IHRA Pure Stock
 
This is just an inquiry. I've been looking over the rules for this class. If one had an unmolested car, looks like it could be a fun class.

The engine rules look pretty simple, basically the same rules from the early 70's. No trick engine parts. You can run the old style stocker camshafts, no radical ramps. Do Comp or Bullet make these cams?

I notice that you are required to have a driveshaft loop. Can't see where some of the lower class cars would need it but simple enough to fab one up.

I'm a little fuzzy on the open exhaust/header rule. Do you have to run the exhaust thru mufflers? Are you alowed to run open headers, have to retain the exhaust?

If I'm reading the "Weight Adjustment" correctly. You can add or remove weight to go up or down a class, just like regular stock?

Like I said, looking this class over. My partner and I may end up with a car that would be a good candidate for this. Just what I need another project.

If you have headers you have to run through mufflers. It does not have to be a full exhaust system ,all you actually need is mufflers and they cannot be straight through type.Other words you should not be able to look in one end and see out to the other end.

If you don't run headers ,you are allowed to run cut-outs or open exhaust....
I am pretty sure if you went to the first race and it did not suit the tech ,they would probably give you a race to fix to their likings.....

Does the original style auto trans have to be used ? ( i.e. 4 spd overdrive auto in a car that came from the factory with it )
I had heard of guys using a C-4 3spd auto in cars that came with AODs and the same for GM and Mopar guys.

Unfortunately for me, I just heard that my local track does not allow Pure Stockers at their S/SS combo races. :(

Unfortunately, Ohio Valley is not Pure Stock friendly. :(
I found that out yesterday straight from the track manager.
IHRA Stock GT racers are SOL as well.

The only IHRA Stockers they allow are crate motor.


That only leaves 2 races for me this year. London and Mt. Parkway.

I guess somewhat understandably. Probably more than a few guys don't want to be embarrassed by having their 50-100k Stocker or Super Stocker beaten by a dime rocket. Don't know why they dis the GT stockers. Most of those aren't cheap to build and there probably aren't a dozen of them in the whole country.

This deal wasn't as lucrative as we initially thought. The old car was pretty rough. Already have two setting in the garage that need to be finished. At present, don't need another money pit. Maybe if something else popped up down the road, I'd still be interested in trying to put something together for this class. Looks like the only place to run it would be an IHRA points meet or National.

It sounds like the tech guys at Ohio Valley are to uninformed or dont know how to tech a pure stock car unless they hire someone good likeTravis Miller......Now he could bust some balls.....LOL. Why do you think NHRA stopped checking cam duration, overlap and valve spring pressures back around 1985 ! Not only that they might have to get down on the ground to check for the correct transmission.

why do they allow Crate Motor Stockers at Ohio Valley and not allow GT or pure stock? They are alot closer to stock than the crate motor cars.
