Seven Hills Motorcars is proud to offer this completely numbers matching 1978 Silver Anniversary Edition Corvette in stunning condition and priced to sell with only 24,105 original miles. This Silver Anniversary Edition is very original and truly an investment grade classic. The car is totally solid with great lines and is rust free. It runs well and drives great. The Corvette is finished in the beautiful and highly desirable color combination of RPO B27 Silver Anniversary Two Tone (13, 07) over Mahogany Leather (762) interior, which is the correct and original color combination as verified by the codes on the trim tag and build sheet, both pictured below. Most Silver Anniversary Edition Corvettes came with Oyster interior. Mahogany is much more desirable and rare. This is an excellent opportunity to own a wonderful classic Corvette that is ready to be used and enjoyed at an unbeatable value. One could easily buy this car now and sell it for more than the purchase price as the market on C3 Corvette is hot right now and on the rise. The low mileage is supported not only by the condition, but also the documentation included with the car and the clear Ohio title, pictured below, showing the mileage as, "Actual." Please peruse all of the photos, numbers, and video below to get a true sense of how original, correct, and nice this Corvette really is.

The previous owner of the car purchased it in 1985 with 15,286 miles. This information is verified by his Bill of Sale for the purchase of the car from Rice Chevrolet in Woodsfield, OH dated March 9, 1985. The previous owner's name was Peter Weber. His name appears on that Bill of Sale and on current title as the previous owner. There is also a receipt from 1985 included with the car showing the car had 15,890 miles at the time, which is another nice verification of the original mileage. It is very rare for a C3 Corvette, but a portion of the original build sheet also comes with the car and is pictured below. The paint codes 13 for Silver and 07 are present and clear. These codes are exclusive to the Silver Anniversary Edition. Also, legible is the 25th Anniversary option and D84 for two-tone paint, also exclusive to the Silver Anniversary.

Please notice that all 1978 Corvettes wore the "25th Anniversary" badge. However, only certain cars, such as this example, were the actual Silver Anniversary Editions with the Silver Anniversary regular production order (RPO), "B2Z." This is verified by the trim tag that is pictured below showing the paint to be 13 for the bright Silver upper sections and 07 for the Dark Gray lower section, which was only used in 1978 and only for the B2Z Corvettes, on the darker lower portion.

This Corvette is completely "Numbers Matching" and virtually every part we checked on the car is correct. We have run the numbers on hundreds of Corvettes and there are very few that are so many correct and original components with correct numbers and dates. The last six digits of the VIN are stamped on the engine pad, which is pictured below, and the engine is original to the car. The transmission is also original with the last six digits of the VIN stamped on the main case and pictured below.

As a side note, this Corvette is not a dealer auction vehicle.  We hand pick each car after careful inspection.  Our Corvettes come from owners who expect their car to go to someone that will give the vehicle the same care and attention as they did.  We invite and encourage you to examine the car in person or have the car inspected.  Please take the time to scrutinize each picture.  We photograph each vehicle to the greatest extent so you can feel confident about your purchase.  If you have a question about the Corvette, just give us a call.

 

model description
 


Chevrolet marked Corvette's 25th Anniversary in 1978 with the most extensive redesign of the car since the introduction of the C3 body style in 1968. The new Corvette introduced a large fastback style rear window that drastically increased luggage space in the rear compartment behind the seats. The interior of the 1978 was also significantly redesigned. The speedometer and tachometer were redesigned in a more square and vertical mode. A glove box was added on the passenger side to replace the pocket. The door panels were also completely new and included screw on arm rests to replace the molded style that been the standard since 1965. 1978 Corvettes featured special 25th Anniversary emblems specific to that year.

numbers

 


Please note when checking the numbers that not only do the correct stampings and casting numbers appear on the parts, but all of the dates are also chronologically correct. This means that all of the parts were made and assembled in the correct order. For example, all of the dates for the individual engine components and the engine casting date should obviously precede the assembly date of the engine because the parts had to be produced before they could be assembled. Most of the parts I checked follow this rule and are dated correctly.


item number description*
VIN 1Z87L8S435624 The first digit, "1," indicated the Chevrolet division of GM.  The "Z" is the series, Corvette.  The "87" is the body style, 2-door sport coupe.  The fifth digit is the engine, 4, correct for an L82 car.  The sixth digit, "8," indicates the model year, 1978.  The "S" is the plant where the car was produced, St. Louis.  The last five digits are a sequence number so this is the 19,247nd Corvette made for 1978.

