So work on your combo , spend more $ to run faster and get a HP hit for your hard work and lighter wallet? The logic does not work. Why would any one do
this?
Yes the rules have gotten out of hand with what Stock was originally about but there the current rules. Change them to what everyone thinks is best then hire qualified tech inspectors to enforce rules, but Penalizing HP because of your NHRA rules is not the best way to equalize the playing field. (If that's NHRAs goal here).
I would be in favor of a personal index adjustment in heads up situations to level the field.

OH YEAH! And the Choir Boys in Stock Eliminator won't manipulate that! Just look at the mess in Comp!

My combo is rated from the factory at 365.
I would be in favor of treating my 365 factor the same as this one:

Mopar 426 365 291 295 1964

Would you then be in favor of running a manifold from an Olds that came on late 50s engines along with an AFB that flows 575 cfm in place of your QJ that flows 800 cfm. Would you give up the valve to piston clearance and long stroke that allows you so much more cam than the 426 SW can run.

So the combo just got horsepower and is still rated 70 horsepower below the factory rating.The Oldsmobile driver just "needs to work on the car".
BTW,I don't get the 800.And it was checked at St Louis by tech.

Gotcha.

They bring a flow bench to tear down, never saw that.

Why would anyone run the 2206000 intake, when you can use a '68-71 440 HP intake? I certainly wouldn't use the 516 heads either when I could use a 915 that's 19 cc larger on the intake side...

For what it's worth, I have a '65 Coronet 426 SW car, and have had no issue finding those intakes or heads that they were originally equipped with.

I'd probably use the 2206000 because you could buy one for $135.lol

The Mopar's have always been at a disadvantage. We are stuck running 50 and 60 year old intakes. They make aftermarket heads but good luck getting them. Very little to no aftermarket blocks or cranks.
I guess we'll struggle through.....
