'66 Impala SS427

[Marina66SS]

I am new to this site and I thought that I would say hi. I currently have a '66 Impala SS that I just bought back from my dad. I bought the car originally when I was 16(ten years ago) and when I bought it the guy said he had just pulled a 427 out of it and it had 427 badges on the fenders. I am curious as to whether I can make sure it is a real 427 car. I haven't found any build sheet and both the motor and badges are easily replaced so I don't know what it was originally. I know it is a factory SS running the numbers. It has a TH400 on the floor with buckets. It also has a 12bolt. Is there a way to tell between a 427 or 396 car? Is the suspension or frame beefier on the 427 car? Is there a way I can track down factory or dealer paperwork? Also I was wondering about the side chrome. Is this on all SS's or an option? I was thinking about taking it off since I am doing the body work on it now. Thanks for the info guys.

Welcome /ubbthreads/images/graemlins/smile.gif
I used to own a 1966 Impala with an original 427/425 HP engine.
What is your build date and plant on the Cowltag?

[Marina66SS]

If I remember right it was built in Feb in Janesville, WI.

Well Jason, I can't really help you with your question, but welcome to the Supercar Forum /ubbthreads/images/graemlins/wink.gif. Must be nice to have a 66 Impala 427 and that planned Marina Blue 66 Chevelle SS as mentioned over on the TC board. Good luck with this one as well.

Jason, If the tubo 400 is the org trans the car would have been 390hp 427 Did 66 have the same hood as the 67 ?

[Belair62]

No special hood on a 66 Impala regardless of motor as far as I know.

[Marina66SS]

So you are saying that if it had a TH400 that it was a 427 car? Didn't 396 cars have TH400's?

My mother brought one of these cars home brand new.I'll never forget it.I was sitting on my minibike in the driveway when my ma came up the street with it.It was that muslane blue convert. with black top and interior.I could see the BB flag form a distance and thought WOW!! a 396 but when she pulled in the diveway I saw the 427 on the fender.My ma didn't know anything other than it was a convert.

No what I meant was that if it was a 427 car it would be a 390 hp. No turbos came behind a solid lifter hi horse motor until the 68 gibb novas. It could have been a 396 I don't know?

Jason,
I am not real up on the '66's but for starters, Look on the drivers side near where the linkage goes into the case. Look around for a VIN stamping. If there and it matches the car then procede to look on the transmission tag mounted on the passenger side. There should be a large letter 'C' on the left and another letter on the far right. If it is a 'A, C or H', then it is for a 396. If it is a 'B' it is for either a 427 or a police 396. Not all Turbo 400's had VIN stampings on them so do not be alarmed if there is none. If it is there but doesn't match the car's VIN, then the above doesn't matter. I do not believe there are any other differences to the car between a 396 and/or a 427 in '66.

I thought the 1967 Model year was the first year for the TH400 in a Chevy /ubbthreads/images/graemlins/confused.gif

1965 Caprice I think
