Just a few Q's

what was the 1/4 mile time of a stock 1984 H.O.?

how rare is a stock fiberglass hood on an 84? I just recently realized mine has one

does anyone have a pic of what the stock exhaust looked like?

TTA 1387

Mine ran 15.2 just like the brochure said it would.

Thought the glass hood was only for the Cross Fire? Mine was steel.

Exhaust was 2.75" with one muffler and 2 tail pipes. 4 bolt flange for the cat.

aciddrop2804

wow 15.2 stock? thats faster than i thought.

I also thought that the fiberglass hood was only on cross fires, but then I remebered reading a thread on here that said there were a few that were made for 84 models, but they don't have the induction flaps that open, just 2 metal plated bolted to the hood there.

i was looking for an exhaust pic. becuase i wanted to see what the tail pipes looked like. I thought mine were stock but mow i don't think so so I was just trying to figure that out.

As far as I knew the 84 z28 HO came with a 4 barrel 5.0. I think the HO part was supposed to be the fact that they came with 3.73. And I thought they did have the glass hood anyway.

aciddrop2804

the package was 3.73, a high output L69 with 190HP (as opposed to the lg4 with 150 HP) a dual snorkel air cleaner and other small things.

I know they didn't all come with glass hoods, just some, and I want to figure out how rare it is.

I have what was originally an '83 Z28 HO (L69) also.....I know, a year older - but it's even originally from Cincinnati!!

Differences between the HO and LG4 version for that year, the L69 had higher compression (due to different pistons), a better flowing exhaust with a 4 bolt corvette monolythic catalitic convertor, 3.73:1 rear gear ratio, dual snorkle air cleaner, more agressive fuel/timing curve. Not too any other differences between the LG4 and L69 I can think of. -Of course you had "5.0 Litre HO" decals on the front/rear bumpers as well as on the side rockers. - Also a HO dash emblem...

'84 L69 models were first year they offered the HO's with an auto trans. My car had a composite hood also, with non-functional flaps. Really not all that "rare"...they can be found. My original composite hood is collecting dust now, along with my air cleaner, ducts hoses etc...

I "think" the HO's did have the composite hoods in the early '84 model year until a recall for them came out in the midyear. The recall is posted somewhere on this board as I recall. The composite hood IS a bit lighter than the steel one.

All the rest of the '84 L69's just got the steel hood for the remainder of the year.

thanks for the thorough list. I'm glad i live in cincinnati being the birth place of the third gen camaro and all. Im supprised there arent more around here for that reason actually. And the hoods have to be at least uncommon, i mean they were only made for like a year. I would love to have another one. How are your flex tubes for the intake? would you be interested in selling them?

I grew up in Cincinnati, and I assure you that there were plenty of Thirdgens all over the place back in the day. Most rusted away and went to the junkyards. I'll agree the composite hoods are a little unique, but they can be found pretty easy....at least the non-functional flap ones.

I'm holding on to the intake system for now, since I have all my HO parts stored away.

The information here is different about the composite hoods from what I understood. From everything I've read the hoods were available '82 - '83 on all Z28's. The CFI cars received the functional version with the non functional on LG4 and L69 cars through '83. How Chevy mase the determonation on the LG4 cars is anyone's guess. There was a recall due to the hoods delaminating -separating - in late '82 or early '83 model run. I was under the impression they were discontinued after the '83 model year.

aciddrop2804

thats what i heard at first too, I didn't know about a recall though but mine is starting to seperate so that makes sence. apparently a few that were left over from the previous year were carried over to 84 to eliminate the stock of them I guess.

Hallsresto.com

my 84 also has a factory composite hood..non functional as also stated...

You still around? I have a 1984 Z28 that I want to get collectors plates for. Its all stock but I need the original stereo for it. I have found couple online but for some reason the opening seems bit smaller than what im finding. Just would like to know what the original stereo was?

jayslady707

I have the original stereo out of my 84' z28, that I wouldn't mind selling...

leoguy67

Not sure if you can post pics on here if so could you? And how much you want for it?