Engine Code V0620 "V" means the engine was build in the Flint, MI plant.  The "06" is the sixth month of year and the "20" is the twentieth day of the month meaning the engine was assembled on June 20, 1978.  This is correct as it precedes the build date of the car.
Suffix Code CUT This means the motor was intended for a 1978 L48 Corvette with an automatic transmission, which is correct for this car.

Engine Block Casting Number 3970010 The engine block has the correct 3970010 casting number for a 1978 L82 Corvette.
Engine Block Casting Date F 14 8 "F" is June, the "14" is the fourteenth day of the month, and the "8" is the last digit of the calendar year so the engine block was cast on June 14, 1978, which is correct it predate the assembly date of the engine.

Intake manifold Casting Date E 31 8 "E" is May, the "31" is the thirty-first day of the month, and the "8" is the last digit of the calendar year so the intake manifold was cast on May 31, 1978, which is correct it predate the assembly date of the engine.
Carburetor 17058206 The original carburetor has the correct stamping for a late build 1978 L48 Corvette with an automatic transmission and a/c. The fourth digit, "5," means the carb was built in the 1976 - 1979 production run. The fifth digit, "8," means it was built for the 1978 model year. The six digit, "2," indicates that it is a 4BBL carb. The seventh digit, "0," means is was built for the Chevrolet division of GM. The last digit, "6," means it was intended for use in an automatic transmission car such as this.
Carburetor Date Code 1528 The firth three digits, "152," indicate the 152nd day of the year. The last digit, "8," is the year in which the carburetor was produced, 1978. So this carburetor was stamped on June 1, 1978.
Distributor 1103353 The distributor has a 1103353 stamping. This is actually a 1979 model year part number, but since this is a very late 1978 model it is very possible and common to see 1979 parts on the car.
Distributor Date Code 8F07 The "8" is the last digit of the calendar year, the "F" denotes June, and "07" is the seventh day of the month meaning the distributor was made on June 7, 1978. This is correct as it predates the assembly date of the engine.

Transmission Date Code B8K11D The "B" means the transmission as build in the Parma plant. The "8" is the year, 1978. The "K" is the seventh month of the year and the "11" is the eleventh day of the month. The "D" is the shift in which the transmission was made. This would mean the transmission was made during the day shift in Parma on July 11, 1978.
Transmission VIN Stamping 435624 The last 6 digits of the car's VIN, 435624, are stamped on the main case of the transmission and pictured below meaning this transmission is original to this car.
Windshield IJ "I" is June and "J" is 1978 so this window is original, made in June of 1978.  This is correct as it predates the build date of the car.
Driver's Window IJ "I" is June and "J" is 1978 so this window is original, made in June of 1978.  This is correct as it predates the build date of the car.
Passenger  Window IJ "I" is June and "J" is 1978 so this window is original, made in June of 1978.  This is correct as it predates the build date of the car.

condition

 
 

Exterior

The Two Tone Silver (13) and Charcoal (07) exterior is in excellent driver condition. As one can see in the photos, the paint has a terrific gloss and deep shine. Often Corvettes will have particularly chipped up front ends, this car does not. The original YJ8 aluminum wheels are in great shape with a brilliant finish and no curb rash. The BF Goodrich Radial TA tires have about 90% tread left. Both doors open and shut nicely. There are no major scratches, scrapes, or other imperfections that have been intentionally excluded from the photos. As one would expect from a paintjob with this many years on it there may be some small blemishes that were to small to show up in the photos, but nothing that is really noticeable from five feet away. There are NO RUST ISSUES with this car and as one can see in the many photos of the underside it is very clean underneath. The frame is totally solid with no rust around the "key hole" area in front of the rear tire and there are no signs of corrosion around the windshield, which are the two most notorious areas for rust on a Corvette of this era.

