Paid a visit to the GM Heritage Center
 

If you have questions about your car, I may be able to tell you what I found. My main interest was to learn more about stick shift cars but may be able to help with other stuff.

In the 1980 G-body model year, you could still get the 350 C.I. sbc from the factory in the station wagons and El Caminos. Is that true?

All it will show is "LeMans" and an option total. If you give me the option code, that will help

Can you look up Grand Am's if so how many V6 G/A's got made in 1979. Also how many had sticks or auto trans. Thanks, Tracy

For the LeMans (which includes the Grand Am), 453 had 4-speeds in 1979. 207 had 3-speed manual.

For the V6, 789 had the LC6, while 65,125 had the LD5.

I may have to eat my words, as I have another doc that may help.

If you give me the body code for the G/A, it'll help a lot.

2 door Grand Am is 2G27
Division: 2 = Pontiac
Series code: G = Grand Am
Body Style code: 27= 2 door (if 19 = 4 door)

After Body Style is the engine code: Y= 301 2 brl
W= 301 4 brl
U = 305 2 brl
H = 305 4 brl
A = 3.8 Buick

PHS for 79 Grand Am with a 301/4brl 4 speed has the codes:
L37 for the 301
MM4 for the 4 speed

It would be really nice to know for sure how many had the 4 speed manual, 3 speed manual trans and how many had the Buick 3.8 and even the Chevy 305.

I'm going down the list and organizing, and it seems earlier years are coming first. I'll eventually report back with anything new.

I've heard of a dozen or so 78-79 Grand Ams with the U code 305 (2bbl),
But never, ever heard of any with the 4 bbl 305.
Either it was a seldom checked option, or unavailable outside of California + high altitude states.

Here's something to whet your appetite till I get to the later cars.

1979 Grand Am

AG19
231-2 154
305-4 51
301-2 715
301-4 945
Does that total 1865?

AG27
231-2 212
305-4 62
301-2 1268
301-4 2478
231-2 (LC6, not sure how it's different to the LD5 above)...just one built!
Does that total 4021?

Wow! 231 equipped coupe is a one of one.:eek: Tracy, is that the car you had/have?
I briefly corrisponded with the owner of a '79 w/231 a decade ago on the GrandAmRegistry website. Said car resided in northern Indiana at the time.
That was the first I'd ever heard of a V6 2nd gen Grand Am.

Even more surprising is that total V6 production was 37% more than 4bbl 305.
<edit> I just noticed there are no 305 2bbls listed in that breakdown. Maybe that was a '78 only engine.

Diego, can you come up with the same breakdown for 1978?

No, read again.



I don't know if I have 1978. Will get to it eventually.

OK, I must have missed that.:o Late at night, and my eyes were playing tricks on me I guess.

That means 231 production was more than triple that of 305. Remarkable.

I'd like to see the number of bench seat coupes, or full vinyl top for 1978 GA, but I suspect that would be like 'splitting hairs'.

Here's 1978 Grand Am:



305-2
AG19: 221
AG27: 433

301-2
AG19: 1332
AG27: 2974

301-4
AG19: 1288
AG27: 4360

You Grand Am folks, please check the totals and see if they correspond to their respective published data.

Thanks for all of the data for these. All of the numbers add up to what I have seen.

Do you have any way of determining manual transmissions and the break down for the 1980?

Thanks for taking the time to put this together..

As I continue to organize, I will let you know.

But my guess is tranny production by engine is not in the data I have.

Here's some more 1979 stuff:

Power glass sunroof: 289
350-4 motor: 120
3-speed manual: 207
4-speed manual: 453
AM/FM with CB: 77
AM/FM Stereo with CB: 541
Rally Gauges and Tach: 2212

Can you give me the production numbers for an 86 Grand Prix? T-Tops, 305 V8, 4 speed overdrive auto, and bucket seats. I sure miss that car. Somewhere I read that like 3% of Grand Prixs had T-Tops.

As always, thanks for the info Diego.

Back in 1979, our next door neighbors, who were an elderly couple, bought a new 1979 Grand Prix SJ, two tone red. At the time, my brother had just taken delivery of his special ordered 1979 Trans Am Special Edition 400 4-speed. After a month or so, the couple next door asked if I could cut their grass while they were on vacation. When I went into their garage to get their lawn mower, I noticed their Grand Prix was a 4-speed! I was a bit stunned, because the couple were both recently retired, and this was the wife's car, who appeared very reserved and conservative (but their daughter, who was around 25-ish at the time, was smokin' hot, and the talk of the subdivision).

About a month later, the mom asked if I could look at a noise she felt was coming from under the hood (squeaking belt). I was again stunned to see a Pontiac V8 (301), and I don't recall if it was a 4-barrel or 2-barrel. Didn't think much of it at the time, but now realize how rare that was.

Diego, I take it the "350-4" number were the diesels?

I stopped at 1980.

Plus knowing the option codes would be very helpful.

And option combos are unlikely.
