1983 ...... and 1/2??
I have a friend who has a 3rd gen z28, he knows only enough that he can put gas in a car and it goes. He is under the impression from the previous owner that it is an '83 1/2 (
) model year, I have my doubts personally, so if it exists what would the tell tale cues be that set this one apart from any regular '83/'84? I found a site listing all years and their respective features, but the 1983 and 1/2 is conspicuously absent from record. is this just a rare care and little information is available regarding it's existence, or does it even exist at all? it has a crossfire injection 350 and is a base z28, has rear window louvers, T-tops with their shades intact.
But really......

Re: 1983 ...... and 1/2??
the previous owner was probably referring to the month in 1983 the car was manufactured.
like my car is a 1986 trans am but was made in june of 1986 so technically you could say my car was made at 1986 1/2
probably said 1/2 to tell your friend it was made halfway through 1983
it wouldnt be referenced in any book besides gm's production line archives
to the rest of the world if it was made sometime in 1983 its just plainly a 1983 car
the worring over the 1983 1/2 is just over thinking the age of the car
just tell your friend if he needs parts just say its a 1983 camaro z28
hope this helps

Re: 1983 ...... and 1/2??
it all depends how picky or precise you wish to be.
like at a car show,
if your car was made for the 1983 model year, then you call it a 1983 car
but you can mention that it was manufactured in october of 1982. either way its still a 1983 car
this kind of precise info is usually ignored or not known unless you have a "rare" car and you go to auctions or car shows with it to give the entire history on the car to get the most money for it.
i mean i dont know everything but that is my 2 cents on the subject.

Re: 1983 ...... and 1/2??
Also it's a 305 unless someone swapped in a 350 as the 350 wasn't available again until 1987

no, there wasn't a 350 available in a 3rd gen f-car until 1987.

Re: 1983 ...... and 1/2??
i think your thinking of the half year production of the old mustangs, back when there were in fact 64and 1/2 cars, but they have never done something like that with the thirdgens, or the second gens either, and i possibly the first gen camaros, but to my knowledge it was mostly a ford thing anyway

Re: 1983 ...... and 1/2??
My Trans Am was built in the 3rd week of January 1984, so it's either a 1984-3/8 (going by start of production in Sept. 1983) or if you go by calendar year it's a 1984-1/26th... or as I prefer to write it 1984.038461538 with the underlined part being a repeating decimal. 
No thirdgen was ever designated as a half-year model and the original engine in a 1983 or 1984 f-body was not a 350.

Re: 1983 ...... and 1/2??
The '70 is still a '70... its just sometimes refered to as a '70.5 because it was introduced very late in the '70 model year... about 6 or 8 mos late or something.
