How can you tell the difference between a series 1 and 2 (SC motors)? the blower is off of the motor , just a long block basically

Thanks!

Hmm, I don't know. I'm going to the junkyard tomorrow. I'll bring my camera with me and see if I can find a difference. Does it have the lower intake?

The ports aren't evenly spaced on the S1.

The old series 1 might use a stamped steal oil pan. The series 2 probably uses a cast al oil pan. That might be a way to tell that is if the series 1 used a stamped steal oil pan.

Its possible, but when making a crack about shauns missing details of what people said you mis-spell something, that would not make sense to me. Thats just how I read it.

Does the motor have accessories on it?

It was done on purpose :la:

If you haven't noticed, I am very meticulous about my spelling/grammar/word usage online. I actually spellcheck, and proof-read everything I type before I submit it. And if after submitting it, I see an error, I will go back and edit the post for that one mistake. Call me crazy.

your wrong anyway, s1 and s2 both had stamped steel pans.

Biggest giveaway is exhaust for me, they have goofy looking manifolds and stuff.

The biggest difference I can tell is from the supercharges on both the S1 has a smaller goofy looking one that has a huge plastic cover over it

The height and what dark says will be the only way to tell without the supercharger attached.


Anyway here's a pic of a s1 supercharged engine.

Supercharged, the easiest way to tell is where the injectors go into the engine. On Series 1, they are installed into the intake manifold. On Series 2 and 3, they plug into the cylinder head (and the valve covers are specially molded to clear them).

Exhaust manifold and spark plugs are the 2nd method. On Series 1, exhaust ports are not evenly spaced and all 3 spark plugs on the cyl head DO NOT sit at the same angle. On Series 2 and 3 engines, exhaust ports are evenly spaced and all 3 spark plugs sit at the exact same angle (per side).

Throttle body is the 3rd method of determining what version of engine you are looking at. All Series 3 engines have electronic throttle control; no cable connection, NO MAF sensor or IAC valve on the throttle body at all. All FWD Series 2 (SC and non-SC) have the TP sensor facing the front of the car and MAF sensor sits on the top of the throttle body. (NOTE: 1999-02 F-body 3800 S2 L36 engines had electronic throttle control). Series 1 versions have the TP sensor down towards the bottom of the throttle body and the MAF sensor sits at about a 45 deg angle split between facing forward of the car and up.

FYI:

The 3800 V6 first appeared in 1988; 8th vin C; RPO LN3. 165hp / 210tq.

In 1990, the TPI 3800 appeared (now known as the Series 1); 8th vin L; RPO L27. 170hp / 220tq.

In 1992, the 3800 SC appeared; 8th vin 1; RPO L67. 205hp / 260tq. In 1994, the 3800 SC got a supercharger upgrade boosting power to 225hp / 275tq.

In 1995, the 3800 Series 2 n/a appeared in some cars; 8th vin K; RPO L36. 200-205hp / 225-230tq.

1995 was the LAST YEAR for Series 1 3800's.

1996 was the first year for the 3800 Series 2 SC engine; 8th vin 1; RPO L67. 240hp / 280tq.

2004 was the first year for the 3800 Series 3 engines. SC version RPO: L32, 8th vin 4. 260hp / 280tq. N/A version RPO: L26, 8th vin 2. 197-205hp / 225-230tq.

2005 was the last model year 3800 Series 2 SC and N/A engines were used.

2007 was the last model year 3800 Series 3 SC engines were used.

2008 was the last model year 3800 Series 3 N/A engines were used.

My understanding is that only series 3 L32's come equipped with cast aluminum pans - as stated in the L32 upgrades brochure. 96-2004 L67 cars (1997-2006 Monte Carlo) are all equipped with stamped steel pans (like mine). All sighting thus far supports my understanding, so X; I'm going to have to assume your cast pan migrated from a S3 motor.

Nope, cast aluminum pans appeared on some C/H body Series 2's after 1999, IIRC. GM did this so they could use new engine mounting on these cars (motor mount bolts to oil pan and block).
