HMM ??? Im wondering if there may be mistakes there ? Only because we all know the LN3/C 88- 92 was SFI ? I also wonder what 92'* had the C ? Im also thinking something once upon a time made me think the L27 may have went into the Riv as early as 90 model year. I think it was a spec that just stated 170 HP for that year.

Also could this mean the 86 LG2 was the transition engine and then returned to the LG3 ? I dont like it. What was the source JR. ?

I know most of its irrelevent trivia with the LG3 and even now the LN3 C fadeing into molten heaven, but they were such great stepping stones to what the engine has become.

Good link Fuddy. Damn good.

This is a question we answered here the hard way, eh Jeffrey? Even the differences between 92 and 93 can be a PITA.

Depends on what years & Engine Series you want! Looks like most have been covered here nicely already though.

Comes in handy doesn't it Don?
Just wait until Don gets my other gift, then he WILL BE the Bonneville GURU!

As to your questions regarding the listings in the Factory Book....Well it only shows the years that that particular engine option was offered. This doesn't mean it was used mind you in any particular car, only that GM offered that engine...It can mean that that engine was for sale only too.

Great artical Fuddy !

So JR. what do you think about the MPI mentioned for the 3.8 ? I know the 3.0 and 3300 were MPI but I've always thought all 3.8 have been SFI since 1984.Does it mention the LG2 ? Are there any other codes for Buick V6 ? What about the 3 litre and the 3300 ? I've always wondered what the 3300 code was also.

Must just be misprint or typo. Ya gotta figure the people that do the books arent car or motor heads. They wouldnt even catch it when proof reading. I mean what car had the 3.3 or 3300 in 1985 ?

I read on the MFI once and (my memory) I think it fires 3 injectors at once and then the other three, thus multi point. So its less effecient and less complex computor wise but was said to be faster accelerating - do I believe it ? If so it could most likely be measured in 100ths of a second. I imagine it was just cheaper to produce.

So what was the RWD 3.8 codes ? What about the turbo engine ?

OK no more questions I am disapointed about all the use of the LG3'* and the LN'* I was hoping for a few more different codes to identify the even older FWD 3.8'*, now its just even more confusing.

Then I thought and would still almost argue that all 3.8'* were SFI.

Thanks alot JR you've been a big help at screwing up all I believed in.

I'd like to have a running bench display of all of them. Including a twin turbo Indy and the aluminum OHC engine I saw in a 85 Wildcat concept car. Then of course a car with each in it also. There was a 1985 2dr. Electra T-type that would have the dist. engine. That was a rare car. Nice interior but had the really square rear roof. One on E-bay last fall near Erie Pa but I just have too many already for the room I have.

Yea, I think the eightys were great years at GM. Fiero, new Vette, new Cam/Bird, the new FWD platforms, great body styling. Not over done, not lacking. Even the Berretta, the Cavaliers, how about the 89/90 GTP. I dont believe thats where they are today. Today they have a few interesting things and thats about it.
