Back in the 60s, did Chevrolet (or GM) ever manufacture a 428 cubic inch
engine?? If so, what's the history behind it and what models did it
power??
Thanks,

Can't think of any. There were 427's from at least two engine
families: the rare NASCAR-only "Porcupine" on the old 348/409 block,
and the later one from the 396 family. This latter also was made in
aluminum-head (L88?) and all-aluminum (ZL1?) versions. The latter is
very rare, offered only in a special lightweight Corvette with, among
other things, no heater.
Ford, on the other hand, had a 428; this was from the tamer side of
the FE engine family, and its higher-performance sibling was the famed
side-oiler 427.

Chev had the 427 from 66-69.
Pontiac had a 428. in 1965??? I think it was offered in the Bonneville.
Pontiac guys.....chime in here....

I seem to remember the Pontiac as a 421 cid which was pretty strong as
the 421 Super Duty.
In 1970 Pontiac again bored out the 428 from 4.12" to 4.15" and increased the
stroke, from 4.0 to 4.2" making it the 455 CID.

The only 421 I ever saw in a Goat was a tradin on a Hemi Satilite at
the Mopar dealer where I worked. It had a skip and was sent to us in
service to repair whatever the problem was. It was in and out over
several days and we had an opportunity to play with it. One of the
guys in service had a TriPower Goat that could handle it quite easily
in a backstreet contest. I can't tell you if it was a factory option
ot not but, we had a couple of dealers around Atlanta at the time that
would put together anything you would pay for.
Thanks for the info!
Pontiac put a 428 in the mid-60's Catalinas. They were considered performance
engines, and usually had solid lifters and high compression.

That's right, you don't want to rev a big pontiac. That may explain why the
389 didn't seem too shabby next to the 421. 400 pontiacs, and smaller, have
smaller main bearing journals.
In stock form true. I know of one local firebird running in the high
tens, Edelbrock heads, big roller etc with a 455 and I know he turns it
to 6500 or so. Another 69 Tempest, similar engine goes low tens. So they
can run when modified.

The closest you get in the major industries to that magic number of the 420-
something block is:
Mopar=426 Hemi
Ford= 427 and 428
Buick=425
Chevy=427
Pontiac=428 (don't know if they made a tri-power version of this engine)
Good luck,
Is there a reason for the interest?

Also the 430 for Lincoln; I think this was also from the FE engine family.
There was also the 429 that replaced these engines around '69. Well,
actually two different 429's, but the Boss 429 "Blue Racer" is fairly
rare...

I think I did confuse it with the 421... nearly identical, except for state of
tune.

As far as I know, Chevy never made a 428, though I believe that Ford did.
Chevy did make a 427, that in various stages of tune was put into their
passenger car line, as well as the Corvette. In the Corvette this engine
was available in several versions, developing 390 hp, 400 hp and 435 hp.
There were also pure competition versions, notably the L88 which probably
put out close to 500 hp, and the ZL1 which was an all-aluminum version of
the L88 that probably cranked out close to 600 hp. Only 2 ZL1-equipped
Corvettes were made. Please note that the hp figures are for gross hp.
Presently net hp is used which would give a lesser figure.

I think it was a different family. I had one, 34 years ago. There
was also a smaller version in the Edsel, a 383, I think. I always
wondered why Ford never did anything with this block. It looked
VERY strong, very beefy rods.
>> Buick=425
And a 430, in the later engine series. I think the 425 was a bigger
401, the old nail-valve block. Remember the vertical valve covers?

Actually the 430 was from the MEL engine family, not the FE.

I've never heard of a 428 Chevy. Other posters have been correct about
the Ford and Pontiac, and Cadillac had a 429, I believe.
One note of correction, I dont believe the L88 had aluminum heads. It was
a honkin' motor for sure, but I believe it it was all-iron (block &
heads). There was an L89 engine, iron-block, aluminum head. The ZL-1 was
all-aluminum and made it into two Crovettes in '69 and 69 '69 Camaros.
(not a typo). I believe the ZL-1/L88 were pretty much identical (ie-cam,
head design, intake) except for the iron/aluminum difference.

No, it did have aluminum heads.

Yes. This was the L71 motor, AKA 427/435, with aluminum heads.

Where did the 406 come in? Was it of the FE family?

The 360 hp 352 of 1960 begat the 390 hp 390 GT which begat the 405 hp 406
which begat the 410 hp (4V) and 425 hp (2x4V) 427 which led to the 427 SOHC.
The 428 CJ was made from a different mindset, although the basic idea ("make
car go fast") was the same.
The 359 and the 391 were industrial truck motors. The 410 was Merc only.
The 361 was Edsel and Merc.

As I understand it, the reason for the 428 CJ was to bring costs down,
the 427 block had to be hand bored due to close tolerances, while the 428
could be robot bored since it used a standard 390 block with lots cylinder
wall to work with. The 428 CJ replaced the 427 for the 68 model year, and
some dealers were having "close out specials" on 427 engines for around
$500! Wish I'd bought a couple of dozen. Of course I also wish I still had
the 65 Mustang GT convert I sold for $125 in 73.
> The 428 CJ replaced the 427 for the 68 model year,
Technically, the 428 CJ replaced the 427 from April 1968 onward.
