COPO 427 ?

[427king]

anyone ever see a motor like this??

[TC]

Nope!

Looks pretty interesting though.

I'm no expert, but I would not think it came from the factory that way....but like I said, I'm not an expert.

I would post it for JohnZ to see on the first gen site

[Keith Tedford]

Any of the engine stampings that I have seen have four numbers. These "CS" letters don't refer to any '69 Camaro or Chevelle COPOs that I know of.

-------The COPO appear to be gang stamped and the broach-marks look OK on first view. Weird!!!......Bill S

I'm not sure what the date is, I see 08052, August 5th? What does the "2" indicate? http://www.yenko.net/ubbthreads/images/graemlins/confused.gif

[PeteLeathersac]

With the Tonawanda build of 0805, that Suffix should be 2CS..

On Suffixes that start w/ a number keep in mind the known 4T & 4U Suffixes for the '68 Chevelles...also remember that L36 Suffix we were all looking at a few months back in the Canadian '68 Big cars...was it 3S?.

What's the castings and dates on this one indicate...maybe early '69 car?.
It couldn't possibly be a for a 68 car...could it?http://www.yenko.net/ubbthreads/images/graemlins/eek.gif.
Vin sequence anywhere?.

If the suffix code is 2cs that would indicate a '70 Marine motor 427/390 Crusader L-36 single 4BB with a normal rotation

[clopo]

That info comes from the MSA-1 Chevy Big Block Suffix Code book dated Dec. 2000 second release pg. 106

She is not a L-36 marine engine as posted earlier then Chuck. I have seen COPO factory stamped on the pad of two BBC engines and they also had it on the cowl tag right at the bottom.I don't remember the codes that came after the dates but both were installed in 68 full size chev 4 door police interceptors ordered with a 427 425 hp and a m22.Talk about a chase car. I am not sure if they offered the same COPO option to the 69 full size but my guess would be that motor is out of a very rare police car.

Would either of those two cars be considered a "supercar"? http://www.yenko.net/ubbthreads/images/graemlins/grin.gif http://www.yenko.net/ubbthreads/images/graemlins/grin.gif http://www.yenko.net/ubbthreads/images/graemlins/grin.gif

With the L72 being an RPO in '69 in the full size cars, there would be no need to have a COPO designation unless I'm missing something.

[/ QUOTE ] Im not familiar with the police cars but i do know there was a white COPO 396 police car on ebay a few years back,and i know 396s came in chevelles[maybe it was the model that it came in?? that made a certain engine a COPO order???

[John]

If it was for a special police car....
...would the special speedometer make it a copo? http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

[TimG]

It could be for a number of reasons including special suspension or shocks, heavy duty radiator (AC radiator in an non AC car), special wiring harness, towing package in a car it's not available, special gearing. I don't know if any or all of these would demand a COPO order, but they could. Weren't there some special order 4 banger Novas that John Z talked about? They had a crummy drive-train combination that made them barely able to climb a hill, but they built them under the COPO designation.

I hear what you are saying Keith and yes you could just order a full size 69 with the l-72 with a RPO but you could not order a 69 police car with one that would be a COPO order. That is the difference.
Not sure on 69's but I know 68's police cars had both the 120 and 140 speedo and some had the tach and guage package.
Many assume all had the 140 but that is not true.

[Keith Tedford]

GM seems to have done a lot of odd things. You just never know. What you say sounds reasonable to me.

[Belair62]

Skokie Illinois Police had 69 Full size 427 chase /dick car and also 426 Polara (?) unmarked.

Police cars again !!! Real police cars have a 140 certified speedo!! I know the 68 thru 72's have them. My 70 and 71 both have 140 's the 70 with special gauges in the cluster replacing the clock, Water temp, Amps and Oil pressure, The 71 these same gauges are in a housing under the dash. Police cars were COPO orders as they were unique the branch of service required. Mine have neat options and deletes and colors!! More info if needed.

Hi Jim:
You may have 70 amd 71's but you are not correct for 68. I don't know about the rest of the years. I parted four 68 factory police cars over the years and know of a couple of others. Of six cars two had the guage package and two the 140.Both with the 140 didnot have the guage package but I have seen a few examples of that combination also.It was not standard in 1968 for sure for all police cars to have a 140 or guages.
Here is probally the rarest 68 police car ever produced a factory COPO 427 425 HP with a M22, F41 and 12 bolt posi. We had the twin of this car in our home town. It had quite a reputation and this picture is of the second one we have ever run across. As you can see guages but only 120.I have pictures also of a 396 car with a 140 and no guages. Have to like the mouse and the sun glasses.This sucker on the highway would chase down just about any muscle car out there in the day.396 and 427 oval ports were in the police packages common and all auto's. A square port 427 with a 4spd very rare.

Here is one mounted in my '68 SS427 Impala. Notice it has a slightly different configuration then Joe's example.

Whttp://www.yenko.net/ubbthreads/images/graemlins/eek.gifW Mac...L72/M22 Chevy Cop Cars!!!
Any more you can lay on us on these?!.

My '67 RCMP Biscayne Ghost Car has the original 140 Speedo..
Just a stock suffix L35 396/M40 Auto but has 'RED TAG RCMP' on the Cowl Tag...best of all it's a 2Dr. Post!.

I'd expect the Dodge in Belair's post was a Coronet or other midsize?. Dodge/Plymouth had a whole range of Police units available w/ unique Vin prefixes, body styles and engine options but didn't offer 426 Hemis in the full size line..

-------I wonder how many swear words were uttered as they were trying to chase down some miscreant while trying to row the Muncie shifter thru the gears??? Wonder also how many times those troopers got the trans stuck in two gears at the same time??? There are probably serial speeders out there that never got caught, dont you think???.......Bill S

I get a bit dizzy thinking of those barges at 140mph.....Man, that's gotta be cool! http://www.yenko.net/ubbthreads/images/graemlins/3gears.gif http://www.yenko.net/ubbthreads/images/graemlins/3gears.gif http://www.yenko.net/ubbthreads/images/graemlins/3gears.gif
