I came across a 1977 Caddy Seville in a boneyard the other day and found a complete working Bendis Fuel Injection set up on the Olds 350. It looks pretty simple to transplant. Can anyone give me any info on this set up? Any experience with it?

I don't know a thing about these except this: A couple of friends belong to the Cadillac club and own late seventies Sevilles. They've had nothing but problems with this fuel infection (mispelling indended) system and are constantly talking about converting to carburetors. In fact, there's apparently quite a cottage industry converting these cars to carbs. This tells me to stay away!<P>By the way, GREAT name!

I have a '77 Seville with Bendex fuel injection, that has been trouble free up to this point. However, anybody that I've talked to that has knowledge of these systems, has advised me to change over to a carburetor, if I'm planning on keeping the car for any length of time. Reasons given is scarcity and price of replacement parts. My problem is that nobody seems to be able to tell me what's involved in the changeover, let alone finding a place to do it. I'm lead to believe that it would involve more than just the fuel system itself, since an Electronic Control Module is involved.

One main issue would be future parts availability and their cost. The idle speed stepper motor is very expensive, or at least was several years ago. It could well have been discontinued by now.<P>It was a good system when new, from what I understand, and was very similar to what was on the Cadillac Eldos and Cosworth Vegas in operation. The design was reasonably solid as such, but the replacement parts issue would be one reason to not try to convert an existing Q-Jet equipped motor to the Bendix injection.<P>If fuel injection is your deal, then check out the Holley digital injection units with their own brain and feedback loop options (i.e., uses and oxygen sensor for all operation other than WOT). You would probably need a regular Olds carburetor intake manifold from the aftermarket as the Holley unit has the same bolt pattern as a 4160 Holley "square bore" carburetor. Parts availability and such should be good for quite some time into the future also.<P>There also might be some other possibilities with some of the fuel injection gurus, like Rance, that could graft a later model injection unit on there--for a price.<P>Enjoy!<BR>NTX5467

I considered doing this swap on my Buick, but I decided it would take to much customization. From what I have been told the Caddys had a sensor in the distributer to tell the computer when to fire the injectors. I have heard of people chopping the top off of these distributers and grafting them onto their non-caddy engines. <P>These systems are also not very tuneable. The only way to enrichen them is to wire it so that the computer thinks the car is cold all the time.<P>I went with Holley's Commander 950 fuel injection system, their top-of-the-line system. I would advise you to stay away. I started installing it in August, it took me a month to install in, a month to tune it, and two more months of playing with it to get it working good.<P>If I were to do it again I would buy a lower end system with simple tuning controls. Just make sure you get one that has an oxygen sensor so it can run in closed loop.<P>I get about 2.5 more mpg on the highway, while city mileage improvments are marginal. <P>If you aren't mechanically inclined, lazy, or poor then I would advise that you spend your money on a new quadrajet and have it tuned on a dyno. Their is still a lot of trial and error work in tuning fuel injection. The O2 just does small adjustments, it doesn't tune the car for you.

What engine Tomsriv?

I'll reimburse anyone for shipping their Olds injection stuff, including intake, to me. Contact me privatley. Thanks.