Window Date Codes

Please note that ALL of the glass on this Corvette, both side windows, the rear window, and even the windshield are all date coded and original as each piece predates the car's body build date of July 21, 1978 (K21). Original glass is a good indication that this car has had no major accident history and never sustained significant damage.

The car looks just as good in person as it does in the photos.


Interior

The Mahogany Leather interior of the Corvette is in spectacular original condition. The seats are in excellent shape and look just in person as they do in the photos. Please note that these appear to be the original seats and skins, not some cheap aftermarket replacements or seat covers. There is one spot on the passenger seat, but as one can see in the photos it is not very noticeable. The original carpet is in excellent condition with no stains, rips, or holes. This includes the rear carpet with is often neglected. All of the gauge faces are crisp and clean and the lenses are clear. The door panels are in nice shape and both door pulls are solid and in tact. Unlike many Corvettes of this age, the door panels actually fit well and tight to the door. The dash and console are in excellent condition with no cracks, sun damage, or fading. The radio works well and sounds nice. Most importantly the dash has never been cut or modified for an aftermarket installation. This car has not been smoked in and there is no cigarette aroma whatsoever. The original pedal pads are not excessively worn and, as one can see from the pictures, show normal wear for car with this mileage. The jack and jack handle are still present with the car and stowed correctly behind the passenger seat, pictured below showing the original stickers on the compartment lid. The original spare is still with the car and has never been used. Corvette interiors from this era are not known to wear well and the amazing condition of this original interior is a huge testament to the meticulous care this car has received throughout it's life.

The interior looks just as good in person as it does in the photos.


Mechanical

This Corvette is in great mechanical condition and it is ready to be enjoyed. The car starts right away every time, runs well, and idles well. It drives terrifically and it is smooth on the road and at highway speeds. In the video below one can observe the car accelerating on the highway up to about 70mph, braking to stoplight, going through some curves, and shifting through all the gears. Please note that there are no strange noises or vibrations and the car performs quite well overall. There is no blue smoke when starting or driving the car. The brakes are responsive and do not pull to one side or the other. The transmission shifts smoothly throughout the power band. This Corvette has plenty of power and is quite fast with the engine. Also, the engine compartment is beautifully clean, detailed, and correct as one can see in the photos.

The wipers work as do all the exterior lights, interior lights, turn signals, indicators, horn, rear defogger, and blower for the heater and a/c on all speeds. The a/c on this Corvette works and blows cold. One can observe the a/c compressor clicking on and engaging properly in the video below. All of the gauges work with the obvious exception of the clock. The entire vacuum system for the headlights works with no binding in the mechanism. Also, the headlights go up correctly with either the headlight switch or vacuum override switch. As one can hear in the video the car has a healthy exhaust note from the exhaust with no catalytic converter. Not enough can be said as to how much of a pleasure it is to drive this car, especially with T-tops out on a beautiful day.

The car runs and drives just as great as it looks.


Overall Condition

Overall, this 1978 Silver Anniversary Corvette is in fantastic original condition and an excellent driver. Special and Anniversary Edition Corvettes always draw a premium over their standard Corvette counterparts. The originality, the very low miles, the highly desirable options, the beautiful original color combination, and the great overall condition make this car especially important and hard to duplicate. Matching numbers is very important in Corvette pricing and as one can see this car is very correct. The prices of C3 Corvettes have increased drastically over the past years. This is especially true with the Silver Anniversary Editions in our experience. These cars have been catching up to the '78 Pace Cars in value and many people, myself included, prefer the Anniversary Edition over the Pace Car. This Corvette always gets a ton of attention driving down the road. It is very apparent that the vehicle has been well taken care of by its previous owners. The Silver Anniversary Edition Corvettes are secure and wise investments for a collector. One could easily enjoy this vehicle for several years and sell it for more than the purchase price with minimal effort.

 

Thank you for looking and please do not hesitate to email or call with any questions.
