why not
you can't buy a mustang or a dp from the dealer
i think that would be cool and a 289 snake

Re: 2012 Rules Are Posted
 

I was referring to current stock legal darts/barracudas to be allowed to convert over to a hemi and run in one of the new classes since the weight breaks are for super stock only.

I purchased my Drag Pak from Southland Dodge.

Re: 2012 Rules Are Posted
 

Looks prety simple to me..........

The cylinder head rules in Stock didn't change and that states "The following are permitted: polylocks, jam nuts, screw-in larger-diameter rocker studs or pinned studs, bronzewall valve guides"

The ONLY rule that chaged was the ability to use aftermarket rocker arms and they did NOT have to be (as the old rule was) "Aftermarket rocker arm must be identical to OEM. Either adjustable pushrods or adjustable OEM rocker arms permitted on any application, but not both. OEM roller rockers permitted ONLY if application was originally equipped with roller rockers"

The difference is now the rule says "Aftermarket rocker arm permitted. Either adjustable pushrods or adjustable OEM rocker arms permitted on any application, but not both.

Looks like stud mounted roller rocker arms for the OEM stud mounted engines and T&D's for the OEM shaft type rocker arms.

I don't like the rule but is seems pretty clear on what their intention was.

Re: 2012 Rules Are Posted
 

I wonder what will be acceptable for pedestal mount rocker arms like Olds or some Fords?

Re: 2012 Rules Are Posted
 

ok why is this happening??? So i guess before to long the jackets, neck braces, and gloves will have to be renewed?

Re: 2012 Rules Are Posted
 

Paired shafts, like the Harland Sharp offerings, or stud mount conversions.

Re: 2012 Rules Are Posted
 

Alan
You mention stud conversions for a small Ford 5.0. IMO, that would take machining the head to accept a stud and milling the pedestal to accept a guide plate, correct??
That would be a no no as I am told............am I wrong and lots of racers have done this and that makes it ok? I would love to go to a screw in stud and a guide plate and toss the dumb azz shims kits in the trash.

Re: 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.

Re: 2012 Rules Are Posted
 

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?

Re: 2012 Rules Are Posted
 

You know I wondered how long it would take for these folks to find 1 more thing for us to spend our money on. Guess buying a new window net every 2 years won't break the bank but where does it end? Heck we've got the local circle track racers buying our outdated belts to run....they have no time limit rules, guess they're alot less likely to crash.

Re: 2012 Rules Are Posted
 

X2 , where the heck did this come from ????!!!!!!!!!!!!!!!!!!!!

just go ahead and dilute us again cause of a few whinny people (or rich) get there way!!!! sounds like US politics, buggar !!!!!!!!!!!!!!!

Jim, You have a pm.

Re: 2012 Rules Are Posted
 

I just want to change my seat so when some dude having a mid-life crisis crosses the centerline behind me in his 8.50 9 inch tire car and punts me like a feild goal kicker, my seat doesn't fall apart.. Oh! Or me... But hell everyone else wants roller rockers and pro stock spring pressures.

Re: 2012 Rules Are Posted
 

The seat must not be important keith just get a nice window net instead

Re: 2012 Rules Are Posted
 

X3 Bernie!!

I hope all the whiners and cry babies are happy!

Re: 2012 Rules Are Posted
 

Agree 1000%; like Alan and others have said, the new rockers will just move the weak link to another component (my spare $1200 "OEM" rockers now being virtually worthless), meanwhile they want us to spend $ on 'safety changes' that make the SCCA crowd laugh. Guys wearing their pajamas brought about the pant rule (which I agree with because it truly advances safety) and now others whine because they can't fix their rocker arm issues and cause everyone to spend a bunch of money to update their stuff which they worked to figure out and make work. Chances are the net thing is just because some racers use raggedy old nets so NHRA wants to uphold the "appearances". I guess well anchored true racing seats just makes too much sense, besides wouldn't want to violate the spirit of "stock". Take a good look at some of the 'stockers' that some master craftsmen have built and tell me how a good seat would in any way take the car away from 'stock'. Give me a break..

Re: 2012 Rules Are Posted
 

They are! Once again they got their way. To He// with everyone else.

Re: 2012 Rules Are Posted
 

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??

Re: 2012 Rules Are Posted
 

idiots, the lot of em

Re: 2012 Rules Are Posted
 

I assume this puts Clark Holroyd's rocker arm system out to pasture? Also, what does this do to the high dollar hydraulic lifter market?

