Very cool. A truly 1 of 1 Shelby. It'd be interesting to see how well it runs.

I have a 4x6 foot blueprint of the Shelby EFI on my wall in the garage.  When guys come in and start looking, I usually point to my Mustang and it takes a bit until they realize I am yanking their chain.  :)

It was a sorta modern EFI system other than the "pumpolator" (their name for the regulated pump)

I say: Bullshit!  ::)

No way Jose. It's a modern system and is not from the 60's.

There does seem to be a lot of information on the net regarding The Conelec Company from NY who, back in the '60s, brought out an EFI system that was considered by Shelby.

I'll be damned! They did try an EFI system way back then.  Ken, you gave the name and here's the link:

Chrysler had EFI (Bendix I think) in 58 that they recalled because they could not get it working
reliable with the technology that was affable at that time. As i remember reading about it
long time ago Bosch bought the rights to it and came out with it on the
VW TLE in 68 or something. Thankfully they was not working flawless. So in the late 70s we could get non running TLE s for free to
get the engines for our dunebuggys. We swapped on our set of dual carbs and was king
of the sand pits, 1600 cc and 68 HP 8) ;D...I think i still have the carbs and intake in the barn somewhere

I'll take a picture and see if it will show up

40 years of doing Mustangs and I have never heard of the car.Only EFI car I know of is the green Shelby coupe EXP-500 that Craig Jackson owns and even it is missing most of its prototype parts....Has the serial number of the fastback been posted.

I always thought that the green coupe was the only one that had it, although I suppose more than one of each part was made, maybe someone cobbled it together?

   Lucky you didn't bet anyone! Pete Disher has painstakinly  reproduced a complete working system for this car. It runs as good as it did in '68. It has many "XE" numbered parts like the intake manifold ( cast iron CJ) and the exhaust manifolds ( unique different than "production" CJ manifolds.)  I supplied some of the parts for the engine.

Hi guys, I have been reading this forum since its inception but have never posted.  Lots of excellent info here for sure.

There is information indicating that Shelby planned to offer EFI as a regular option.  The records show 4 ‘68s, 13 ‘69s and 1 ’70 used for EFI development.  I think the ‘68s were all big block cars.  In ’69 there were a few GT350s but most were GT500s using (to the best of my knowledge) otherwise stock 428CJs.

Here is a poor picture of the schematic of the Shelby system I have on my garage wall.

Welcome to the forum, and that is really cool that Shelby was playing around with EFI back in the day.  Sounds like only two of the '68s retained their EFI stuff, how about the '69s?  Any info on what happened with those cars?

  Jay,
    Pete Disher has located one of the '69 350s that was Cleveland powered and had the Conelec system on it and I believe he's found at least one 500 too. His site noted above , has all the details. His research into the system and the cars that it was put on is second to none.

Looks like the "Little Red Shelby" has also been found.

Thanks for the welcome Jay.

My wife and I are fortunate to own one of the ’69 EFI cars, it’s the Grabber Yellow GT500 sitting beside the gold car in the video.  We are in contact with Pete who I absolutely agree is the expert on these cars and has put forth a ton of effort to recreate the Conelec system and support the EFI cars.  He has been generous in sharing information with us so that we can understand some of the history of our car.  I think he has found a few of the other ‘69s as well.

The information we have indicates that our car was converted back to stock (i.e. carb) after the EFI project and sold as a company car.  I don’t recall seeing evidence that any of the cars “escaped” to the public with the EFI system still in place so I suspect they were converted back to stock configuration like ours was.  I don’t think there had been a complete Conelec EFI system on a car for decades before Pete’s efforts.  A few of the EFI cars do still show evidence of the of the EFI installation – in our case there are holes in the driver side fender apron from mounting the pumpulator and bringing the fuel lines in (the pumpulator was mounted outside in the fenderwell), a plug in the gas tank filler neck from the return line, a plug in each runner of the intake manifold from the transducer (injector) installation, etc.
