seeing as how Chrysler B blocks have the distributor in the front; I modified a Chrysler 300 tach drive distributor shaft so that the FI fuel pump drive cable would turn in the right direction, then made a 6ft long drive cable that wrapped 180* around the top of the engine so that it could drive the pump.
I made an adapter manifold from square tubing and steel plate and had it surfaced flat for the doghouse to sit on. accelerator linkage was a cable on mopars so that wasn't a problem.
the FI gave then engine back low end the Stage III cam took away and I was able to change out the 4.88 back to the original 3.23 RER that came in the car.
as the FI was for a 283, it ran out of 'air' flow at about 6K, so that was it's Achilles heel; but it was awesome cool... I wish I did have pictures, I reckon people have a hard time believing it can be done. BUT, if there is a will, there is a way..

383 Chrysler Project
none that I can find, film pictures were expensive back in the mid 60's (for me anyways...)

hindsight being what it is, I have often thought of that. I guess my first thought was to accelerator linkage but now I realize I might have been able to get a longer accelerator linkage cable; BUT, remember, this was the mid 60s and a lot of the stuff we take for granted wasn't readily available. this was a shoestring endeavor....
second thought is as to whether the installation of the distributor could have been rotated 180* so that the modified drive end would be pointing towards the injection pump if the unit was mounted backwards. as I remember, mopar distributors used a blade type distributor drive; but I don't know whether they could be rotated 180* and put in backwards. it would have made things a lot simpler; but, surprisingly I never had a problem with a 6ft long drive cable...
the FI unit wasn't mine (and I have no idea what version it was), it belonged to a friend with a 58 corvette and it had to go back to him. over 50 years have transpired since then.... ain't hindsight and 'what ifs' great; there may have been other reasons I did what I did, just don't remember
given the parts and opportunity, i'd do it again from an older and wiser perspective. even my current modified EFI project was on a 'wing and a prayer'....
