Built in the first week of December, 1968, this 1969 Chevrolet Chevelle SS L78 is finished in factory-correct LeMans blue over black vinyl interior.
The car is a complete rotisserie restoration on what was a very nice original car. We have extensively checked over all of the sheet metal and believe it is all original to the car. All of the factory spot welds are in place, there is no seam sealer where panels have been added and the fit is excellent. The paint is a base/clear two stage job on top of a wonderfully straight body. The doors, hood and trunk all fit as well as they ever did. All of the glass is new on the car and has been restamped with the correct SoftRay factory markings. The trim on the car is excellent and fully restored and the chrome is wonderful as well, with the front bumper actually being an NOS part still retaining the GM Parts sticker.
The drivetrain has been completely rebuilt and the motor is original to the car, with a partial VIN stamping on the front of the block. The engine code of JD is correct for a 396/375 HP engine paired with a 4-speed transmission. The motor was built on November 11th and the car was built in December so everything pairs up correctly. The transmission is date code correct, however, was not born with the car. It has the factory correct Muncie linkage and shifter. The rear end is a CI code which is for a 3.73 posi. The housing was cast on November 13th which precedes the build date of the car. These CI code rear ends were only founds in L34 and L79 Chevelles.
The Holley Carburetor is the correct unit for the 1969 Chevelle and was built in the second week of November. Both exhaust manifold castings are for the 1969 Chevelle with a 396. No matter what the HP output, the exhaust manifolds for all the 396 cars were the same. The water pump was built in November which is correct for the car, and all of the front drive pulley appears to be original GM part numbered pulleys. The heads are correct "Hi Performance" square port heads. The passenger side has the correct date casting for the car, although the driver’s side has the casting number of a dealer replacement unit that GM used. Obviously it was damaged and replaced by the dealer many years ago.
The exhaust system on the car is a chambered NOS unit. It is not aluminized and even has the correct oval shape as it goes under the transmission brace. It also has the factory correct exhaust brackets at the the rear of the car, and resonators with the factory weep holes. The car also has the correct BO code radiator which pairs with the 396/375 HP motor with a manual transmission.
The suspension of the car is fully rebuilt and retains the correct cast finish. The drive shaft is the correct bare finish as well, and even the spiral shocks are correct on the car. Not only do all the wheels have the correct YA stamping for a 14×7 SS wheel, but they also have all the same date codes.
