Technical Mystery 1960's or 1970's Fuel Injection

I came across this fuel injection unit on an ***ignment and I would like to help the customer identify it. The original owner of the unit worked with/for Mickey Thompson and I wondered if it was a prototype? Any ***istance will be appreciated.

‘57 Pontiac Bonneville, only 630 Bonnevilles built that year. FI might
have also been available in ‘58.

 

Thanks Fordors - I looked it up and I think it's a '58 Pontiac FI unit.

 

And about as rare as chicken lips too!

 

From what I can find on the internet only 200 Pontiac Bonneville's with fuel injection were built in 1958, all were convertibles, all with a special code on the body tag identifying them as fuel-injection vehicles. Because of drivability problems most fuel-injection units were replaced with a more consumer-friendly manifold and carb, the problem being everyone held on to the fuel injection unit but wore out/wrecked/s****ped the car so there is a good chance there are more fuel injection units than there are cars to put them in. In other words what you have is a rare part that perhaps nobody needs.

 

here are a couple of the pictures, just for posterity....

 

The Chevy FI had some issues but from what I know they did overall function well enough…Why would Pontiac give up considering they should have had the access to same Rochester engineering ?

 

There was one in Port Arthur Texas. Oddest thing ever. A bunch of people were gathered around it listening to it. It whistled like a steam kettle. It was covered all over it so you really could not see anything. The Chevy units did not whistle.
