Out of the tranny shop tomorrow!
Had to rebuild the tranny. Wouldn't shift out of first, thought it was the modulator, then the valve body, then the drum.
Question:
I bought a factory service manual from Faxon Literature. I've got the 3800, but I can't tell if I have the I or the II series engine. Can anyone help me? Also, is the HP output the same for each series, and does anyone know how I can find the HP rating for my particular engine? It'* a VIN "C". Does that cinch which engine it is? The book says LN3 V6 3.8 SFI (SFI?) ((Sequential Fuel Injection))
Thanks
Mike

IIRC, series I didn't technically start 'till 92 so I'm not sure what the VIN 3, B, and C are considered.
LN3 V6 3.8 SFI (SFI?) ((Sequential Fuel Injection))
This is correct for a Vin C. They are rated at 165 HP.

yea you got the vin C. It is considered pre-series 1 but is almost the same thing. The only things that are different that i can recall is the intake manifold and a couple bolt holes. I believe the series 1 (L27) is rated at 170 hp though because of the intake manifold.

For a long time there was no such thing as a series I.... This is a hard thing to explain.. GM never called this series I or Pre Series anything...
You simply had the 3.8 V6, 3800 Series V6, 3800 Series Tuned Port Injection, 3800 Series Supercharged... Then the Series II came out and all of the sudden you had series I....
Technically the LN3 should be grouped in with the Series I... There were running changes to the block as GM went to the 1 piece rear main, and a cam and gear with a single bolt with no thrust spring/washer..
If you took the 1991 L27 3800 Tuned Port, and the 1991 LN3 3800.... They have the same parts through and through... The L27 had the benefit of an integrated PCV system, and the ability to breathe better..
The Vin C made 165 HP and 220 Ft Lbs
The Vin L made 170 HP and 225 Ft Lbs, the power curve was shifted up a hair...
Also, 1990 Was actually the first year for the 3800 Tuned Port, 1991 was the last year for the LN3 Vin C engine
