SEFI speed density system to that engine.

I had an EEC-IV/SN5/TwEECer system when I first injected my blown Olds 215. Had a surge at 2000 rpm I could never get rid of. I did use a K&N filter though, maybe that was it.

I was doing a little more research and looks like the Holley Sniper maybe the way to go it's in the same price range as the Go EFI 4- 600 and not sure how long FITech has been around.

Still TBI and as Fred says, a compromise between carb and port Fuel Injection. Would be easier as they are all in one with ECU.
