Default Identifying a 78

A 78 vette was found for sale by my nephew, out of state. Can anyone help identifying it from photos only.? I don't have the vin, the photos only at this time. Can the motor be detected L42 vs. L82 from the pics.? Also, can you suggest a reasonable price? It's been sitting for several years, don't know the condition of rust.TIA WB







Any info would be helpful!

based on the pictures it's an L48 4-speed

prive would be impossible to fairly determinr without a lot more, better quality pictures and plenty of info on options, condition of everything, especially the frame, birdcage, and body.
Even condition of interior and engine bay will be helpful.
based on those few pictures it could be worth $1k - $10k and anywhere in between.
Sorry, too many variables still unknown

Very good
The car is really light blue, but faded badly. Your right in line with the asking price! Also I can see that it has PW, PB, no air? Does the radio look stock?

ya No air, i cant tell from the photos but my best bet would be Not the stock radio, Non tilt Tele.. I would say 3k, 4k is high, but it matters, how it runs and drives and its problems....

All of the L82's had alluminum finned valve covers and a chrome air cleaner. Obviously, these items could have been changed, but I would bet the valve cover's haven't.

The L82 had "L82" emblem on the side of the hood,

It should have an L82 9:50 to 1 comression ratio emblem on console,

The tach will say L82 in very small letters at the bottom,

You can also tell by the VIN# if it's an L82.

Check the frame for rust and damage. What are your plans for the car?

I'm aware of the rust areas, but 3 states away. It appears pretty straight in the pic's. I'm thinking of buying it cleaning it up a little then reselling it.

I was told that it's fairly original, so your probably right about the valve covers.I don't see the other items that you mentioned either. Thanks

easiest way on a overall engine bay pic as you showed is that the L48's has the stamped steel valve covers painted engine color (blue) and a single snorkle air cleaner such as is shown in the picture.
The L82's has aluminum finned valve covers - black with bare silver looking aluminum on the top of the fins and a dual snorkle air cleaner.
Additionally, the air cleaner lid was chrome on the l82's instead of black on the L48's.

as a comparison, this is what a '78 L82 would look like - scroll about 3/4 th way down the page to see the motor pretty much completely assembled and installed:
http://69.253.166.197/page1/page127/...7/page157.html
see the differences in the valve covers and air cleaner betenn the L48 you posted and this L82?

As mentioned, there are other way to tell such as the VIN#, emblems on the hood, markings on the tach, etc but it was easy to see just from the engine bay pics what motor it was.

Great pictures thanks again Barry! Looks like your car has smog equipment on it? Should it be on the car I'm showing as well?

yes, my L82 has everything still on it but it's also a less than 10,000 mile car - currently only has 9,801 original miles. Everything has been left on completely stock.

if i'm not mistaken (which I may be but if so someone will correct me as they always do ) the '78 L48's except the california versions didn't have the AIR pump on the front of the motor like the L82's did. This would be the part mounted in the front, in the middle, between the alternator on the drivers side and the AC compressor on the passenger side.
This was part of the emissions package but because of the changes between the L48 and the L82 they were able to pass emissions requirements without needing the AIR Pump on the basic L48. California L48's and the L82's still had them though.

BTW, if your nephew is looking for a '78 Vette, my '78 L82 low milage car is for sale......

That's great info. My nephew knowing that I love vettes called with information on this car.My sister was having some work done to her car at the same shop. It's cheap in my opinion, and hasn't been offered to the public yet.
One question for you about your car, with such low milage why the rebuild? Sure looks like you did a hell of a job! WB

previous owner had the car since '97. can probably count on both hands the number of times he drove the car than basically got tired of it. The last few years he had it he also got tired f it sitting in the garage taking up space while he parked his daily driver outside so he moved the vette to the driveway and covered it with a plastic tarp and it sat there for a few years. Plastic tarps retain moisture so when I found the car it looked like crap with surface rust and oxidation on all the engine parts - no rust rot, just surface rust everywhere so I pulled the motor, stripped it down, refinished each part. than put it all back together. It was simply a cosmetic condition that required the work

Default L48

I say it is a L48, for the L82 had different valve covers and a different air cleaner. And back in 78 most L48's came with four speeds and the L82's came with an automatic, unless order differently.

In 1978, most Corvettes were automatic... period. Air conditioning was standard, as were power brakes and power steering. I have seen many L48's with L82 valve covers and emblems added, I've not yet seem an L82 with stamped steel valve covers and the emblems removed... but it's possible... Oh and many of the L48 4-speeds were Saginaw's...

Good luck with your find... a rusty birdcage and or frame could easily make this a parts car.

GUSTO

I was mistaken about air conditioning, it didn't become standard until part way through 1979. Approx 9,000 out of the 46,776 '78 Corvettes were ordered without A/C.
