Well let me help you unless you remove the whole rear end you will be down there on the ground measuring and checking, the 9 inch and 8/3/4, you can set them up with the center clamped in a vise so it looks like your letter is very self serving. Like it's been told to many with the older cars, if you want the new stuff than get a new car!!

Shows how well you think things out before trying to stir things up!

I don't see where the request to allow aluminum 9" and 8 3/4" center sections have anything to do with the new cars or the extra labor involved with gear changes in a Dana 60 or 12 bolt. It's for racers who already have the 9" or 8 3/4" in their cars and would like a replacement option for them that is stronger, safer, can provide contingency opportunities and makes the factory happy because they can sell more parts! NHRA, in typical fashion, confuses the situation by not being specific and allows at least Mopar to post contingency for them. Of all the things that NHRA has allowed with aftermarket parts, like blocks, heads, etc., an aluminum carrier would likely have the least amount of performance benefit.

I'm curious if Mopar posted with NHRA for their aluminum 8 3/4 center sections in Stock in years before the Drag Pak Challengers were introduced. If so, then it would imply that they would be legal in older cars! Any Ford or aftermarket postings in years before the Mustangs came out in Stock?

last year we got gigged on the vertical brace in front of the radiator on a 67 Camaro--this is the support piece that goes from the hood latch mechanism to the core support we honestly forgot it when we put the car back to gether after painting it------Tech said it absolutely had to be in there--so we went to a bone yard got one from a 1968 olds 88 4 door sedan sprayed it black and put it in with zip ties put the bolts in a plastic baggie did not fit but it was in there --He was happy !!! bunch of BS ---Also did not like the way the roll hoop behind the seat was bent but we had a letter and pictures from NHRA Tech ok'ing it kinda ruffled his feathers a bit but F him --He passed it after about an hour going back & forth over some other small stuff wrong knobs on the radio kinda **** if ya know what I mean---stuff that had absolutely NO impact on performance simply cosmetic crap---comp

Myron,
The answer to your question is yes. I have been paid for an aluminum rear assembly by Chrysler several times, however it was when I was driving the FWD Spirit. Jim

I thought the rule book said any corporate rear. I know several people who run aluminum spools.

There is no rule I'm aware of on internal components, aluminum spools are legal, from what I understand.

The only real advantage to an aluminum center section is a reduction in unsprung weight. Unless of course you use an aluminum 9" center section that accepts GM 12 bolt components.

Once again, we have bigger issues than this in the class, this is merely another minor distraction.

Do I think aluminum center sections should be legal? Not really, and certainly not if aluminum radiators and drive shafts are not legal for cars not originally equipped with them. Do I think aluminum center sections are a huge issue? Not really, so long as they are not the ones that accept 12 bolt parts.

Then NHRA needs to be more specific about what they do instead of causing more questions & confusion. If they allowed Mopar to post for their aluminum center sections and pay out for their use for years, how can anybody think that they are not legal? Why would Mopar spend the money and post for something that isn't legal?

Yes, 10lbs can be a small performance advantage because it can be relocated to a better location. But it's considerably less than the aftermarket brakes that are allowed! As far as unsprung weight, the benefit is negligible in a drag car. It would be a bigger advantage in Nascar, offroad, etc. where there is considerable and constant suspension travel.

This would be a good time to make the rules for Stock the same as Super Stock except for the engine and tires. Let roller rockers in stock, there is no reason to blow a motor up because you break a stamped steel rocker.

[Alan Roehrich]

No thanks to roller rockers in Stock Eliminator. We've got enough "performance enhancements" already. Give them roller rockers and they'll just break something else. If you're breaking enough rockers to have a recurring problem, then something is wrong. We haven't broken a rocker in 6 years, and we average around 125 runs a year.

Maybe you need MORE spring pressure and MORE RPM's to test the parts......
