2012 Rules Are Posted

There are stud conversions that do not require machining.

You are allowed to drill and tap for screw in studs anyway.

The question would be, if NHRA requires the OEM configuration, what does NHRA consider the configuration of the Olds and Ford 5.0 to be? It's not a shaft mount, by any stretch. But neither is it a stud mount.

I'd suggest anyone considering making changes wait until at least after the PRI Show next week in Orlando, and what ever you decide, get approval from Glendora in writing, and keep it with the car at all times.

Aftermarket rockers. And more spring pressure. And nothing about ratios which will work much better with different ramp angles on cams which will require more spring pressure. Speeding up opening and closing intervals. And you can only get so much spring without bigger diameter valve pockets. (next change) Sounds reasonable to me------------In SUPERSTOCK. If you can't make a stock rocker live with the mods allowed you probably should be running in a class that already allows aftermarket rockers. Not screwing up a class that is screwed up enough by all the whining, and aftermarket BS that has already been allowed. As many have stated deregulating spring pressures caused this.

Just what we need, or so I'm told, more classes. I thought the manufacturers wanted less classes? Which is it?

As others have already pointed out we have roller rockers, 5 lb weight breaks for ASCJFU/S, and window safety net guidelines but yet they still won't allow good seats??
