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

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

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 ?

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?

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.

What gear ratios does the 572 come with from factory?

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