2023 COPO Camaro 632
 

I am curious if we will see any of these in the divisionals or national events this year. Does anyone have there deposit down? Ray

Re: 2023 COPO Camaro 632
 

Are they in the guide, I see a 572 but not a 632?

Re: 2023 COPO Camaro 632
 

I was talking to Chevrolet at PRI, and they said that the NHRA was giving them a hard time about acceptance into the guide.

Re: 2023 COPO Camaro 632
 

Is it like the Demon, where there is no class that would accommodate the HP/weight ratio?

Re: 2023 COPO Camaro 632
 

I read somewhere that it is not NHRA Stock or Super Stock legal.

Re: 2023 COPO Camaro 632
 

You know damn well it will be in the guide shortly. GM wouldn't build it if they knew they couldn't race it.

Re: 2023 COPO Camaro 632
 

The NMCA has added it at 530 HP.

It is my understanding that the NHRA doesn't like it.

Re: 2023 COPO Camaro 632
 

The 572 (500hp) in FSA has a 9.70 index and will probably run in the high 8’s.
The 632 is more likely a 572 on steroids, 530hp is laughable, more like 1,000hp. I can see NHRA’s problem, where do you put them?

Re: 2023 COPO Camaro 632
 

In a naturally aspirated Factory Stock showdown class. Have a supercharged class and a NA class, like they did from the beginning.

Re: 2023 COPO Camaro 632
 

The 572 won't get near that as delivered. The original rating submitted was 430 HP, which is a much more realistic number. My 6.2 LT will out run it at C weight....

That 1,000 HP is what the motor made on the dyno. Since when has any Stocker been rated at the TRUE number ?

Re: 2023 COPO Camaro 632
 

if your comparing rated hp/weight performance I can understand it needs a rating to wind up in a class and be somewhat competitive. Most ratings are low compared to true hp, but the specs on the 572 are far above most of the high hp stockers and its potential should be far above them also. Is there a cork somewhere in that engine?

Re: 2023 COPO Camaro 632
 

We received the first 572 COPO in February last year and had it at a track two days later. So, I have quite a bit of experience with this combination.

It is probably the most consistent COPO that I own.

The throttle body is the same one that's on my 302. The cylinder heads are the same castings as the 396/375. I have a pretty good idea of how Chevrolet's test session went. I also have my own data. I ordered the car with the understanding that the HP would be 430. The 500 HP rating that the combination was given is a big disappointment to us.

As delivered, the 572 made just a little over 720 HP on Jeff's engine dyno. My 302 made right around 600 HP on Holley's when I lent it to them to test the Terminator X.

I have no doubt that there is room to pick the combination up. We are experimenting with some stuff right now. I just can't bring myself to throw a big pile of money at this car.

Re: 2023 COPO Camaro 632
 

My '15 DP 392 is rated at 430.

Re: 2023 COPO Camaro 632
 

Yes, and it will outrun my 572 all day long....

Re: 2023 COPO Camaro 632
 

What gear ratios does the 572 come with from factory?

Re: 2023 COPO Camaro 632
 

It has a 2.48 first and 4.11 rear. The stock tune hits the rev limiter before the mph clocks.

Re: 2023 COPO Camaro 632
 

Maybe a hand crafted race car with a 632 cubic inch purpose built race engine doesn't belong in "Stock Eliminator" which originated as a class for factory production assembled car cars with at least 500 units made available and in the hands of the general public.

I like running against the new high performance production cars, but what is being allowed in stock eliminator has gotten ridiculous. Maybe that's the sticking point for NHRA?

Re: 2023 COPO Camaro 632
 

Gump!
Come now!
I saw that combo go 8.7’s in SS trim with my own eyes!

Re: 2023 COPO Camaro 632
 

I agree.

With the 572 and now the 632, Chevrolet has created "WOW" cars that really have no place in Stock or Super Stock.

Re: 2023 COPO Camaro 632
 

Yep, a BIG pile of money that got HP for the showing.....

Each to their own, but not what I want to do with the money I earn.

Re: 2023 COPO Camaro 632
 

As delivered..........

1969 COPO 427 ZL1 Camaro's were 12 second cars as delivered......

Re: 2023 COPO Camaro 632
 

The 572 2022 COPO Camaro would have received a HP reduction if it was submitted for review in Stock eliminator.

Re: 2023 COPO Camaro 632
 

The ZL1 was not "dragstrip ready" as delivered. Do those modifications and it ran A LOT better. Add 50+ years of rule changes and it's rated only 15 HP above the factory rating. Do you have dyno numbers that you can share on that combination? It was competitive in 1969 with very few modifications and I believe it's still competitive at it's current rating?

Re: 2023 COPO Camaro 632
 

We talked about that, but in the end we decided not to request one.

Re: 2023 COPO Camaro 632
 

Chevy makes a big deal about those engines making 1000hp.... why can't it be rated at that? I'm sure with the allowable overbore and cam duration and blueprinting it should be OK. It's as legit a Stock combination as the injected 427 SOHC flip top 67 Comets are...

Re: 2023 COPO Camaro 632
 

For the same reason that the ZL1 wasn't rated 550 HP in 1969...

