Series I 3800?
Ok, someone has recently told me that the 89 bonneville'* 3800...is NOT a series I engine... that it is an engine GM made inbetween the 3.8 and the series I ...and it has no specific name to it. So if anyone has any information with this... I would greatly appreciate it!

How do I explain this?
In the begining there was no such thing as a series I...
From 88-94 there was only the 3800 EFI , and later came the 3800 TPI<--- This was a small improvement on the first 3800...
You also had the L67 Supercharged known as 3800 Supercharged...
In 1995 the L36 came out names the 3800 Series II... The the Older 3800 TPI took on the name Series I... The 3800 EFI and the 3800 TPI are very close kin to eachother... The diffrences are minute... I can swap heads between the engine blocks... The TPI block used in the C and H bodies have a couplr more threaded bosses in them for diffrent mounting... But just about the same engine...
The series II was a complete redesign...
so yes the 3800 C is part of the series I family...
The 3.8 LG3 or Vin 3 3.8 V6 is not a 3800 series engine, even tho this is where the 3800 stems from... This would be a pre series I...
So in reality, it goes 3800 EFI, 3800 TPI - 3800 Supercharged , 3800 Series II-3800 series II supercharged
And if the 3800 EFI and TPI aren't alike, its amazing how my 3800 EFI has the exact same crank as the 3800 TPI

As others have said, there is really no such thing as a series I. Some people like to use that term, but it doesn't really have any solid definition. You could call a 78 231 a "series I"
if you want.
The series II came out in 95 and is a confusing term itself, since it'* more like the 6th or 7th generation of the Buick V6. Your car has the 3800, also known as the Vin C or LN3. Those are the correct terms, but you can call it a series I if you want. It was used from 88 to 91 and is very similar to the 91-95 engines.

Thank you much, that cleared things up! I am actually a Fiero owner, and I am swapping the Vin C engine into my car... Im just troubled with finding a Flywheel for it. I found a place that custom makes flywheels for the "series I" , but someone told me that It wouldnt be the same as a series I . Also, does anyone know of any flywheels that will fit the Vin C Engine, with out modification? (its a 6 bolt crank pattern) It was suggested to check out the 2.8, 3.1, and the 3.4.

The only 3800(that'* 88 and newer) that came with a manual transmission is the 95+(series II) Camaro. I believe this flywheel will work but it needs to be machined down because I believe it is too thick. Otherwise a 3.4/3.1/2.8 flywheel would work if you fill the holes and redrill them. This has been covered on several Fiero sites. Some even sell modfied flywheels.
There is no direct bolt on that will work.
