Within Stock rules???

[Joseph Teuton]

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.

I agree with this

The reason I brought this up goes back to the rule book, I don't see any exemptions for cars originally equipped with titanium parts, valves or retainers.

"engines OEM-equipped with sodium-filled valves may use sodiumfilled replacement valves. Titanium prohibited"

"Any valve spring permitted, provided no modification to head is performed. Steel valve-spring retainers mandatory."

Jim - Both of those rules are in reference to replacement parts. The first rule about the valves was inserted at a time when the allowance for parts was not as liberal as it is now. Some versions of 427 Fords came from the factory with hollow stem sodium filled exhaust valves. The factory was the only source for the valves and discontinued production. Some racers petitioned to allow titanium valves as replacements since the hollow stem valves were lighter than available solid stem valves. There was some controversy that started because the West coast tech guys thought it was all right, but every body else did not. When it was pointed out that the titanium valves deviated considerably from the shape of the original valve and provided a two-fold advantage, i.e. lighter weight than even the hollow steel valves and increased airflow, the prohibition on titanium replacement valves was the solution. The second rule was included in the change to the rule to allow replacement spring retainers. When the rule was first drafted, it merely stated that replacement retainers were allowed. Of course the ingenious racers interpreted that to mean that ANY retainer was okay, including replacement titanium retainers. The additional statement prohibiting titanium was added to solve that. In both cases, the rule pertains to replacement parts, not OEM equipped. The factories can do whatever they want as long as NHRA accepts it, which is what we are seeing in the shootout cars.

Until they change their mind after you've already built all the engines based on an approved TI sheet.
