1966 Chevrolet Impala 427 non SS questions
 

Hi everyone. I have been asking questions on the Yenko site to get information and some understanding on some cars I am going to be selling for my boss and good friend who recently passed away.
This was his 1966 Chevrolet Impala w/ factory 427 cu. ci. and it is not an SS. I have read that the SS was not a performance package but that it was just a trim package. I have heard from several people that this car is rare because it has the 427 and is not an SS car. The numbers show it to be a v8. The engine appears to be untouched and seems to have the correct brackets and hardware and the hose brackets seem correct. Is there a way to verify that the car did in fact come with the 427 engine? I included a photo of the tachometer. I would think the red line would help in determining the engine. Thanks, Gary C.

Gary,

Check for the stamped numbers on the engine pad in front of the right side cylinder head.

And can you post pics of the vin and cowl tag and I'll decode them for you.

Great. cowl tag shows a red/white top/red bench seat plain Impala convertible built at Los Angeles.

tinted glass, air conditioning, TH400 trans, convenience group and deluxe seat belts. The TH400 code means it was a big block.

See if you can get a picture of the engine pad numbers. Also, the tag attached to the side of the TH400 transmission case, will ID the engine.

Thanks for the info. I will get photos of the engine and transmission info. in the morning. Is it rare for the year and model to have a big block and not be an SS? Is there any way to get production numbers for this version of the Impala?

Here are some interior photos. The only thing not original in the interior is the radio. What radios were offered in '66? I have looked on eBay and found several but not sure which one would be correct. Also the floor mats say 427 Impala I'm not sure if those are original or aftermarket.

I would say it "IS" a 396-325hp car with 427 fender flags............

Re: 1966 Chevrolet Impala 427 non SS questions
 

Agreed. The tach is talking.

IMHO "427" emblems are alot cheaper than a true 427 motor -- I've seen "LT-1" decals on the hood of Vettes' with the base engine in em' ... TAZ
