[Stephen & Horace Johnson]

why did they make them all automatics?

[Andrew Hill]

Wow, respect for GM. These HP ratings are much more reasonable than the Drag Paks and Cobra Jets started with. They still may need some HP, but not nearly as much as the others. Just compare the N/A 427 to the 428 CJ rated 50 less to start with. The stocker supercharged motor is rated higher than any of the CJ blown motors are now, too, with, it sounds like, the same blower. Not sure how the SS motor's rating compares to the CJs.

[442OLDS]

I expected the horsepower ratings to be much lower too.

Hopefully,they will still qualify at Indy with these horsepower ratings.lol

Well now. If this is THE PACKAGE! We can BLAME the new roller rocker rule for stock on this package! Say thanks Chevrolet owners!

Did you miss the Callies crankshafts?

Surely a "Depends" moment!

How about titanium valves!

[Alan Roehrich]

I believe someone warned all the "new car" fans about opening Pandora's Box a couple of years ago. You opened it, you wanted it opened. Don't whine about what comes out of it now.

Oh, for the uninitiated, a few points.

1. None of the OEM companies build all of their own parts. It's called "tier I suppliers", look it up.

2. Some of the actual production Corvette engines have had titanium valves and other parts in them for years.

3. At least these cars are starting with factors that are remotely plausible.


The "factory race cars" belong in Super Stock, in their own classes, as it had been done for decades. No one would complain about them if they were where they belonged.

Welcome to the "new" Stock Eliminator. Hope you like what you're getting, you asked for it. There will be more just like them from all three OEM's next year.
