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.

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

What gear ratios does the 572 come with from factory?

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

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?

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

I agree.

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