1969 Impala SS427 (Z24 option package) and includes the following:
- Frost Lime exterior color
- Black vinyl interior w/ front bucket seats
- Black vinyl top
- Console
- Tilt Steering
- AM radio
- 8 track tape player w/multiplex
- Tinted glass
- L72 425ci/425hp engine
- M21 close-ratio Muncie 4 speed transmission
- 3.55:1, 12-bolt posi-traction rear axle
- Simulated wire wheel covers
- Power steering and power brakes

Sometime in the mid-seventies, circa 1975-1977, the first owner (1969 - 2002) had the original L72 engine removed from the car and replaced it with a small block. The owner said that this was done due to the rising cost of gasoline; he has no clue as to the whereabouts of the original block. I have notarized affidavits from the original owner, the mechanic/neighbor who performed the engine swap and the owner of the dealership that ordered/sold the car, attesting to it’s originality. Other evidence that the car had the L72 option: single 3/8” fuel line, original “CN” emissions sticker on radiator support and the original distributor, which was found in the small block that was in the car.

The NOM small block has been replaced with a correct, date-coded NOM 512 “CE” block, correct 840 heads, solid lifter cam along with correct, date-coded: alternator, aluminum intake, starter and carburetor. The transmission is the original M21 w/ VIN stamped on top, the rear axle is original to the car and it appears to have the original spare tire as well. The interior is original except for the carpet and front bucket seat covers. A complete body-on restoration, documented with lots of pics, has been performed, bringing the car to like-new condition. Everything, including the 8 track player, works. It drives, sounds and runs fantastic. The only non-stock items: spark plug wires, radial red line tires, battery and SS exhaust. I will furnish all pertinent date codes and casting numbers to anyone interested. Asking $52,500. 706-602-5055

Here are some links to a few pictures, I have not figured out how to make them appear in the thread yet:

Looks like a very cool car. L72 Impalas are very rare. I would have to speculate that the exhaust manifolds are also not stock for an L72 nor the master cylinder. 3/8 fuel lines also applied to V8s other than the L72 option.

Good luck with the sale.

I do not profess to be an expert on the Impala but according to the research I have done the exhaust manifolds are stock w/correct casting numbers per Colvin's book and have been powder coated. Although the 3/8" fuel line may have been used on the 390 hp SS427 it also had a return fuel line; the L72 did not and my car does not. I did not look closely at he master cylinder though so you may be right.

They cant be the CORRECT numbers because they do not have the holes in them for the smog setup. All 4 speed cars in 69 and all solid lifter cars had smog! Wrong air cleaner also. It looks like a nice car you have but with no paperwork or original engine its really hard to be sure its a 425 hp car. At 52k I would think you would need something. 69's are hard cars to get the money out of. There is a true 42k mile 425 car around here with paperwork thet was just sold for 25k.

Hey Don what color and trans was the one that sold for 25k?

--------Wouldnt the exhaust manifolds have the same casting numbers weather or not they had the smog holes drilled in them??? I know this is the case with Corvette manifolds..........Bill S

Yes,and the 1968-70 Impala BB used LH #3914613(Impala specific),& RH #3916178.
His application would denote A.I.R.tapped manifolds.

Thanks for your comments GTO Don, I am glad to have finally found an expert on the 1969 Impala SS. As far as my asking price goes, if I need any marketing advice I will let you know...

No problem.

Don,
What’s the story on the Blue Z in your driveway? A friend of mine is in the market for one.
He is shopping for a 70-71 and has looked at a bunch of rust and fakes, We looked at a 70
Z/28 in Delaware this week that was a waste of time and gas. If he does not fine one soon I
was thinking of selling him my 71.
