vehicle description

 

 

Seven Hills Motorcars is very proud to offer this completely restored, low mileage, and completely numbers matching 1974 Corvette Convertible in immaculate condition.  Let me start by saying that this is truly one of the nicest if not the best driving C3 Corvette I have had the pleasure to pilot.  The car has been used less than 1,000 miles since it received a total cosmetic and mechanical restoration.  There is no way that this car could be reproduced or duplicated for anything near the asking price.  The car is now in nearly flawless condition and needs absolutely nothing.  Everything on the car looks awesome, works as it should, and is ready to be enjoyed.  The underside of the car is almost as clean as the top.  Please be sure to check out the photos from underneath the car.  The low mileage is verified as original by not only the condition of the car, but also the clear Ohio title, pictured below, showing the mileage as "actual."  Please peruse the list of numbers below and all of the photos to get a true sense of how spectacular and clean this Corvette really is.

While the Corvette has numerous mechanical improvements and updates, cosmetically and in appearance it is totally stock.  This even includes the engine compartment and under the hood.  Everything was professionally and very tastefully done.  The previous owner was meticulous and it shows in the level of detail on this car.  The engine modifications are all internal and the block was not decked so it looks completely correct and still has all of the correct and original stampings and casting numbers.  Basically, the car was stored back to stock, but slightly improved as a driving car in the areas where it made most sense to update the 1970's technology.  The following list is word for word from the previous owner.

    "Every moving part has been replaced or rebuilt except the 4 speed transmission."

One may ask why a car with such low miles was completely restored.  The previous owner is a fan a past participant of the Hot Rod Power Tour.  The power tour is long distance driving event for classic cars; this year it will cover over 1,600 miles.  The previous owner restored this car with the specific purpose of using it in the power tour.  Since the Corvette has only two seats and limited luggage space, he utilized some of the other cars in his collection and this Corvette was never extensively driven.  That is why he did so much work to a car with such low miles.
 
A brand new restyled rear end was first featured in 1974.  The conventional rear bumper was replaced with a sloping two piece design.  This was the only year for the split rear bumper Corvette.  The new rear end eliminated the last vestiges of the long-lived rear-deck-lid spoiler and replaced it with a smooth-surfaced rear deck and a body-colored resilient extension covering the actual rear bumper and including the circular taillights meeting new federal energy-absorbing standards. 

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 cars 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.

 

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.  All of the parts I checked follow this rule and are dated correctly. 

 

item number description*
VIN 1Z67J4S412219 The third digit, "6," verifies that the car is an original convertible.  The fifth digit, "5," verifies that this is an original L48.  The sequence 12219 places the car's build date in December of 1974. 
Engine VIN Stamping 412219 The last 6 digits of the car's VIN, 412219, are stamped on the engine pad meaning this engine is original to this car.  
Body Build Date E13 "E" Corresponds to December, and the 13 is the thirteenth day of the month meaning this car was built on December 13, 1973.
Engine Code V1128 "V" means the engine was build in the Flint, MI plant.  The "11" is the eleventh month of year and the "28" is the twenty-eighth day of the month meaning the engine was assembled on November 28, 1973.  This is correct as it precedes the build date of the car.
Suffix Code CKZ This means the motor was intended for an L48 with a 4-speed, which is correct for this car.
Engine Block Casting Number 3970010 The engine block has the correct 3970010 casting number.
Engine Block Casting Date J 24 3 "J" is October, "24" is the twenty-fourth day of the month, and "3" is 1973 so the engine block was cast on October 24, 1973.  Which is correct as it predates the assembly date of the engine.
Alternator 1100544 The alternator is original and correct with a 1100544 stamping.
Alternator Date Code 4 F 3 The "4" is the last digit of the calendar year, the "F" denotes June, and "3" is the third day of the month meaning the alternator was made on June 3, 1974.
Intake Manifold Casting Number 340261 The intake manifold is correct with a 340261 casting number.
Intake Manifold Casting Date K 16 3 "K" is November, "16" is the sixteenth day of the month, and "3" is 1973 so the engine block was cast on November 16, 1973.  Which is correct as it predates the assembly date of the engine.
Exhaust Manifold, Right 3932461 The right exhaust manifold is correct with a 3932461 casting number.
Exhaust Manifold, Left 3932461 The left exhaust manifold is correct with a 3932461 casting number.
Carburetor Main Body 7044207 The original carburetor has the correct stamping for a 350ci 4-Sped L48 Corvette.  The third digit, "4," means the carb was built in the 1970's.  The fourth digit,  "4," means it was built for the 1974 model year.  The fifth digit, "2," indicates that it is a 4BBL carb.  The sixth digit,  "0," means is was built for the Chevrolet division of GM.  The last digit, "7," means it was intended for use in a 4-speed car such as this.
Carburetor Date Code 3173 The first three digits, "317" indicate the 317th day of the year.  The last digit, "3" is the year it was produced, 1973.  So the carb  was stamped on November 13, 1973, which is correct as it predates the build date of the car.
Transmission Main Case Casting # 3925661 The main case of the transmission has the correct 3925661 casting number.
Transmission Extension Housing Casting # 3978764 The extension housing of the transmission has the correct 3978764 casting number.
Transmission Date Code P 4 P 2 The first "P" means that this is a 4-speed Muncie, which is correct since the Borg Warner 4-speeds did not arrive in Corvettes until January, 1974.  The "4" is the model year, 1974.  The second "P" is the month code indicating September.  The "2" is the day of the month so this transmission is dated September 2, 1973.
Transmission VIN Stamping 412219 The last 6 digits of the car's VIN, 412219, are stamped on the main case indicating that this transmission is original to this car.  
Clutch Housing Casting # 3899621 The clutch housing is correct with a 3899621 casting number.