Re: 2023 COPO Camaro 632
 

Im new to the COPO deal i have raced stock with a c/sa 68 chevelle 396/375. I have a 2022 COPO 427 i got the car at the end of november with no place to test. I live in New Mexico so that does not give you a lot of places to go in the winter time . does any one know how fast the car should run at sea level. the way it came from the build center. I was just wondering what to expect. I know i will have to change up tune ups as i go. Thanks

Re: 2023 COPO Camaro 632
 

DG, that horse left the barn in 2009. And it was the sanctioning bodies that let it out. I think that most Stock racers agree that ALL (Mopar, Ford, and GM) FACTORY BUILT RACECARS belong in Super Stock, or Comp. ... (anyone that has ever owned one knows it) ... However, that's not the way it is, and it is 2023, and this is the hand we've been delt. If you wanna keep running Stock Eliminator there's no choice, other than deal with it.

Re: 2023 COPO Camaro 632
 

Randy, depends on class you intend to run ( weight ). Car at FS/B weight
from the factory, my estimate would be .4-.5 under index. But you will
need to get a good tune on Holley. Welcome to the world of COPO racing.

Re: 2023 COPO Camaro 632
 

thank you for the info just wanted an idea of what to expect.

Re: 2023 COPO Camaro 632
 

Agree, the horse has left the barn on FS, but I think Stock is on a very slippery slope and if were not careful incremental changes will cause it to loose its identity over time. Look at Super Stock since the '90's. First NHRA allowed the modifieds into SS, then GT cars, later FWD GT cars, then the FSS cars and now FGT. Super Stock has changed a lot in the name of progress, one increment at a time. I still love super stock, but as a bit of a purist, I want to protect and preserve what's unique and special about Stock Eliminator.

Re: 2023 COPO Camaro 632
 

The Modified classes were placed in Super Stock (some of them) when NHRA killed Modified Eliminator in order to give us Super Gas, after the 1981 season. The GT cars came in shortly afterward, to encourage the OE's to invest in drag racing, since nothing they were building to sell was of any interest to 99% of racers. The FWD GT classes came a bit after that, as a natural extension, when the OE's almost completely ceased rear wheel drive production. The Factory classes are much like the FI classes were to Stock a few years ago, pretty much the only way to protect the traditional cars and combinations from being completely annihilated, and made totally obsolete.


IHRA tried the Crate Motor Stock and GT Stock classes, th'ey didn't get picked up by NHRA, and I doubt NHRA is considering it now.



The Factory cars, years ago, would have been treated like the Super Stock Hemi cars were, and shoved straight into Super Stock, but not allowed in Stock, except for, once again, NHRA wanted a cash transfusion from the OE's, and wanted the OE's to get involved again.


I can remember a close friend, who shall go unnamed, came to dinner in our pits one night, about 2010. He proceeded to tell me that he didn't "see how the Factory car he was driving could be in AA/SA with our ancient 69 Camaro 427/427 (435)". They had pulled the engine out, and put it on the dyno before they ever made a pass. He told me that "it made more than 100HP out of the box" than my relatively competitive 427/425 did.The two cars were rated almost the same, his was at 425, ours was at 435, because we had 401 heads on it. So he was 10HP/75# lighter than we were, and 100+HP better, without turning a screw. Admittedly, we were never a threat to set the A/SA or AA/SA record, but we have a few class trophies, and a few heads up wins, so we weren't a back marker, either.


I'm all for a combination starting with a rating that makes it relatively attractive and competitive. But having a 100+HP advantage on the dyno and a factor/rating 10HP lower than an established combination is pretty much just stupid.

Re: 2023 COPO Camaro 632
 

Which Stock Eliminator rule was changed exclusively to let the factory cars participate?

The only differences between a COPO and a Camaro in Stock Eliminator legal trim are the motor and the hood. There were several cars built in the late sixties specifically for Stock that fit the same format. The A12 Mopars come to mind.

There are a few combinations that I think should not have made the cut. But honestly, what are the automakers doing today that is so different from 1969?

This continual bashing of legal cars is getting old.

Re: 2023 COPO Camaro 632
 

A12 not a good example Gump. My buddy bought an A12 car off a used car lot in 1974. It had about 30000 miles on the odo. I'd like to see a late model COPO with similar mileage.

Re: 2023 COPO Camaro 632
 

A lot of the "factory car" combinations were either never actually produced as a running vehicle at all (there were some Cobra Jet engines that not a single example was ever even assembled by Ford), or there were never 50 of them built in a year.


If you offer 50-60 total cars for sale, and have 2-4 or more engine combinations available in that year, and a few of each engine combinations are sold, the NONE of them hit the "50 sold" mark.


They took the 1967 L-88 Corvette out of the guide, for only 36 being sold (more than enough to make it "legal" went out the back door) through the dealers.


I've said this several times. If the "50 sold" rule is waived for the "factory cars", then the 1967 L-88 Corvette should be back in the guide.

Re: 2023 COPO Camaro 632
 

I find it interesting that you would take one of Mopar's baddest built-for-competition cars and reduce it to a grocery getter to try to make a point. I guess the street Hemis were great for hauling the kids to the beach too?

Re: 2023 COPO Camaro 632
 

I think that would be COOL!

(Would it run Stock or just Super Stock?)

Re: 2023 COPO Camaro 632
 

I bought an A12 Roadrunner that held the National Record and I
raced it AND drove it to work for years. Whole different time and tech
in stock in early 1970s. My brother drove a A12 Super Bee to High School!

Very Streetable cars with mild camshafts and not a ton of Valve spring pressure (About 140 to 150 on the seat). There were 4 A12s on the street in our little town back then not counting the dedicated trailered cars.
