Okay, so you're talking about converting a factory race car like the COPO or the CJ into a regular stocker by adding additional equipment?

What advantage would a car like that have over a regular production car prepped to Stocker rules?

Is a Strange 9" rear legal in a production Camaro?

I was thinking of some other things too like instrument cluster and HVAC controls. Door mirrors? Did COPOs have tubular bumper supports like CJs?

Yeah, I was going to ask the same thing, but didn't want to clutter up my post. The live-axle conversion (from IRS) would be legal, but I think the Ford 9" would need to be replaced with a GM axle to be legal as a regular Stocker.

9" is legal for 2008-up, but it does still say "Distance between
OEM backing plates and OEM wheelbase must be maintained". One look at wheel offsets tells you the race cars have narrower axles than the street cars. I guess this rule is either ignored or doesn't apply if a 9", although it doesn't say that anywhere.


It also says "Coil-over shock or four-link adaptations prohibited". Isn't a COPO a 4 link? They have coilovers too don't they?

Last portion of this post was very instructive.

Zero. If you follow the current rules and take advantage of the aftermarket replacement parts that are allowed you will end up with the same car.

As far as the rear end width, you will have to consult the tech department. My thought is that they allow "factory spec. replacements.

Okay, so if I'm understanding correctly, the real risk to me isn't the CJ platform itself, per se- the real risk to me would be that someone with much deeper pockets than me would develop this particular engine to the point that they cause the horsepower to be factored to the moon, making it much more difficult for me to even run under index.

Do I have that right?

Not necessarily. But, it is a risk that we all take. As long as they don't run 1.2 under, you can protect your combination by lowering the average. I doubt that you will see many of these for a while.

I'm not a class racer- is 1.2 the threshold for AHFS?

I just don't want to spend $20K or so on a retirement hobby, just to get torpedoed by something that I never saw coming.

Again, I have no interest in setting a record or racing at Indy- I just would like to be able to comfortably run under index.
