Impala or Biscayne?

Hi Guys,

New to this site. Just wondering if what I have came from an Impala or a Biscayne? I am not an Impala or Biscyane expert by no means. My engine pad says the following:

T1230ID
6J183406

The engine is 4 bolt main cast in 1965, standard bore, original TRW pistons, standard 6223 crank, 858 heads and 069 intake.

Purchased this engine in Chicago approimately 6 years ago. Owner said it came from an Impala but just wanted to confirm.

Thanks,

Vic

Welcome to the Team Vick!

The Chevrolet Engine Application Code "ID" returns to a 1966 Special High Performance (350 horse RPO code L-79) 327 four barrel equipped motor out of a Full size car (it doesn't specify which model B-body it came out of; so it could be out of a Biscayne, an Impala or a Caprice).

Here is a picture of your motor in a 1967 Malibu

Dave, What are your sources? The L79 was never available in a fullsize car. The ID engine suffix is special high perf 427/425 (L72) and is from a fullsize Chevy.

Vick, can you post a picture of the engine pad? What's the casting date on the side of the block? Dave is right that it could have come out of any model B-body. I don't have that partial vin in my database so who knows. Definitely a cool motor though.

The ID engine code was also used on a 1966 327 Special High Performance engine in the "Full Size" car. I have a set of books from Colvin as well as looking at Nasty Z/28 a Second Generation Camaro site (1970-'80) that has good tech info.

Hi Guys,

The block casting date is L 14 5. I have included several pictures of the engine stamping.

That looks like a BBC to me. So as usual Warren is correct. You have a special high performance 427 not a 327. (I wonder if the four books I have had a typo four times as well as the web site?)

That website has a lot of misinformation with the application codes. I remember others telling me to stay away from it. As far as Chevy by the Numbers, by copy gives the correct info for the ID suffix.

Thanks guys!

I suppose it is nearly impossible to tell whether it came from an Impala or a Biscayne.

It was probably out of a Biscuit because the Biscayne (being just a stripped down Impala) is lighter than the Impala. There are only two ways to win a drag race: one is to increase the amount of power; the other is to reduce the car's weight.

In 1966 the Camaro wasn't out yet so people where still racing (on the street and on the track) the full size Biscuit, because aside from the Corvette, that was the only way you could order a 427 IN A CAR BODY.

I always ordered my 427 L-88 motors as a service part from my local Chevy dealership and installed my crate motor in any body I wanted. I started with a light weight 1967 Chevy II, but switched to a 1968 Camaro after discovering that a Chevy II with a BBC was a bad idea. I raced a series of Nova bodied two door sedans all powered by big blocks (usually the 427 but I also had 454's that I put together out of aftermarket pistons and a 454 crank that was available over the parts counter in 1969).
