Jack their are people out their running "BAD" combos.....as hard as it is for you to belive most people pick a car that they like,luv,or just already have instead of going out look for a "combo " car. (not I but) so their you have people with "combos" that have been beaten to death for years (example 67,68 camaro with 327/275) (just an example not picking on anyone) & now don't stand a chance running for class against these "combo" cars. Thing is even with valve job & 3 speed I don't think they can run with the FI cars or the mopars! (just a fact) Then again You were @ INDY /U.S. nationals so I think this might be a way to help make tec easier........?

Whats next - And for 2009 , they'll allow port matching.

Re: Revised Valve Job specifications posted NHRA.com
 

Wow, throw in the much overlooked sentence out of the rulebook"Runners and combustion chamber must retain OEM appearance" and it looks to me like I'm allowed a set of any steel valve with any angle, any custom made seat at any angle (taper?), any bowl job that I can fit under the seat and any port work that I want as long as it appears to be stock. Why don't they just start pouring heads and be done with all of this crap!

Amen, Mr. Bill.

S/SS Combo, anyone? :rolleyes:

Maybe they'll have the rules finagled out before I get my butt up to PA and get the head off the Turismo. Sorry, got caught up with doing some post-PRI 'emergency' stuff for some folks... how about just before or just after New Year's?

Re: Revised Valve Job specifications posted NHRA.com
 

The way I read it, one of the stock valve seat angles must be retained, somewhere amongst the other angles.....;)

Re: Revised Valve Job specifications posted NHRA.com
 

Billy I agree! Just wonder how many "stock " heads out their wouldn't pour?

Re: Revised Valve Job specifications posted NHRA.com
 

Upon further review from the replay booth,I'm not so sure that this means you can do anything you want.

Re: Revised Valve Job specifications posted NHRA.com
 

Billy and Greg; If you contact Mr. Bachelder and ask "when are you guys gonna pour stocker heads?" The answer will be: some in 2008, all in 2009. I dont think it will be wise to get too carried away with the bowl hog or the "stock appearing" ports. We like the idea of a valve job that is not subject to interpretation but we are gonna be pretty careful from that point on. Others will do well to exercise caution it this area. We all know that many stocker heads wont pour, even at SS volumes.

Re: Revised Valve Job specifications posted NHRA.com
 

they have been pouring them for 2 years with no action
very few would pass on publishede ss specs

greg... watch your glass house...

1. you loved the nova. parked it for a BETTER combo
2. your valve job was in mix questioned at indy, which helped the new bull**** rule get pushed through
3. have you poured you head yourself ??

i still love you... but in reality the indexes are a sham, and the tech guys are not allowed to enforce rules

It would also help if NHRA provides the proper and quality measuring equipment, with proper calibration, to the Tech Staff. That would stop a lot of the bitching and questioning during tech. As an example, you cannot use a plastic burrette in the field for tech!!! Get an electronic burrette with a digital readout...they are affordable and NHRA has the budget.

The same goes with dial indicators; it does not take much to disturb the clocking mechanism after they are dropped in the ground. Also, get some borescopes for internal inspections; if they are good for the FAA for inspecting a turbine engine, they should be good for inspecting an engine.

By the way Jack...a very realiable source that is trustworthy, told me that the last reading Travis did on Doug Patrick's controversial cylinder heads, were done with a different burrette and the heads were in the tech area and not taken away.
