Re: 1991 z28 5.7
Its a nice car but not really rare. The thirdgen convertibles were V8's I believe.
The top engine that you could get in a thirdgen convertible was some form of the 305 such as the LB9, L03, LG4.
From '90-'92 all L98 cars had the G92 performance package. This included the dual cat exhaust, 3.23 gear posi rear end with the L98. Also for '90-'92 IROC's and Z28's with the L98 were only available as a hard top like the other poster mentioned.
With that being said there were not a lot of '91-'92 Z28's made in the first place. With only a little over 100,000 miles and its a 21 year old car, thats low in terms of miles.
Can you post some pictures up of the car?

Re: 1991 z28 5.7
Look in the consol or in the trunk lock box. All the RPO codes for the car should be there. Look for the code 1LE.
The easiest way for us to figure that out is if you have a 1LE (if your car is still mechanically stock) is to tell us if your car has air conditioning or not.
3rd gen 1LE's didn't have air conditioning installed from the factory. You would also have the twin piston caliper 11.86'' front brakes. All non-1LE cars got the standard single pistion 10.5'' front disc brakes. The car would also not have fog lights installed in the grill either. Those are some things to look for when someone says that they have a stock '91-'92 Z28 1LE.

According to Compnine, No 1LE.
The car also fails the other tests, it has A/C (RPO C60) and fog lights (T96)

Re: 1991 z28 5.7
To give you some perspective:
There was at least 352 with ALL of the following
81U Red Exterior
19C Black CLOTH Interior
L98 350 Engine
G92 Performance Axle (I think by 91, all of them had this)
Z28
With that said, there was only 99 of the above sent to California Dealers.
The car is not "Rare" by any stretch, however a nice find regardless. Enjoy it, have some fun.

Re: 1991 z28 5.7
I like this thread. This gives us all a chance to go over 3rd gen history and educate an new member.
I was a teenager when I first got in to 3rd gens and I read every book or magazine article I could find on them.
I can't tell you how many people I have meet that have no idea about 3rd gens or over look them. You can do a lot to these cars and go crazy with mods or keep them stock and enjoy them that way to.
KG427KG427 stay on the site and keep asking questions. You will get your 3rd gen questions answered here.
Did you take any pics of your car yet? Ha ha we all have been talking about it so much it would be good to see it.

Re: 1991 z28 5.7
You do not have a 1LE. How ever someone could have done a 1LE brake swap. Its a somewhat popular swap because you can have better brakes and the stock wheels still fit over it.
Your car isn't super rare but it has some rareity to it, It's a 350 car and thats always a little special. Actually all of our cars Have some rareity because of cash for clunkers and cars that were destroyed via accident or cars that were to far gone to be saved and have lived on doing service in other cars

Re: 1991 z28 5.7
I have the same one only 6,000 1991 z28 hardtop 350 only automatic that year were made. Think about it 6,000 back in 1991 how many are lost and wrecked plus half of them don’t have rear brake disc only some have brake drum because they run out of brake disc for them, so I’ll say that’s unique. My guess there are less than 2000 of 1991 z28 350 l98 with back brake drums out there guess🤷🏻*♂️

Re: 1991 z28 5.7
well mine is a 1991 Z28. Blue metallic and mint body and undercarriage is 0% rust. I mean NO rust what so ever. It has 1LE components including heavy duty sway bars and differencial with a baffled gas tank. Corvette brakes qwth a hydraulic hand brake.Turbo transmission etc. And it's NOT the 1LE because it's fully loaded. A/C. Electric mirrors. Power motorized trunk. Auto transmission. Upgraded sound system. So. How rare are our cars?? 1048 made that year. 1LE had only 478 made and had to be special ordered. I'm finding out as we speak how hard it is to find a 5.7L engine for replace the block and heads. Looking for a good used engine because rebuild is WAY too expensive. New is over my budget. Try not to break your side mirrors because they are non existent anywhere. Mine are in perfect shape though. Just letting you know our cars are valued high. My insurance company...Hagarty. .. told me to insure my car...as is in fair is worth minimum $23000. In mint condition and with low mileage.. under 200.000kms or 140.000 miles is low. Excellent condition is worth $32.000 to $50.000. That's realistic especially a hard top is worth more. Like mine. Blue metallic paint is rare. To have a fully loaded Z28 performance package with 1LE is even more rare. We have an investment car. Don't swap after market parts like mine also has a mint condition original steering wheel. Original refurbished wheels powder coated with silver metallic paint. Painted the wheel wells blue with a hardening clear coat. All rubber and aluminum trim replaced. Etc. Mint is mint. Not a numbers car but kept everything to original. Yes our cars are very rare.
Re: 1991 z28 5.7
Most 1991 cars had the baffled tank and the 700r4 trans is not a turbo transmission. Also, what constitutes "Corvette Brakes"? The 1LE did not use Corvette brakes to make it a 1LE.

Re: 1991 z28 5.7
I think he was joking. GarySauve got very little correct in his post. You called out the "Corvette Brakes" which don't exist. And he also mentioned a hydaulic hand brake, which does not exist. He also mentioned that he has 1LE components but his car is not a 1LE, my head is spinning.

Re: 1991 z28 5.7
Ok. Guys. I'm going by what I was told. Yes my brake rotors measure 11.75 inches in the rear and front rotors measure 11.25 inches. Not the regular 10.66. My transmission was changed by the previous owner. He told me it was the one that the 1LE. Came with. Yes my hand brake has no cable. I never said my car came from factory the way it is. The previous owner is the one who gave this car a new floor and changed everything to what the 1LE had. So sorry to all of you. I'm going by what a knowledgeable machanic showed me. If I do go to an Ottawa show then I can be lessened that I'm wrong. Or you can be amazed like everyone who's seen it so far. I was told if I wanted new rotors I'd have to get the ones that corvette has because 11.75 inch are hard to find. If I'm wrong it's because I'm relying on what I was told.

Best to just start all over admitting to yourself you have a highly modified, non-original Camaro. Then you will be okay here and probably find yourself very much welcomed. Lots of people like you on this forum. Good place to learn.

Re: 1991 z28 5.7
Yes. I'm sorry if I started something to cause trouble. I realuze I was in the wrong thread. I've owned this car for 10 months now. Knew very little about it. I'm learning much information that is reliable and up front. I like seeing people have the passion they have with your vehicles. Again I appreciate the feed back and I do apologize. Be safe.