condition

 
 

Exterior

The Classic White exterior is in outstanding driver condition.  As one can see in the photos the finish has dazzling gloss and smooth finish.  Often many Corvettes will have particularly chipped up front ends, this car does not.  The underside of the front end, a very fragile part of the car, is in great condition as evidenced by the photos.  This Corvette came equipped with rally wheels, which are in excellent condition with absolutely no curb rash on the beauty rings.  The tires look almost brand new.  There are no major imperfections that have been excluded from the photos.  There are some small things when you right up on the car that were too faint to show up in photos, but nothing that is really noticeable from five to ten feet away.  The convertible top is in like new condition with no rips, tears, or holes.  The rear window is perfectly clear with no yellowing or cloudiness.  This Corvette has absolutely NO rust issues.  The frame is totally solid with no rust in front of the rear tire and I have seen no evidence of corrosion around the windshield. 

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

 

 

Interior

 

The Black interior of the Corvette looks utterly brilliant.  It is in near concourse quality condition.  The entire interior was freshened when the car was restored.  Even the parts that are original in the interior are very nice since the car only has 42,150 original miles.  The seats look almost brand new with no rips, tears, or split seams.  They are not worn in the typical areas such as where the driver gets in and out.  The carpet is in like new condition as well with no stains, rips, or holes This includes the rear carpet with is often neglected.  The console is in great condition and fits together correctly.  The door panels are in great shape and unlike many Corvettes of this age, they fit well and tight to the door.  The dash is not cracked or sun faded at all.  This car has not been smoked in; there are no burn marks or aroma whatsoever.  Please note that detail items, such as the pulls for the rear compartment doors, have not been pulled off on this car.  The original pedal pads are not excessively worn, and as one can see from the pictures, show normal wear for a car with this mileage. 

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

Mechanical

Even with the beautiful cosmetic condition of the car, the mechanics are the real highlight.  This car is in extraordinary mechanical condition.  There are no issues at all with this Corvette and it is 100% turn key.  Even the a/c and clock work.  All of the mechanical items on this car have seen very limited use since the car was restored.  With the all new springs and the updated suspension components the car drives terrifically.  It is very tight on the road and at highway speeds; it is the best driving C3 we have ever had.  The car starts right away every time.  There is no smoke when starting or driving the car.  The stainless steel brakes are responsive and do not pull to one side or the other.  The transmission is solid and the car shifts very tightly.  The shifter has a very short throw and very confident and precise feel.  The clutch feels great.  Everything on this car works as it should, the headlights go up and down with the headlight switch and the vacuum override switch, all of the gauges work, all of the interior and exterior lights work, the horn works, etc.  This Corvette has plenty of power and is very fast.  Not enough can be said as to how much of a pleasure it is to drive this car.  I have personally driven and enjoyed this car all summer with absolutely no issues at all. 


Overall
Condition

 

Overall this 1974 Corvette convertible is in spectacular condition.  There is no way that this car could be duplicated for any amount near the asking price.  Numbers matching is extremely important in Corvette pricing.  The originality, the stunning condition, the very low miles, and the great extent to which the numbers match make this car especially important and nearly impossible to duplicate.  Cars like this are the Barrett Jackson stars of the future.  The 1974 or 1975 Corvette convertible is the star of today and the future in terms of an investment; it is beyond doubt one of the most sound and secure ventures one could make into the Corvette market.  One could enjoy this vehicle for several years and sell it for more than your purchase price.
