I don't know what the percentage is, but mine is a 403, so I'd certainly be
interested in hearing about it. Besides, I don't know why the same EFI
couldn't be made to work on a 455 with a bit of manifold work. Use a setup
from a 77-79 425 CID Cadillac or a 76 500 CID Cadillac.
Olds 350 with Bosch F.I. was used on 75-79 Seville and 79 Eldo. It shouldn't
be too hard finding such a setup. I had a couple of them in the 70's and
80's; the same basic system was used on Cadillac 500 CID in 76 as an option
(had one of those---ran great) and on the 425 CID that replaced it in 77,
also optional (most were carbed.)
Someone tell me why we want to use a different ECM with these when the
original worked pretty darn good. Granted, they were analog instead of
digital; so what? It monitored manifold absolute pressure, barometric
pressure, throttle position, engine speed, coolant temperature, and manifold
air temperature. It integrated all of these to determine the duty cycle of
the injectors. Quite a sophisticated system, and I thought that they worked
awfully well. My 79 Eldo would consistently get around 20 mpg on the road
without benefit of an overdrive transmission. My 76 Eldo didn't mileage
quite as well, but for a 9,000 pound car (seemed like it anyway) it did
rather well, and launched like a bottle rocket.
If I had time (not right now, unfortunately) I'd love to try one of these
Bosch systems intact on my 78 PB. Back in those days the ECM didn't do
anything else, so it should be pretty simple to install.
I still have a factory 76 Cadillac shop manual somewhere. If I can dig it
out I'll Xerox the applicable section and send it to Billy; I'll bet he'd
scan it and post it for everyone.
