Roller Rockers in Stock

[treessavoy]

Simple question: does adding roller rockers make the car any faster?

That is the defining question.

No, it is not the defining question.

You forgot several questions.

Does it change the character and spirit of the class?

Does it open up the potential for cheating?

Does it further escalate the RPM range?

Does it merely change the name of the part which breaks?

Add roller rockers to the class. Then the only real difference between Stock Eliminator for 2012 and Super Stock of 1985 is roller cams and lifters, and the intake.

I personally like the change.....welcome to Comp Stock Eliminator....9k RPM 396.......AWESOME.......

To update my Olds, I'll have to get guide plates, screw-in studs and new hardened pushrods as well. Plus, it's just one step closer to Super Stock.

Jim your car already runs like a Super Stocker ...

Maybe now they will legalize the Olds Edelbrock head for Stock,since they are already allowed on some Fords and Chebbies?


Olds Edelbrock Head:


ROCKER ARMS: Roller rocker arms are required- stock
rocker arms will not fit!

And before anyone thinks that I am for these changes,I am NOT!

Anybody needing Edelbrock heads,roller rockers,metric 200 trans (in cars that never came with one),trick lifters,etc should have been put in Super Stock LONG ago!

Aubrey, I doubt yours are any wilder than ours. If you're breaking rocker arms, and you upgraded as we discussed a while back, then you have some sort of control problem, I'd bet it is costing you horsepower. If the lobe is so radical you can't control the valvetrain, I'd be surprised if it is making as much horsepower as it could be.

Exactly what I was told...5-6 years ago...when I was running 10.50 - 10.60's in D/S...by those that were 3 tenths slower than me.
It's almost funny. You guys will scream about roller rockers but not one of you are screaming about $850 BBC rockers with 9/16" studs or $500 to $850 Tool steel or Schubeck / Smith lifters. And the $950+ billet steel cam cores on 50mm or 55mm journals are silently ignored.
Maybe, just maybe, those with the exotic stuff, don't want the little guy that can't afford the trick stuff to "catch up" with the allowance of roller rockers or their $89 lifters and $150 camshafts?
Any of you break a rocker in eliminations at a NHRA national event? I have. Lucky it was my bye run into the semi-finals. Had there been somebody in the other lane, I would not have made it to the finals. And lucky I had my bucket of spares with me too. My runner up finish was over $5,000 in winnings. I don't think $279 rockers sound like a lot of money when stamped rockers breaking can keep you out of the next round.
And I'm sorry, but NHRA didn't allow crate motor factory Super Stockers in Stock 30 years ago either.
Allowing standard $279 Crane Gold type rockers in Stock is actually good for the little guy. And so are a set of solid lifters with EDM hole oiling for around $89 over the $850 composite lifters and $950 billet cams.

Does it change the character and spirit of the class? Yes, But so do CJ's, DP's and COPO's

Does it open up the potential for cheating?No more than it is already. Lift is still measured at the valve.

Does it further escalate the RPM range?It probably will.

Does it merely change the name of the part which breaks?To be continued

Add roller rockers to the class. Then the only real difference between Stock Eliminator for 2012 and Super Stock of 1985 is roller cams and lifters, and the intake.Head work, Radiator, Seats, rear chassis, Throught the firewall cages (don't know if that goes back to '85 or not). But its not 1969 or 1985 anymore

Just making conversation. No disrespect intended
