You won't find one because they never put FI on the 396 from the factory in 65. Small block only.

Where is this "History of the Corvette"? I'm not finding it. Can you post a link to it?

Ditto!
Now, with all of that said, in Ken Kayser's book on the development fuel injection, he does mention (with a couple of pictures) that there was a FI unit developed for the 396----------------BUT IT WAS NEVER PUT INTO PRODUCTION (it was strictly a prototype development)! And, until I read that information in Ken's book, I was never aware that even a prototype or experimental FI unit had been built for the BB.

Yep, pgs 441-442, but unfortunately, almost no details.
And not really surprisingly, there was apparently a prototype made for the 409 engine. I know nothing about that one, but apparently someone has, or did have, it on a 409 in a streetrod. I've only seen a couple of pictures of it when it appeared at car shows.
A few people here may (or may not) know that 57-58 Pontiacs also had FI, at least ONE 57 Olds got a prototype FI (pictures in Ken's book), and for many years there has been talk of five 57 Cadillacs built with FI (also confirmed in Ken's book) which was brought to light MANY years ago by Mike Hunt (now deceased as the result of a motorcycle accident). UNFORTUNATELY, none of the FI Cads are known to exist nor are there any known pictures of the Cad FI units. The FI Ponts are scarce today (they were scarce then, 600 in 57, 400 in 58) and very scarce today. The Pont FI units are a bitch to work on and NONE of the FI guys around the country want to touch them.

It is a garden variety 1963 "7375" FI unit. The venturi cone has been hogged out for more air flow and the Cranking Signal Valve has been replaced with a '64-'65-style starting fuel bypass mechanism. Both of these modifications were made by the owner, not RP.
To adapt it to the 409, the owner milled an adapter plate out of aluminum. This plate sits on a cut-down carburetor manifold and the FI unit attaches to the plate.

I would be reluctant to take one on. Just calibrating the air/fuel mixture would be a significant project.Oddly, there is a '58 Pontiac FI unit on the auction site even as we type.

I can fill in some of the blanks here because I rebuilt that unit earlier this year.
It is a garden variety 1963 "7375" FI unit. The venturi cone has been hogged out for more air flow and the Cranking Signal Valve has been replaced with a '64-'65-style starting fuel bypass mechanism. Both of these modifications were made by the owner, not RP.
To adapt it to the 409, the owner milled an adapter plate out of aluminum. This plate sits on a cut-down carburetor manifold and the FI unit attaches to the plate.
There is at least one existing '57 Chevrolet FI unit running around with a Cadillac air meter on it. The air meter has a unique casting number which links its origin to the Cadillac development program. The finish machining on the air meter was done to satisfy Chevrolet FI requirements.
I would be reluctant to take one on. Just calibrating the air/fuel mixture would be a significant project.
Oddly, there is a '58 Pontiac FI unit on the auction site even as we type.

A similar unit was designed for Chrysler in 57.

Gm built a few experimental FI's for the 348/409 that was built by Marvel Schebler. Unlike the Rochester it was a timed injection with a combination rotary fuel pump/fuel disrtibutor and individual injectors for each cylinder port. It was driven by a chain off the cam and a special cast aluminum housing was spaced between the water pump and the block. I have pics on my other computer,
