Is there a west coast rule book for IHRA?

Not trying to argue, Just trying to understand what is legal in IHRA. My car in NHRA can run AA/SA, A/SA or B/SA, It has the Nascar Hemi with thin gauge steel and hood scoop. It is currently rated at 440hp with a minumum weight of 3690 in A/SA. It is the long wheelbase with a P/W factor of 8.09.

Where does it fit in IHRA? I heard IHRA uses the original factory HP ratings, So does that mean I'm at 400hp? Fiberglass instead of thin steel? Fiberglass hood scoop?

Why are there only a few racers that have set records in IHRA? Almost all classes are at a minumum..

Can I really run the 71 demon hood scoop on my 71 duster?

Thanks for the help guy's

IHRA's AA class is 7.00 lbs per HP. Your car would run A/SA with the single NASCAR 4 barrel at the same factor and weight. You could run AA but could you get to 3080 lbs plus 170 (3250) for the driver? The cross Ram Hemi is de rated to 470 HP in stock for AA and can use the 1 inch shorter wheelbase for a Hemi car. Dan Davorak has a 64 Alum front end Plymouth that fits that class with the X ram but Im not sure if he is able to race yet with his health problems? . No fiberglass in place of the thinner steel. The fiberglass is for 1963-64 Alum front end cars with Max wedge or 64 Hemi cars only. McCormack ran one a few years ago in IHRA. Hood scoop must be steel also on the 65 cars but who even looks ! .
Most records are at min. because there is no incentive to set one. No points and the NHRA guys look down their nose at the IHRA deal anyway. Most think its to much trouble to tear down and as I understand the IHRA has a policy of if you want a record you show up with the engine already torn down (on Fridays I believe)......Its inspected THEN....you put it together, it is then sealed and you run during the time frame allowed for records on Saturday..
You need to call Hank Blakenship (Tech guy) at 276-531-8654 or Danny Waters Sr. (tech guy) and you can email Danny from this forum to be 100% sure of this as its been about 10 years since I have worked for IHRA. Some things have changed in that time. But be aware that they will be in Va. this weekend for the TOC race. The middle of the week next week would be the best time to contact either of those guys. Jim Woods is also a stock S/S tech guy for IHRA and you could contact him from this forum. Check with these guys about the Duster hood scoops.
I hope this helps a little.

I like the tear down before record run that way if there is something slightly wrong you can correct and make it legal,seal it, then set your record.

It does make sense, but what if you pass tear down but then can't run fast enough to set the record? That would be irritating.

Then they seal the motor and it's good for the rest of the year! You can go to another event and set the record with a sealed motor and no tear down. IHRA has a policy that allows you to tear down at the beginning of the year and be sealed and your good for the rest of the year. That is what I did this year and set the record twice. No tear down at the track! Makes it muck more enjoyable. Jim
