The thing I don't get from the article is the changing of the cam, to a larger grind? How can you tell this "Stocker" engine from a "SS" engine??
In this case it wouldn't be very hard they bragged about it in a magazine article.[/QUOTE]

All the NHRA would check is correct port and chamber volume and for valve size.
When they refer to larger camshaft, they may be referring to the duration, which you are allowed to run any duration you want. The lift of the cam is the only limitation for the camshaft.

I think its cool that they are opening up and sharing with the masses , and at the same time training the next generation of engine builders.
Exactly...hard to educate some that are unwilling to learn, and then you have others that get there feelings hurt to easily.

I think the engine is awesome...the only questionable mod is touching up the short turn. Now if that was part of the CNC program that was approved....its all good.

carry on

Guys I think we are overlooking the fact that the "shootout" cats have different rules from regular stockers. SAM is a great company and I can assure would not do anything outside the rules. Let's not get the two mixed up... But hey I'm not a very smart man!

I've read many complaints here about the cars not being subject to the AHFS, so these cars can also have engine modifications not legal in stock eliminator as well?

But the "Shootout" cars that do not qualify for the Quick 8 go back into regular Stock eliminator and then are not subject to the AHFS! Yeah, that is fair!!

So if you protest one of these cars that transferred into stock and they're found to have titanium valves, main girdles, extra porting work or whatever are they going to get tossed?

Don't know what is common between the production Corvette LS7 and the shootout engine, but the Corvette has CNC ported heads, titanium connecting rods, and Intake valves . They (GM) should have probably changed the code from LS7 to something else, to avoid confusion .

Nothing is common with the OEM factory showroom engines.
These are dedicated race engines and race cars with their own unique specifications for a specific class.

I agree Mr. Larry! They should not be able to run the eliminator. The top dragsters that don't make the field do not get to run S/C... Once it's teched in as a shootout car it should not be considered with the Stockers.

Jim Mantle,

No they will not be tossed because this engine has been deemed legal by NHRA since it's inception in 2012 for either Stock Eliminator and or the Factory Shootout.

Larry and Joseph,

I don't agree the Shootout cars that do not make the quick 8 should not be allowed to compete in Stock Eliminator. However, I do agree that once they are placed in the Stock Eliminator field they should go to the bottom of the ladder and no longer be exempt from the AHFS for the balance of the event.
