I have the original build sheet for this car. Anyone else heard of this drive train combination? According to https://www.thirdgen.org/1983-pontiac-firebird it doesn't exist...

 

The chart doesn't specify combinations built for export.

 

Beat me to it.

I will also second Canuck car :-) lol

later

After '80 I didn't think GM used a non-CCC on passenger cars.And if the T/A is like the Z28 for '83 up the TH200C wasn't an option(but then again never say never with GM).
How long have you owned her?This might sound like a stupid question but does the build sheet's VIN you have match your car's VIN?It isn't unheard of for the wrong build sheet,or none at all,in a GM vehicle.

 

Yes, they did.

 

I thought '80-'82 was the change over years to computor controls for the distributor and carb on passenger cars.Now I know trucks,especially above a certain GVW,would/could be the one exception.Would export vehicles also fall under this too?

Aperion as to not change the topic of this thread would you mind PM'ing me generally what cars please.
Edit:Thank you for clearing it up for me.

 

Cars built for export were still available without computer controls.

 

Yes, it is a Canadian car, and has been in the family for quite some time now.

Here are the drive train RPO's:
LG4
MV9
MX1
N10
GW9
G80
NM4 (non closed loop emission system)
NM5
NM6

 

Well,as Apeiron pointed out,being an export car explains the why no CC for the carb and probably distributor.It's interesting an '83 T/A would have the TH200C(RPO-MX1)but with a 2.93 rear gear you wouldn't really need overdrive.At least you have positraction(RPO-G80)and not an open rear end.
And another GW rear axle code(GW9 - Axle Rear 2.93 Ratiouplicate of GU3).I know I've read the 9 bolt wasn't used until later but what rear end does your T/A(10 bolt,9 bolt or Dana 44)?

 

It has the 10 bolt rear end in it.

 

LG4 and 2.93 ?

doesnt exist according to this

I have an 84 K20 (3/4 ton truck) without a CCC, its GVWR is 8600. but cars are in a different category.

In 1983 there where 81 carbed 4 cylinder firebirds build for export.

 

yes trucks were different only because they were over the GVWR for emissions equipment requirements in some cases, depending on the year though


ive owned billions of trucks, lots have been over the GVWR threshold to where they didnt have cats or EGR or anyting except A.I.R. in some cases
even int eh 80s there were factory dual exhaust gasoline engine trucks with no cats and EGR yeah, like my 83 K-20 i had it was over that 8600lb threshold and had the HD emissions 350 code M

my 77 K-10 i just had it was just a half ton but it was the 400ci and was factory duals no cats and no EGR either all original stock untouched but the GVRW was over 6200 barely

cars no

cars were virtually all cat and EGR except in a few rare instances, some GM Quad 4 engines were non-EGR such as the 95 grand ams and so forth

apparently some engines ran so efficiently/cleanly that they were able to go without an EGR and the cat took care of it all


jeff whats your avatar from ?

thanks

 

It was available on export vehicles, Seems that with export cars, anything goes.


My avatar is from the 1982 Pontiac Merchandising Planer. It’s a window poster dealers would have displayed in late 81 to advertise the new model year.

 

The above observation is correct.

In Canada the CCC system was optional on all years of LG4 motors... Most Canadian dealers did NOT order this option.

I'm the original owner of a 1983 Z28. It was factory ordered in Feb 1983... It came with a LG4 V8 and a POS 200C three speed auto. In Canada, when I ordered my car, the 4 speed auto was not an option.

The Tech section also says that all 83 non fuelie V8s had steel hoods... Nope... My LG4 came with a plastic hood... and plastic hoods can be found on 1984s in yards up here too.

 

On the composite hoods for '82-'83 I don't know how Chevrolet determined which non-LU5 cars came with it.The non functional version shows up on LG4 and L69 cars.This is the first time I've heard of '84s having the composite hood.They may or may not be original.But with Chevrolet and being an export who knows.There was a recall that affected some late '82/early '83 cars(I had the plant and VIN sequence numbers but can't find it now).

That's an interesting note on the 700R4 not being available for '83 in Canada.So you were stuck with the TH200C but being the original owner is really cool.

On the EGR,as Randy82WS7 stated,some cars don't require an external valve but have the passages built into the intake(Dodge Magnum 318/360 '92-'01 are another example).

And on the axle code notice it's another GW and not GU code but it's identical for axle ratio.

 

Ya the car was (is) a graduation gift to me from my grandfather... Who was a major speed/performance nut.. He is gone now.. but the car lives on (in my front yard...) desperately waiting for a rebuild and some fresh paint.

I have all of the sales literature from 82, 83 and some from 84... I'll have to dig them out...scan them... and send them in for the tech pages...

I'm pretty sure that the plastic hoods on 84's Z28's up here were stock the one I scored at a yard (off of a white 84) had original paint.

I don't recall my car ever getting called in for the "composite hood de-lamination recall" I can't remember if this was a mandatory replacement or an inspection only thing.. This might have been a US only thing too... As the post above states on export cars... just about anything goes.

The plastic hoods do all kind of "dancing" over 100 MPH... I can understand why GM went back to steel... I have both a steel and a plastic hood for my car... and my 200C is in storage under my workbench I swapped in a 700-R4 about 10 years ago.

 

interesting thread,

ive only seen one glass hood so far and that was on an 83 Z-28 L69 auto trans i had for a bit


seems that anything goes for export


i believe it

... wouldnt doubt it
