I understand stock is no longer stock, and nhra ihas allowied the class to become modified product cars with something that resembles a stock car.
As far as hydraulic lifters, if there was no power gain why were they schimmed to act like solid lifters and now that they have to have only .010 movement it doesn't change the performance of an engine over a standard factory hydraulic? The valve lash was then built in to the lifters versus adjusting at the valve.

Nhra doesn't want to do their jobs that we "all" pay for, police the cars and HP factoring. That's what it comes down to.

Because someones car doesn't perform like other people's cars doesn't mean that they don't work hard at their combo.

BTW, the Chevy 302 is factored to 309 HP, that's 1.023 Hp per cubic inch. How many hydraulic lifter engines are even close to that?
