| The L67 engine began as the Series I Supercharged, one of the last versions of the long-running 3800 series of Buick engines that originated back in 1962 when the car maker unveiled one of America's first V6 engines, the 198 cid "Fireball". The design was created by chopping two cylinders from their innovative all-aluminum 215 V8 block. Since that time, the engine has evolved into the supercharged 231 cid (3.8 L) version that was used in various GM vehicles from 1992-1995. The Series I made 225 hp for 1994-95, and was replaced by the Series II beginning in 1996.
The history of the 3800 is significant because, due to the fact that it still uses older push-rod technology vs. the now common OHC (overhead cam) designs, the L67 makes a lot of low end torque for its physical size. Combine the fat torque curve with a supercharged induction system, and you have a powerful engine that can be made more powerful for relatively little money. On top of that, you can still have decent fuel economy, reliability, and drivability that is comparable to a completely unmodified engine.
The L67 was optional for the '95 Riviera, and was also offered as an option for the Buick Park Avenue, Oldsmobile 88 LS/LSS, Oldsmobile 98, and Pontiac Bonneville SLE/SSE. It was standard for the Bonneville SSEi. The Riviera is a G-body, a platform shared with the Oldsmobile Aurora, Buick Park Avenue, and Pontiac Bonneville.
Some performance engine parts designed for the Series II will fit the Series I, but there are many differences between the two, most noticeably the M62 blower used on the Series I vs. the M90 used on the Series II. There is still plenty of research needed to be done in this area. _________________ '05 GTO 6.0L • 6-spd • 95k miles • 0-60: 4.8s • 16.9 avg MPG • Nelson Ledges Lap: 1:26'95 Celica GT 2.2L • 5-spd • 165k miles • 0-60: yes'98 SC Riviera • 281k miles • 298 HP/370 TQ • 0-60: 5.79s • ET: 13.97 @ 99.28 • 4087 lb • 20.1 avg MPG • Nelson Ledges Lap: 1:30 3.4" pulley • AL104 plugs • 180º t-stat • FWI w/K&N • 1.9:1 rockers • OR pushrods • LS6 valve springs • SLP headers • ZZP fuel rails KYB GR2 struts • MaxAir shocks • Addco sway bars • UMI bushings • GM STB • Enkei 18" EV5s w/ Dunlop DZ101s • F-body calipers EBC bluestuff/Hawk HP plus • SS lines • Brembo slotted discs • DHP tuned • Aeroforce • Hidden Hitch^^^ SOLD ^^^ '70 Ninety-Eight Holiday Coupe 455cid • 116k miles^^^ SOLD ^^^

| You should be able to use any SC 3800 Series 1 motor from another GM. Bonnevilles and Park Avenues are good donors.
You could convert to a non supercharged motor, however there would be some wiring differences as well as a different pcm. | |

| It's going to be ALOT easier to swap motor for motor if you can even though the others would work. | |

| According to Hollander....
1995 Bonneville, Eighty-Eight, Ninety-Eight and Park Avenue supercharged engines will fit, as will the non-supercharged engines though you may have to swap the intake manifold and flywheel. | |

| The non supercharged engines have different rods, pistons and heads. The block is the same though. | |

| The 95 Riv has the Third Generation M62 supercharger. It has the Epoxy coated rotors and displaces 1 litre of air per revolution. The M90 displaces 1.5 litres of air per revolution. You can tell if the M62 supercharger you are looking at is a second or third generation by looking at the ridges that go across the top of the housing. The second generation has ridges that go all the way down the side, whereas the third gen (found in the riv) they ridges stop part way down. Also the third gen M62 found in the riv has a 2.8" stock pulley size where the second(being less efficent) has a 2.55" stock pulley.
So in short, the 95 ric has the Generation 3 Eaton M62.
edit: ah not fast enough.. lol _________________ | |

| In '95 the supercharged motors are S1, the N/A motor is S2. Does it have a supercharger? | |

| without more information I have to make some assumptions. 1) that you have a Riv, 2) you have a Series 1 engine and therefor 3) it is supercharged. So your supercharged S1 options are a little slim, but possible to find. pre-96 Park Ave Ultras, Bonneville SE, Some olds (88LS, 98?). got the supercharger as an option. | |
