fuel injecting the cleveland.

I'm using the EZ-EFI 1.0 TBI. There is a learning curve, but once you get it set up, the benefits are worth the price. No vapor lock or fuel boil on hot days. Change the tune on the fly. Instant throttle response. Instant starting with no pumping. Fits any 4 barrel intake. Increased fuel mileage. 1000 CFM, so no compromise between driveability and peak performance.

You MUST have a leak free intake and exhaust for the wide band O2 sensor. You also need to plumb a return line and high pressure pump & regulator. Ideally, the conversion should be done with the motor out of the car so you can do the plumbing and wiring right.

Fuel pump

There are two basic kinds used. The ones that mount on a regular intake are TBI (throttle body injection) while the other choice is high-pressure multiport EFI. The Weber-lookalike systems are of this type. Several owners from different countries run an adapted Ford EFI brainbox from Ford for a 351-W. The intake most seem to prefer is the aftermarket TrickFlow, which fits a 351-C block (with some machining) and clears the early engine screen. The quiet Ford factory in-tank fuel pump also fits in a Pantera tank with no cutting. If you have a '73-up or use a late sender with the built-in fuel-out in an early tank, the tank's fuel-out can become the fuel return with no cutting or welding needed.

While all this certainly works, you must know what you're doing in choosing your parts: injectors, lines etc. One local Pantera owner now has 10 yrs and 25,000 miles on his adaption, and a dyno test showed 450 bhp & 22+ mpg. He drives it everywhere, is enthusiastic about the factory stuff and readily answers questions.

Trick Flow now makes several bolt on FI intakes for the Cleveland.

Check this thread for some info on the Trick Flow manifolds.

I like the features of Pro M racing system. It is a bolt on multi port for our Cleveland. They formally used the Ford ecm but now have there own. They were formally known as Mas-Flo efi. Still owned by Chris Richards.
They are the only system I know of that uses mass flow to control fuel vs speed density.

Expensive but roll your own isn't cheap either. (The fuel pump and hardware are extra.)
I found this site years ago and some may not have seen it, but this Pantera guy is determined!!!!

If anyone has tried the Pro M system please comment!
Also a stock charging system is marginal , the EFI system with a full time fuel pump adds 10+ amps and the injectors and computer a little bit more.

Absolutely. EFI needs good voltage. I have a Powermaster 140 amp unit, and it will supply 13.8V with AC on, all fans running and headlights on. A great alternator, but you must bypass the ammeter with a volt meter, and run a jumper from the alt to the battery + on the starter solenoid.

Done like dinner.
Expanded scale volt meter , new gauges and a new fuse block from Pantera Electronics. New gen 3 alt from PA Performance. Relays to relieve the ignition and rockers switches.
Retired electrician that wants efi.

Can you elaborate on the use of the 'Quiet Ford intank fuel pump' fitting into the factory Pantera Tank?
I've been running an MSD Atomic EFI using the factory fuel sender and an external Wahlbro pump (I know it's supposed to be bad to draw from the top of the tank with an external pump, but it actually works great). I'd love to find an in-tank pump that would work though!!
Any details on that pump would be appreciated, part numbers, donor car etc.
Thanks

I run a tuner-carb but as an experiment a decade ago, I adapted a stock Ford TBI in-tank pump ('87 Ford 1-ton pickup) to our '72-L. Ford pumps are rotary-vane and small enough in OD & length that they drop right into an unaltered fuel tank. They are found on all Ford cars & trucks since about 1980. Just be careful- a TBI pump runs at 8-12 psi (which I regulated down to 7-8 psi for my Holley). It looks identical to a Ford EFI pump which runs at 42-58 psi and CANNOT be regulated down far enough for a carburetor. And once out of a donor car, you cannot tell them apart until they start pumping. There are no tags & stencils would not withstand gasoline.

The advantages are: the pump runs cooler when submerged, and the liquid surrounding it drops the pump noise to almost nothing. Third advantage is, NO plumbing adaptions at the tank. The mechanical 'adaption' is simple. You measure the pump length, then shorten the fuel-out line on the '73 sender by that much plus an inch or so, and attach the pump with good worm clamps & fuel-submersible hose (NOT the same as fuel-resistant hose!) The pump comes with a filter that snaps onto the pump bottom- it sets loosely on the tank bottom.

Electrical adaption means drilling another hole, then add a second stock female spade-lug to the sender top, and extend both wires inside down to the new pump. I scavenged a spade pug ass;y from an Alfa Romeo. I now use the fully functional pump as a primer-pump for the carb, but some day I may find a complete Ford EFI system to play with. Note that this adaption, like a hundred others, was written up in the POCA Newsletter at the time I did it, with photos.

Aeromotive actually makes a regulator specifically for this sort of thing. My recently sold NASA American Iron race car ( 1994 Mustang Cobra) used an upgraded stock pump with the Aeromotive regulator and a Holley carb. It has run since 2005 like that ( 400rwhp)with no issues.

As part of my 4.6L modular conversion ('99 Cobra Mustang version) I put a stock Cobra fuel pump (and the filter) in the tank. To do that, I cut a hole in the top of the tank (http://home.earthlink.net/~rlbpantera/catpix2/GasTank.jpg) so I could slide the pump onto a piece of alu angle iron welded to the bottom of the tank. More details and pictures if you are interested.

I'm running the FAST EZ-EFI 2.0 with the Pantera Electronics EIC. This system works great and no laptop tuning. You have to run a return line with the fuel system. They offer both in-tank and external fuel pump kits. I'm using the external fuel pump.

Use can see the ECU better in this picture.