I thought I would chime in on this. The 84 Z28 H.O. had the corvette cat, higher compression, different heads, different cam, electric fan, higher hp(190 hp w/ 240 ft lb torque) and some came with the 3.73 gears(GT4 RPO) as well as a different exhaust. Trust me, finding the passenger exhaust manifold is almost impossible unless you know where to look. I am unsure about the hood because everything I have read about the L69 cars says the hoods were steel in 84 due to the hoods failing. Mine is steel, but it is a mid 84. As for the exhaust tips, I believe mine are stock and look just like the standard Camaro exhaust with a little bit bigger tips and that is from looking at my car which I was told by the original owner was stock. Also the L69s later in 84 came with a small in tank fuel pump to battle the vapor lock problem, while earlier ones had many different things added to them to help. I hope this is a little bit informative. Sorry I do not have pics of my exhaust at the moment.

'82 and '83 had the composite hood, whether it was carbed or Crossfire injected. The difference is the Crossfire cars got operational flaps rather than dummies. All '84 cars got steel hoods with dummy flaps, as there was no longer the Crossfire injection option.

My late 84 build HO has a steel hood..................

Other sites state GM quit using the composite hood in 83 and prob. had a
bunch of composite hoods left and just used them up till gone.

I doubt this is true. GM went to the steel hoods because of issues with the composite hoods, using up leftover composite hoods would defeat the purpose of tooling up for a new steel hood that would only get used for one model year.

I've had two '84 Z28's and both had steel hoods, and one of them was built very early in the production run.

sonjaab

Well then..........I guess the other posters who state they have composite
hoods must be LIARS or the composite hood fairy blessed their cars with
a "special" one off hood eh?

As we all know GM wouldn't use a BAD part on any of their cars and throw
away any leftover composite hoods instead of taking their chances and
using them up........................

Hmmm.........maybe I should RUN out in the garage and see if the hood fairy stopped
by and swapped out my steel hood?

marktex67

New member... found this '84 HO sitting in this exact spot since 1994. The hood appears to be steel and the exhaust appears to be stock, although you can’t see it very well. Don’t know the ET…
The only changes appear to be the later model spoiler, bra and ugly wheels. Pretty sure this is an '84...? It's for sale ($2,500 ... cheap?) and I'm looking to see if there's anything rare about it... I already have other project cars, so I'd need a good reason to buy it (like if it was one of the 11 '86 models!!). It's an automatic, by the way... What are your thoughts?

The car appears to be an 84, and 2500 would not be a bad price, we kind of need more info though. Does it run? is it complete? I picked up my both of my 84s for less than 1k one running and the other(current) needed to be put back together. So given what I see, I see a dirt covered incomplete non running car and would probably pay no more than 800.

FYI Here's a couple pics of my exhaust, also my 84 has a steel hood

Listen guy, you said "other sites" stated that the leftover hoods were "probably" used on a bunch of '84's. No need to get bent out of shape because I said that statement is likely an exaggeration of reality. While it may be true that composite hoods made it onto some '84 cars, that fact of the matter is that nearly all 84's (if not all) got a steel hood.

And yes, GM does in fact throw out a lot of body panels that are problematic. From now on it might be wise to have more than assumptions about assumptions to back up your insults.

sonjaab

86.......I guess your out TROLLINg today eh?
Maybe you should learn to READ!

I posted "OTHER POSTERS" not "OTHER SITES" report their 84s have composite hoods.
READ posts 1 and 11........................

86blackiroc

iTrader: (12)

I DID read and I see that you assume far too much. Both posts mention an '84 with a composite hood... that's all fine and dandy, but where is the info stating these are also original and documented cars?

I too have an '84 with a composite hood, but it came from the factory with a steel hood. I put it on there several years ago and looks right at home on the car which is otherwise stock. Anyone else looking at it would assume it's original, but it is not. Just like many other cars still around these days.

My other '84 Z28 also came with a steel hood, as did most (if not all) '84 Z28's.

What is your deal? Just because a member has one simple response that says their original car has a composite hood, you're going to take that as fact? I'd be rich if I had a nickel for every time some member says their pre-'87 car has a factory installed 350, but we all know those cars aren't real. Their owners might honestly believe, but ignorance doesn't make it true.

Get off your high horse and stop with the childish insults.

Enough guys. Any more and I'll close the thread. Thanks

I have a 84 z28 l69 with the composite hood. very very light compared to my 90 rs hood.

I had an 82 LG4 Z28 that had a composite factory hood.

My 84 L69 sports a metal hood and is original...production date 2/84.

Rat55chevy

My L69 1984 Z28 HO was ordered in November 1983 and delivered in February 1984. Built in Van Nuys with a steel hood.

BTW... I can find fiberglass hoods all of the internet. Cant find a Steel hood anywhere, especially rust free. I have two fiberglass hoods but cant bring myself to put it on.