Re: 2012 Rules Are Posted
 

i do not see anything about roller rockers
it says rocker arm are not roller rocker arm

Re: 2012 Rules Are Posted
 

SECTION 10A: STOCK CARS, ENGINE: 1, ROCKER ARMS (Page 5)
OEM or OEM-type aAftermarket rocker arm permitted. Either adjustable pushrods or adjustable OEM rocker arms permitted on any application, but not both. Aftermarket rocker arm must be identical to OEM. Either adjustable pushrods or adjustable OEM rocker arms permitted on any application, but not both. OEM roller rockers permitted ONLY if application was originally equipped with roller rockers.


Note that the part in red is actually "struck through" in the NHRA publication, meaning it is the old rule that was amended and no longer applies. The part in blue is the new rule and the portion of the old rule that remains.

So here is what the new rule, by itself, actually says : Aftermarket rocker arm permitted. Either adjustable pushrods or adjustable OEM rocker arms permitted on any application, but not both.

The removed the part of the rule requiring the rocker arms to be identical to the OEM rocker arms.

What that means is that aftermarket rocker arms no longer need be identical to the OEM rocker. The only aftermarket rockers that are not identical to OEM rockers are race type roller rockers.

Note also that the rule as written and published is exceptionally and unacceptably vague. Nowhere does the new rule stipulate or specify that the OEM ratio or mounting configuration must be retained. By the letter of the rule, shaft mounted 1.9:1 rockers are not prohibited.

Now, of course, the NHRA position on this will revert to their standard "just because we did not tell you that you could not do that, does not mean that you are allowed to do that."

Re: 2012 Rules Are Posted
 

There is already a rule about stock ratio rockers. Jeff Teuton ran into this problem on record tear down.

Re: 2012 Rules Are Posted
 

All these "insert # of A's" stockers going 8s on 9 inch tires sound like a disaster waiting to happen to me. Or as was mentioned before , a 160 mph car drilling a 100 mph car in the rear in the lights. Good luck to everyone.

Re: 2012 Rules Are Posted
 

That rule changed. They removed : Aftermarket rocker arm must be identical to OEM so there is no longer a written rule saying the OEM ratio must be retained. The part listed in red above is what required the OEM ratio.

Supposedly the rule will be amended, again, to require the OEM ratio to be retained, as well as the OEM mounting configuration.

Re: 2012 Rules Are Posted
 

Only people who have never seen the wrecks in the " 10.5" tire power adder" classes running low nine and faster ET's would think a 3200 pound car on a 9" slick with a power adder running 8.50 at 160MPH in Stock Eliminator is a good idea.

Re: 2012 Rules Are Posted

After inquiring NHRA, I got a reply stating that an amended, more detailed explanation will be added in the near future.

Re: 2012 Rules Are Posted
 

Wow, parked the stocker for 3 years and it's amazing how far behind I am now. I have been gathering up to date parts to put it back together and the list keeps growing.
Now I need a aftermarket block,and roller rockers, enough already.

Re: 2012 Rules Are Posted
 

[QUOTE=Alan Roehrich;295110]That rule changed. They removed : Aftermarket rocker arm must be identical to OEM so there is no longer a written rule saying the OEM ratio must be retained. The part listed in red above is what required the OEM ratio.

The legal rocker ratio for your combo has always been listed on the engine blueprint sheets. The VERY unclear new rule states you may now use roller rockers. Doesn't say you may now change your rocker ratio.

I think the only thing this new rule has created is more drama...................

Re: 2012 Rules Are Posted
 

Monte you do not need a after market block or roller rockers. You need 3 speed transmission.

Re: 2012 Rules Are Posted
 

[QUOTE=7423;295118]I'm well aware of where the rocker arm ratio has been listed.

The new unclear rule does not say anything about your new aftermarket racing roller rocker arms being identical to the OEM rocker arms they replace, anymore, either.

Re: 2012 Rules Are Posted
 

I agree, I was understood roller rockers were ok but it does not say that ???

Re: 2012 Rules Are Posted
 

Sorry if I missed it. Window nets, ribbon type, new one with a date ? If so, wonder what the market is for 3yr old ribbon ones.

Re: 2012 Rules Are Posted
 

Too bad the clowns in Glendora don't have an expiration date.

Re: 2012 Rules Are Posted
 

"like"

Re: 2012 Rules Are Posted
 

A more detailed explaination will be added in the future.

With the amont of sentences detailing how I can't use mouth wash in the morning or I might be booted and fined I would think that adding the words "stock mounting and stock ratio will still apply" wouldn't be too hard to have inserted in this great document..

When reading the rule book I find that if you play by what it says you are two years behind. Its what it dosen't say that is the mystery.

Re: 2012 Rules Are Posted
 

Monte, why jack around with a 2 or 3 speed.

Just put a 4 speed in! It is a heck of alot more fun!
